ABSTRACT: The use of thermal insulation materials in the production of masonry is one of the most effective ways of using green building technology. An evaluation of key design and wall parameters which affect the performance of the self-insulating concrete masonry shear walls (SCMSW) is presented. Numerical models using simplified micro modeling techniques were developed to predict the behavior of the building. Performance is evaluated with respect to predicted load capacities, drift, displacement ductility, plastic hinge length, amount of energy dissipation and value of equivalent hysteretic damping. The FE results by using ABAQUS were also compared to results obtained by an experimental program to gain a better understanding of how the parameters influence wall behavior, and the results were in accordance. It was concluded that the proposed models can be used to deduct the general behavior of grouted specimens. Finally, an example of an eighteen-story building under an earthquake excitation was provided to provide a practical application of self-insulating concrete masonry shear walls.
