Numerical nonlinear analysis of composite shear walls usingfiber element method

The use of common reinforced concrete shear walls in high rise buildings is sometimeslimited because of the large amount of reinforcement localized at the end of the element. Agood alternative solution in avoiding this disadvantage is to use composite steel reinforcedconcrete shear walls (CSRCW) with steel encased profiles. This solution used for high risebuildings, offers to designers lateral stiffness, shear capacity and high bending resistingmoment of the structural walls with even better behavior in cyclic loads like earthquakeloading. This study consist of numerical analysis of 1:3 scale of composite shear wallelements. The aim of this study is to introduce a time-saving and precise method, called fiber element method, for analyzing the walls and to verify the nonlinear behavior of a kind of CSRCWs with three different steel shape encased profiles and a common type of CSRW, then comparing them with each other. To establish the accuracy of the analytical model and experimental results for load-displacement, hysteretic responses are studied for cyclic loading. The OpenSees software is used for modelling the discussed shear walls
