Research/Original Article (بدون رتبه معتبر)
Innovative Precast Post-Tensioned Concrete Shear Wall (PPCSW) comprises two columns as boundary elements and a main precast shear wall. Although, there have been some researches about the cyclic behavior of the PPCSWs, the investigation of the effect of openings in this system has been of less interest. The main purpose of this article is to study the effect of a standard opening on the PPCSWs. The numerical models are prepared for three different heights (3,6, and 9 stories) and their cyclic dissipated energy is compared. The concrete damage plasticity model is applied as constitutive material law. The numerical results demonstrate that by increasing the shear wall’s height, the openings become more effective. Therefore, the maximum reduction of dissipated energy belongs to the nine stories shear wall system. And, also the maximum strength reduction due to opening effects is for the nine stories shear wall system. In contrast to the strength and dissipated energy variables, the maximum initial stiffness reduction due to opening effects take place in 3 stories model.
