摘要
通过四片不同配筋形式的轻骨料陶粒混凝土剪力墙的低周往复水平荷载试验,研究了钢筋的布置形式和钢筋的级别对轻骨料陶粒混凝土剪力墙抗震性能的影响,包括承载力、刚度、延性、耗能能力等抗震指标。研究结果表明:采用斜向配筋形式的轻骨料陶粒混凝土剪力墙比提高钢筋强度更能有效的提高结构的承载力、变形能力、耗能能力,延缓刚度退化,提高结构的安全储备。
Through the horizontal low cyclic loading tests of different reinforcement form of four pieces of light weight aggregate haydite concreteshear wall, the influences of the layout and the level of the reinforcement on the seismic performance of shear wall are studied, including the bearing capacity, stiffness, ductility and energy dissipation capacity. The results indicate that the diagonal reinforcement forms of light weight aggregate haydite concrete shear wall can more effectively improve the bearing capacity, deformation and energy dissipation capacity of the structure than improv!ng the reinforced strength, delay stiffness degradation, and improve the safety reserves of the structure.
