摘　　要：以六榀轻骨料作为混凝土建筑材料对剪力墙进行了抗震性能方面的研究。采用有限元软件ANSYS构建了轻骨料混凝土剪力墙非线性有限元模型,构成模型的滞回曲线与试验滞回曲线完全吻合,由此通过试验的方法可以解决无法准确模拟轻骨料混凝土力学性能的问题。在此基础上,通过试验分析了该轻骨料混凝土剪力墙在抗震性能方面的主要影响因素,为建筑工作者在实际工作中进行更好的建筑设计提供了指导。Six common lightweight aggregates are chosen as the concrete materials to investigate the anti-vibration performance of the shear wall.Software ANSYS is employed to construct nonlinear finite element model of the lightweight aggregate concrete shear wall.Results show that the hysteresis curve obtained by the finite element model is in excellent agreement with the experimental hysteresis curve,which verifies that this method can effectively deal with practical engineering problems.On this basis,the main factors and their influences on the seismic performance of the lightweight aggregate concrete shear wall are analyzed by experiment.This research may provide the guidance to construction worker for better practical architectural design.
