  1. A Study on the 3-Point Bending Test and Mechanical Behavior of the Hybrid FRP BeamYeou-Fong Li1and Tai-Cheng Chen 1Professor of the Department of Civil Engineering , NTUT, Taipei, Taiwan . 2 Master of the Department of Civil Engineering, NTUT, Taipei, Taiwan. • Boundary Conditions of Shear Wall Analysis • Constitutive Law of Concrete and Steel Keywords：Finite Element Method, Shear Walls, Crack Distribution Abstract : Reinforced Concrete (RC) shear wall in structure system can provide lateral stiffness and be applied to the structural reinforcement project. The main factors to affect the mechanical behavior of the RC shear wall include the steel ratio, the ratio of height to width, and the wall thickness. Therefore, the study is to evaluate the past literature and the nonlinear pushover analysis of RC shear wall by the Finite Element Method of ANSYS software. The specimens include three types of RC shear wall (in high, medium and low mode), framed shear walls with opening. By changing the steel ratio, the ratio of height to width and the wall thickness, the nonlinear pushover analysis is conducted for evaluation. After reviewing the analysis and comparing the results with the past literature, the trends of the force-displacement curve and the crack distribution in the wall are similar to the experimental results. Steel Concrete • Cracking Distribution and Evolution • Force-Displacement Relationship of Change The Ratio of Vertical Reinforcement • Conclusions The increase of the steel ratio of RC shear wall leads to the increase of the wall strength as well as the cracks distribution scope. The increase of the thickness of RC shear wall leads to the slight increase of the wall strength, but the decrease of the cracks distribution scope. The increase of the ratio of height to width of RC shear wall causes the decrease of the wall strength. To increase the thickness of RC shear wall with opening will lead to the increase of the wall strength, but no effect on the cracks distribution.
