模拟试验了7片不开洞低矮抗震墙和4片开洞低矮抗震墙,编制了钢筋混凝土有限元全过程分析程序,研究了单调加载及低周反复荷载作用下低矮抗震墙的力-变形性能,揭示了其应力分布、裂缝产生和发展的规律以及周边框架的约束机理等。根据低矮墙的受力机理提出了抗震墙的强度和刚度实用计算公式。
Seven simulations were conducted on the low-shock seismic wall with no openings and four low-rise anti-seismic walls with openings. A full finite element program for the analysis of reinforced concrete was developed to study the forces of low-rise and aseismic walls subjected to monotonic loading and low cyclic loading. - Deformation performance reveals the stress distribution, the law of crack generation and development, and the restraining mechanism of the surrounding frame. According to the force mechanism of low-rise walls, a practical formula for strength and stiffness of seismic walls is proposed.
