钢筋混凝土框架结构的抗震设计要点汇总摘要: 地震灾害具突发性,至今可预见性仍很低,给人类社会造成损失严重是各类自然灾害中最严重的灾害之一。根据我和经济条件, 对建筑抗震提出了三个水准的设防目标,即通常所说的“小震不坏,中震可修,大震不倒”。钢筋混凝土框架结构是地震设防区常见的建筑结构形式,在工业和民用建筑中应用广泛,由于结构本身的力学特点,抗震‘性能较差。通过加强技术措施, 挖掘材料潜力, 可以得到有效改善。针对框架结构设计中常见的一些问题进行了分析,提出了设计中注意的要点。 ABSTRACT With a sudden earthquake disaster, has predictability is very low, to human society caused serious loss is one of the most serious disasters of all kinds of natural disasters. According to the current scientific level and ondition, put forward three levels of fortification goal for seismic design of buildings, which is usually called "minor earthquake, repairable under moderate earthquake, earthquake does not fall". Reinforced concrete frame structure mon building}structure form, widely used in the industry andcivil architecture, due to the characteristics of the mechanical, have the poorer anti-seismic to strengthening the technical measures, excavate materials potential, it can be improve effectively. Analyze to some problems according to the structural design mon framework, to bringforward the key point of the design. 关键字混凝土结构框架结构结构抗震结构设计 KEY WORDS Concrete Structure, Frame Structure, Structural Seismic, Structure Design 钢筋混凝土框架结构是我国多高层建筑中最常用的结构形式,广泛用于地震设防区,在合理的设计下具有良好的抗震性,所以以框架结构为例来阐述混凝土的抗震设计。 1. 结构延性在抗震中的重要性及作用结构抗震的本质就是延性, 延性是结构, 构件或构件的某个截面从屈服开始到达最大承载能力或到达以后而承载能力还没有明显下降期间的变形能力,是结构抗震能力强弱的标志。今天已有本身延性非常好
