钢筋混凝土框架结构的抗震延性设计要求
|
摘要
在我国现在的多高层建筑中,钢筋混凝土结构应用最普遍,其中钢筋混凝土框架结构是最常用的结构形式。结构抗震的本质就是延性,提高延性可以增加结构抗震潜力,增强结构抗倒塌能力。为了利用结构的弹塑性变形能力耗散地震能量,减轻地震作用下结构的反应,应将钢筋混凝土框架结构设计成延性框架结构。文章主要阐述了钢筋混凝土框架结构的耗能机理和抗震延性设计的方法。
Reinforced concrete structure is used in multistory and high rise building commonly.The nature of structure anti-earthquake performance is ductility,improving the ductility can strengthen the potentiality of anti-earthquake,increase the ability of anti-collapse.In order to use structure's ability of elastic-plastic deformation to consume the earthquake energy,decrease the reaction in the earthquake,ferroconcrete frame structure should be designed into ductile one.In this paper the energy dissipation mechanism and anti-earthquake ductility design of ferroconcrete frame structure are expounded mainly.
