从目前发展情况看,村镇钢筋混凝土房屋建造的相对较矮,针对这一特点,本讲重点讲述二层以上,多层以下钢筋混凝土房屋的抗震构造。 一、抗震房屋的延性保证 当地震为中震和大震时,钢筋混凝土房屋的结构构件已进入了弹性受力阶段,构件在保持有一定承载力条件下,主要以弹塑性变形来耗散地震能量,这就要 Judging from the current development situation, the construction of reinforced concrete houses in villages and towns is relatively short. In response to this feature, this lecture focuses on the earthquake-resistant structures of reinforced concrete buildings with more than two stories below. 1. The guarantee of the ductility of earthquake-resistant housing When the earthquake is a moderate earthquake and a large earthquake, the structural members of the reinforced concrete house have entered the stage of elastic stress. Under the condition of maintaining a certain bearing capacity, the components mainly dissipate earthquakes by elastic-plastic deformation. Energy, this is necessary
