Simulation of Cyclic Behavior for Diagonally Reinforced Concrete Coupling Beams using Accurate Analytical Model

Abstract

Coupled shear wall system is an efficient structural system for tall buildings in view of excellent ductility and energy dissipation properties. The objective of this study is to simulate the cyclic curve of coupling beams using an accurate analytical model that can properly account for cyclic deteriorations in strength and stiffness. For this purpose, a phenomenological model is used as a base model in this study. Parameters for the analytical model was determined using the test results of coupling beams. The analytical model with the values of the parameters is verified by comparing the cyclic curves obtained from analyses and experimental tests.
