Pushover Analysis of Bearing Wall System with Macroscopic Models - For Comparisons of 2D and 3D Analysis Modelling

거시적 모델을 이용한 내력벽 시스템의 Pushover 해석 - 2차원과 3차원 해석 모델링의 비교

To study the effect of the macroscopic TVLEM(Three Vertical Line Element Model) which is developed in 2D, a bearing wall system is selected and 2D and 3D pushover analyses are carried out. In 2D model, the participating width of a flage wall to lateral resistance is modelled based on Paulay's effective width. From the comparisons of roof displacements, 2D model which uses the effective width of flange wall has better prediction and less analysis time than 3D model which has intrinsically the full width of the flange that causes higher stiffness and strength and shorter deformation capacity than 2D model.
