EFFECT OF FLEXURAL STIFFNESS OF END BEAM ON THE FAILURE BEHAVIOR OF STEEL SHEAR WALLS UNDER CYCLIC LOADING
Steel plate shear walls are known as suitable systems for resisting lateral loads. In the last few decades, they have been used in the construction of new buildings and retrofit of existing buildings. In this paper, the behavior of a true-scale, single-bay single-story panel was investigated through a three-dimensional nonlinear finite element analysis. The finite element models include a steel shear wall with different end beams. For the loading (displacement) time history, the ATC-24 guidelines have been used. This loading has applied to the top nodes of the beams. Various parameters such as initial stiffness, strength, and energy absorption were obtained and the effect of the flexural stiffness of the end beam on these parameters was investigated and discussed. The results show that the cyclic behavior of steel shear walls is affected by the stiffness of the end beam. If this stiffness is low, the diagonal tension field cannot be performed properly. Therefore the ductility and energy absorption capacity of the panel is reduced.
