摘要
轻质混凝土,作为比传统混凝土更为方便的一种选择,在很多土木工程中得到了广泛的应用。通过拟静力试验,对两种不同配筋型式的轻质混凝土剪力墙在低周反复荷载作用下进行了受力性能研究,观测了墙体的整个破坏过程,分析了墙体的强度、变形和抗震性能。试验分析表明,与配有传统横、纵向钢筋网的轻质混凝土剪力墙相比,配有斜向钢筋网的轻质混凝土剪力墙更能有效地传递水平荷载,抑制剪力墙板中裂缝的开展,提高了剪力墙的延性,增强了墙体的整体稳定性,抗震性能较好,能满足地震区的设计要求。
Lightweight concrete （LWC） has been used in many civil engineering as a very convenient ahemative to conventional concrete. Quasi-static test of two lightweight concrete shear walls with reinforcement of different styles were carried out under horizontal low cyclic loading , the whole destroying process of the shear walls was observed, and the properties of strength, deformation and seismic resistance are analysed. The analysis results show that lightweight concrete shear with diagonal web reinforcement transfer shear more efficiently than that with conventional horizontal and vertical web reinforcement, control the development of crack in shear walls, improve the ductility of shear wall, strengthen the integrity of shear wall, and have a good seismic performance.
