试论延性钢筋混凝土框架结构的设计要点及其意义
|
摘要
钢筋混凝土抗震结构不仅要满足强度要求,还必须满足延性要求。建筑结构的延性是保证建筑物在受到地震力、风力等荷载的作用下具有一定的耗能能力、产生可控塑性变形破坏、避免突然脆性破坏的主要条件。文章介绍了框架结构概念设计和延性设计的意义,通过分析多次震害框架结构破坏特点,提出了延性设计的一些思路和方法。
The seismic structure of reinforced concrete meets not only the strength requirements but also the ductility requirements.The ductility of building structures is to ensure that buildings have a certain energy dissipation capacity and deformation to avoid sudden brittle damage in the earthquake and fierce wind.This thesis introduces the significance of frame structure design and ductile design.It also puts forward some ideas and methods of ductile design by analyzing some damaged situations in the earthquakes.
