Modeling Of Two-Cell Concrete Cores For Investigation Of Reliabality Of Equivalent Column Method

The behavior of shear walls have been the subject of many researches in the recent past. In contrast, only little mention has been made of the shear core walls structures with coupling beams. The key points in this study is to determine whether equivalent column method is precise in solution or not.This research focuses on the modeling of shear core wall with equivalent column method and two dimensional panel elements method. The models examined are models composed of panel elements and models composed of equivalent column in different hand arrangement. These models are compared with one another and with the solution considered accurate, which is the one obtained by using a finite element method consisting of an adequately dense mesh of finite shell. It can be concluded that application of equivalent column method in cores, leads to inaccurate or even unacceptable results .This deficiency can be improved by using flexible rigid links
