Efficient Simulation of RC Shear Walls in High-Rise Buildings Using a Practical Multi-Cross-Line-Model

摘要

This paper presents a novel model for reinforced concrete (RC) shear walls, named as multi-cross line model (MCLM), combining the concepts of micro- and macro-shear wall models by simulating the stress-strain relationships at the material level using a set of concrete or steel bars, and thereof calculating the resultant stresses. The two-dimensional MCLM jointly with the multilayer shell element can simulate the three-dimensional behaviors of the RC shear walls. The proposed model is validated by using three RC shear wall specimens under cyclic loading conditions. Besides, the huge potential for practical use of this model is also illustrated.
