【摘要】：地震是自然界常见的一种灾害,目前的科学技术还无法对地震的发生进行有效的预测,高烈度的地震通常会造成大量的房屋倒塌和人员伤亡,对社会经济造成巨大的损失。传统的抗震设计方法是通过提高建筑物的刚度来抵抗地震力的作用[55],但当遇到罕遇地震的时候,仅仅依靠增加结构的刚度来抵抗地震作用既不经济也不安全。而对建筑采取隔震措施是一种行之有效的抗震手段,不但可以保证结构的整体安全,而且可以避免地震引起的次生灾害,将地震的损失降到最低。随着经济的发展,社会的进步,房屋的安全越来越被人们重视。隔震技术作为抗震新技术,已经广泛应用在实际工程中,《建筑抗震设计规范》(GB50011-2010)已经正式编入了关于基础隔震结构设计的条文,并且隔震建筑的实际效果也已经被大量的强震观察结果所证实,是目前最安全的建筑形式之一,也是提高地震高烈度地区抗震性能的重要手段。本文主要对最常见的隔震方式——橡胶隔震支座进行研究,主要的内容如下:(1)收集有关隔震建筑的研究资料,了解国内外隔震技术的发展情况,了解橡胶支座的力学性能以及隔震结构的计算分析方法,同时研究目前隔震建筑的设计方法以及隔震建筑构造。(2)根据研究的结果,总结出隔震建筑的模型计算方法,并结合实际工程进行验证,同时对设计与施工中存在的一些问题进行探讨。(3)通过云南某小学项目的隔震设计实践,验证本文理论在实践中的可行性,并进行总结整理。本文的研究成果对基础隔震的结构设计的工程应用有一定的理论意义和实用价值。
[Abstract]:Earthquake is a common disaster in nature. At present, science and technology can not effectively predict the occurrence of earthquakes. High intensity earthquakes usually cause a large number of house collapse and casualties. The traditional method of aseismic design is to resist earthquake force by increasing the rigidity of buildings. [55, but when there is a rare earthquake, it is neither economical nor safe to rely on increasing the stiffness of the structure to resist the earthquake. It can not only guarantee the overall safety of the structure, but also avoid the secondary disasters caused by earthquake, and reduce the loss of earthquake to the minimum. With the development of economy, the progress of society. More and more attention is paid to the safety of buildings. As a new seismic technology, isolation technology has been widely used in practical engineering. The Code for aseismic Design of buildings (GB50011-2010) has been formally compiled for the design of base-isolated structures. And the actual effect of isolated buildings has also been confirmed by a large number of strong earthquake observation results, which is one of the safest building forms at present. It is also an important means to improve seismic performance in high seismic intensity areas. This paper mainly studies the most common isolation method-rubber isolation bearing. The main contents are as follows: (1) collect the research data of isolated building, understand the development of isolation technology at home and abroad, understand the mechanical properties of rubber bearing and the calculation and analysis method of isolation structure. At the same time, the design method of isolated building and the structure of isolated building are studied. According to the results of the study, the model calculation method of isolated building is summarized and verified by combining with the actual project. At the same time, some problems in design and construction are discussed.) through the isolated design practice of a primary school project in Yunnan Province, the feasibility of this theory in practice is verified. The research results of this paper have certain theoretical significance and practical value for the engineering application of structural design of foundation isolation.
