| 摘 要： | 钢筋混凝土结构的抗震设防目标，通俗的说法是“小震不坏，中震可修、大震不倒”，具体来说是“三水准设防目标”。三个水准的设防目标是通过两阶段设计来实现的。钢筋混凝土结构抗震设计的基本步骤：把握好抗震概念设计，采取双指标控制条件，使结构和结构构件既满足抗震承载力要求又满足变形要求，同时保证加强抗震构造措施，使结构有足够的结构延性，最终实现“三水准设防”目标。

| Abstract: | The goal of three-level seismic design for reinforced concrete structure,in popular word called "no damage in small earthquake,repairable in moderate earthquake,not collapse in large earthquake",can be implemented in two-step designing process.The basic steps are to grasp the aseismic design concept,to take control of dual-target conditions,to make structure and structural components meet the seismic capacity and deformation requirements,to strengthen ectonic earthquake measures,to make frame have enough st... |
