刍议建筑抗震设计

刍议建筑抗震设计刍议建筑抗震设计 摘要:随着近些年来地震越来越频繁的在世界各地发生,高层建筑的抗震性能逐渐成为广阔人们群众所关注的重点,当高层建筑的抗震性能好了,居住的居民才能住的安心、放心,因此高层建筑的抗震设计也逐步成为当代建筑设计和施工的重点工作, 文中分析了建筑设计在抗震设计当中存在的问题，总结了震害多发点及高层建筑抗震概念设计的基本要点，并对高层建筑的抗震计算方法进行了探讨，最后对加固薄弱环节和结构隔震与消震设计进行浅析。 关键词：高层建筑;抗震设计;消震设计 Abstract: In recent years, the earthquake is more and more frequent in the world, the seismic performance of high-rise buildings gradually become the focus of concern to the broad masses of the people, when the seismic performance of high-rise building is good, the residents can live at ease, rest assured, so the seismic design of high-rise building has gradually become the focus of the work of design and construction construction, the analysis of the architectural design in aseismic design, summarized the seismic damage and seismic concept design of high-rise buildings and the basic points, and of a high-rise building seismic calculation method are discussed, finally analyze the strengthening weak links and structure vibration isolation and shock absorption design. Key words: high-rise building; seismic design; seismic design 中图分类号：[TU208.3] 文献标识码：文章编号： 引言： 现在社会快速进展，城市里不断兴建越来越高的建筑，就对我们的高层设计不断提出了更高的要求，工程师按抗震设计法律规范要求进行结构分析与设计，其目标是希望使所设计的结构在强度、刚度、延性及耗能能力等方面达到最佳，从而经济的实现“小震不坏，中震可修，大震不倒”的目的。但是，由于地震作用是一种随机性很强的循环、往复荷载，地震的破坏机理又十分复杂，存在着许多模糊和不确定因素，在结构内力分析方面，由于未能充分考虑结构的空间作用，非弹性性质、材料时效、阻尼变化等多种因素，计算方面还很不完善，单靠微观的数学力学计算还很难...
