Along with the growth and expansion of cities during the time, several parts of them have depreciated and they require repairing and inspection. Damaged places and repairing them are a problem that is significant and liable of each period has been looking for excogitation and resolving problems according to the existing circumstances. However, expressed concern that it is still a problem, is worn texture, which is extending fast in all cities of the world, particularly in developing countries, and this problem has gripped cities and authorities. In spite of all weaknesses and deficiency, since the majority of worn-out tissues have significant cultural, social and economic values which give identity to the cities, so paying attention to these areas and how to intervene in them is very important. The purpose of this paper is to study and consider ways of rehabilitation and renovation of the old texture of Ab-Anbar-No district in Sari, which it has been done using analytical-descriptive method. In this study, the needed information has been collected by observation, providing necessary map, library research and rehabilitation and reconstruction strategies have gained by SWOT model for analysis and internal factors (strengths and weaknesses) and external factors (threats and opportunities) of this tissue have been considered comprehensively. The results of this study show that strategies for rehabilitation and renovation of Ab-Anbar-No district are one part of the guidance, control and planning system of urban rehabilitation and modernization, as a guide for decision-making. The considered limitation of weakness and strengths in physical, environmental and functional fields have a high vulnerability and also have optimization opportunities in the economic, social and legal-administrative fields in order to take advantages for reaching perfection.
Rehabilitation Renovation Worn-Out Texture Ab-Anbar-No District SOWT1. Introduction
City is an intertwined structure that many institutions and individuals are involved in the formation of social life and its facade. By reviewing cities expansion and civic and social interaction, they have getting changes, evolution, growth, and development over the time as well as other human artifact. This development is a dynamic and continuous process which during it the city physical limits and physical spaces change in vertical and horizontal directions as to increasing quantitative and qualitative terms and if this trend is rapid and unplanned, physical formation of urban spaces will not be appropriate. Consequently, urban system will face serious problems [1] . Iran cities due to the increasing population, are physically extending continuously that are often horizontally and occupy extensive their surrounding areas. During the time, and ownership changing in urban central texture, they will suffer physical quality and get exhaustion. The worn areas in cities are four types as follows: 1) textures with a historical and urban heritage; 2) urban areas (non-historical); 3) fringe areas (informal settlements); 4) inefficient tissues [2] . These cities are need to their worn tissues to survive. Generally, the belief to improve the environment is one of the sources of the special idea for urban planning and perhaps the most important ideology that is consistent [3] .
(Urban historical texture) refers to those legal urban areas that because of physical worn, lack of suitable availability for cavalry, facilities, services and urban infrastructure are vulnerable and they have low economic, environmental and local values [4] .
The term renovation and rehabilitation generally means a change of urban environment in order to organize urban problems [5] . Renovation and rehabilitation of urban historical contexts has always been important not only to protect the historic towns and cultural monuments, but also to respond to urban needs and caused repairing old damage and damage on building and new operation adapted by needs of life [6] . Their purpose is to improve the quality of life in worn tissue [7] . On the other hand, the different politics of modernization in different countries and epochs has had effective worthy results in development of urban renewal [8] . Thus, a first step in renovation of worn-out texture is their identification and prioritization to intervene and determine the type of intervention and investment. In this texture, lack of proper and correct identification and prioritization of this texture will result inefficient modernization programs and wasting resources and capital, and the subsequent expansion of the wear in the urban fabric [9] .
Sari Ab-Anbar-No district is made of appropriate grading in the form of volumes free on the non-geometric space like other urban historical texture, as the private spaces around them are moving around the spaces and create a continuous space that makes it possible for texture to utilize of green and out-door spaces. However, new interventions cause confusion in the past organization. Even though surrounding parts of Ab-Anbar-No passing is still generally retaining their quality, but new construction has created difficulties in that area. Most estate parts are for small components belonging to the different people and most of the residential and commercial estate parts are less than 200 square meters, or between 200 to 250 square meters and usually are private estate [10] . So, this research has modified to review and assess the policies of renovation and rehabilitation urban tissue with an emphasis on Sari city. In this record, the research framework is in order to respond to the ques- tions follows:
―How much of capacity and capabilities of a.a.no storage areas had been appropriate for rehabilitation and renovation to restore and create vitality to the historic fabric?
―How much of the current state of Ab-Anbar-No district had faced with constrains and impasses for rehabilitation and renovation to restore and create vitality to the historic fabric?
Considered assumptions are on the basis to achieve a pattern of create urban vibrant spaces in the old texture and furthermore vitality factors, conditions of environmental configuration must be in good conditions.
2. The Importance and Necessity of Research
The need for restoration and repair of old and valuable historical texture has considered stimulating physical, social, and economic texture and the old area. Parts of the city lose their former growth and, the texture gradually discharged from the indigenous population because of population growth and uncontrolled urban development, and lack of services to older tissue, and replaced with the immigrant population it, over the time. one of issues that cause attention to problems related to old and worn-out texture, is the use of inexpensive and out- dated materials in most of old buildings of the tissue, which is a serious threat to the safety of residents at the of events of natural disasters. This problem doubled up the necessity of reformation and modernization and equipping worn settlements [11] .
disarrangement between scale and physical capacity of old texture with today pattern is most important reason of evacuation, and lack of proper access to cavalry within the texture and the subsequent problems of service, instability and the use of inappropriate materials in new construction and the poor quality of infrastructure facilities and installation are important factor. So if the orientation and direction of the worn-out tissue followed by interventions without the program. These tissues have increased problems day by day and they become turbulent places. So deliberation is essential for these problems.
3. Research Objectives
Strategic planning is one of the pillars of redevelopment and improvement programs. Proper comprehension and precise use of planning and strategic tool for development of strategic planning makes it possible to access the redevelopment and improvement programs [12] . So, in this article we have tried to develop and improved Ab- Anbar-No districts again using the proper and precise tools and updated programs is considered.
What Is the Necessity of Research and the Statement of the Problem as Objectives of This Article Are Following?
1) Rehabilitation and vitality in old and historical texture.
2) Facilitating accessibility as the most important factor in the dynamics and services to old textures.
3) Improving performance with respect to the living body.
4) The physical rehabilitation with people coordination.
In addition, it should be noted that this district Ab-Anbar-No, include its accessory spaces and valuable buildings, is the part of old the city center. That any construction changes in it demands its own legitimacy.
4. Research Method
The purpose of this research, is applied-studious and its essence and method is studious analytical-descriptive. In this descriptive-analytical research, the current status of the texture is studied for understanding the subject. The methods used to collect data, are obtained through library research and use of documents and field data, preparing a questionnaire to record information. The statistic population of study was university professors and experts and scholars in architecture which uses a questionnaire of 30 samples were direct Question-ing.
By documentary and by visiting professors of architecture and gaining information, a questionnaire was developed that in each of the specified internal and external factors in the questionnaire get a coefficient (from 1: Very low to 5 Very high ) and so we ranked any of the factors or parameters from 1 to 5 based on their value in terms of architectural experts rating and we defined their coefficient (Rj) and then by accomplishing the questionnaires by the subjects target population of 30 people, parts of defects was eliminated. The SWOT technique is used to provide practical solutions. In this method of valuation and scoring the internal strengths and weaknesses and the opportunities and external threats, suitable strategies have been proposed for renovation and modernization [13] .
5. Introduction of Research Limitation
Ab-Anbar-No district was one of five old Sari district. This district is located in the central area of the Sari city. This area is limited by the Qaran streets from the south, Farhang street from east and 18 D from North and Enqelab street from West, with the pottage of 96/18 hectare, housed a population with 2271 people, with gross density equal 120 people. New residential buildings and public face of the field in the form of old houses. Access to this area through narrow passages with low quality asphalt, is provided. This area, as well as other areas of the city’s area is a residential area with commercial applications and business services can be seen at the urban scale. Part of the fabric of this area to preserve its ancient skeletal system, the value of the Iranian city.
The old residents of this area are shopkeepers, all of the residents are mostly sari. However, about 5 percent of current residents and residents of surrounding villages constitute the workers and employees and shopkeepers are busy with average income levels. Most dwellings are living in their residential property owners, but tenants are also present in units of 2 or more floors, about 30 percent of residents have formed tissue, see Picture 1 [14] .
Picture 1. Ab-Anbar-No limitation in sari [14] .
6. Study of Effects of Rehabilitation and Renovation Projects Using the SWOT Matrix
SWOT model consists of the first four words of English letters with the Persian Equivalent strengths, weaknesses, opportunities, and threats. This equivalent (strengths, weaknesses, opportunities and threats) is the best strategy for the planning process [15] . And is one of efficient models of strategic management [16] . This technique is a support tool for decision-making that are commonly used to systematically analyze the internal and external environment of organization or city. By defining strengths and weaknesses and the opportunities and threats, the organization or the city can adopt strategies to reinforce the strengths and eliminate the weaknesses and can use the opportunities to counter threats [17] . In this study the characteristics of social, economic, physical-performance, environmental-communicative and administration of ancient texture of Ab-Anbar-No district in Sari have been analyzed using SOWT techniques based on quantitative and qualitative data that to lead organize and future planning strategies in the direction of the strategically strategies objectives of the revive the old structure of the Sari city.
The SWOT method is a qualitative approach. However, in this study it have been tried to quantify the method to achieve stronger results and have been used “Delphi technique” to utilize experts [18] . This technique uses a special table that enable regular and systematic classification of internal and external environment, and using elements of this table, study provides realistic and proper strategies in direction of city development [19] .
6.1. Internal and External Strategic Assessment
Internal and external strategic evaluation causes decision makers and assessment planners to apply the quantitative stage in the development trend of strategic objectives and strategies [20] . The analysis that is done about the relative importance of internal and external factors of Ab-Anbar-No district in Sari, makes it possible that provide different strategic objectives and strategies by effective manner, see Table 1, Table 2.

in accordance with factors [22] . The plan mainly includes a large number of standards and their interdependence, it is possible to use the SWOT is not enough. According to the defect analysis SWOT, in order to increase its efficiency, some techniques combined with SWOT [19] . In this study, SWOT factors have been considered by participation of officials and experts on the five options on Likert scale. This scale is compound. Options in this scale determine their importance. Likert scale has been calculated for each factor to measuring the priority and ranking of internal and external environment SWOT factors, and formulas relative weight between the groups.
Formula 1 Rij= ΣSi・Fi Rij: Points of j from group i (score) Si: Points range of Likert.
Fi: Frequency choices.
Formula 2 Yij: Points of j from group i (weight).
This formula, is one of the methods used to quantify SWOT and provide assessment possibility the relative importance of each groups factors and enable of each and principally assessment of decision-making situation will be combined with SWOT. So SWOT factors set have been designed in the questionnaire form in order to be weighted and prioritized by officials and experts of studied area.
Measurement and classify scale for each of these factors is that for every factor, there is a limitation from 1 to 5 set that number 1 means very low importance, number 2 means low important, the number 3 means average importance, the number 4 means the most important, and number 5 means extremely important factor in the renovation and modernization of the sari’s A.A.N district’s worn-out texture. then gained data’s and information’s have been analyzed and calculated based on total gained weights, mean rank, and their relative weights and have been applied in QUADRUPLET groups to ranking that they are mentioned in above table. So after weighing the four SWOT factors, now the ranking and priority analysis of strengths, weaknesses, opportunities and threats are discussed from the perspective of experts and officials, see Table 4 and Table 5.

valuable architecture construction on the district after renovation and rehabilitation of mansion. The results of this research have the same direction with the acquisition results of numerous researches that considered the role of the revival and vitality of worn-out texture around the country. Hadavi and colleagues (2011) pointed in their article: it is preferred that the implementation of any project in the worn-out texture be quite conservative and based on the model of Conservation and Adaptation and Ravanbakhshi texture, because of the valuable elements [23] .
In addition, Kayani and colleagues (1390) concluded in his research that identity and appearance expression of the city culture emphasize on save them with renovation and rehabilitation. The most important reasons of concerning historical texture are archaeological values and saving identity of place. The main reasons concerning the historical texture, is archaeological value and save the identity of place and identity of this part [24] .

As results of Asadian and Sayyahi research (1390) the low quality of buildings, building materials, narrow streets and passages and lack of Ability to repair and improvement the texture of has been increased problems and they become demolished places [26] . Shamaei and Pourahmad (1383) are believed that one of the factors that led to the recession and sluggish the historical context, is indifference to the Structural repair, and single buildings repair and Lack of relevant extension work, including hull design or repair of streets face without paying attention to living conditions in this textures [27] .
The low motivation of private sector for investment in connection with the restoration of the buildings is impressive. In multiple studies has been mentioned to this issue. Davoud Pour and Nick NIA (1390) expressed that the current transport system have created complex set of urban issues Such as air pollution, erosion, uncontrolled development and social isolation [28] .
