ABSTRACT: The use of steel structures in the developing countries is limited in spite of its
better performance in the case of seismic events due to its high ductility. Although
steel structures behave well under seismic excitation, nevertheless the
use of structural steel is limiting these days. This paper aims to address various
parameters related to the capacity design approach involved in the seismic
design of conventional steel structures. Few cases of the early steel structures
construction such as bridges in Pakistan are briefly described. Philosophies
based on the capacity design approach and the importance of conventional
steel lateral load resisting systems with their global mechanisms are provided.
The design procedures of Eurocode 8 for Steel Moment resisting
frames, Concentric cross braced frames and Eccentric braced frames are
given and illustrated. It is believed that the paper will contribute and will be
helpful for the designers, researchers and academicians involve in the study
of lateral load resisting systems for incorporating in the design process.
Since synopsis tables are provided, therefore this will allow a clear understanding
of the capacity design approach for different lateral load resisting
systems.
