混凝土结构墙体广泛应用于高层建筑以提高建筑物的侧向刚度。这种剪力墙结构抵抗风荷载及中等地震是比较好的,结构和非结构部件均不会损坏。在强烈的地震地面运动中,一个结构的反应性能取决于有多少能量输入该结构以及这些能量是怎样被消耗掉的。由于结构的弹性承载能力是有限的,它受材料强度的限制,地震中,结构的耐震一般依赖其延性去耗散地震能量,这就包含了永久性的非弹性变形和某些损坏。一般来讲,刚性结构,诸如有剪力墙的结构会受到较大的惯性力,所以需要较高的强度和延性。钢筋混凝土墙的延性对细部构造和质量控制极为敏感。施工缝的存在以及墙体竖向钢筋搭接全部在楼板水平处,这是引起人们怀疑剪力墙延性的典型问
Concrete structural walls are widely used in high-rise buildings to increase the lateral stiffness of buildings. This type of shear wall structure resists wind loads and moderate earthquakes, and structural and non-structural components are not damaged. In strong earthquake ground motion, the reaction performance of a structure depends on how much energy is input into the structure and how it is consumed. Since the structural elastic load carrying capacity is limited, it is limited by the strength of the material. In an earthquake, the seismic resistance of the structure generally depends on its ductility to dissipate seismic energy. This includes permanent inelastic deformation and some damage. In general, rigid structures, such as those with shear walls, are subject to greater inertial forces and therefore require higher strength and ductility. The ductility of reinforced concrete walls is extremely sensitive to the detailed structure and quality control. The existence of construction joints and the vertical reinforcement of the wall are all at the level of the floor. This is a typical question that arouses people’s doubt about the ductility of the shear wall.
