【摘要】:地震的发生是小概率事件,但是如果一旦发生将会造成无法挽回的经济损失和严重的人员伤亡。因此把建筑物的抗震设防工作放在首位是每个国家都无法推卸的责任与义务,为了真正提高建筑物的抗震设防等级,世界各国的工程技术人员都在日以继夜的研究抗震理论和试验分析,直到在建筑物中应用隔震技术,才能够真正保证建筑物在地震中不倒塌,从而可以从实际意义上对生命财产安全提供保障。本文就基础隔震的分析作了以下研究:首先对基础隔震技术的发展和应用现状进行论述,表明基础隔震技术在抗震方面的历史悠久以及在现代社会中存在大量运用基础隔震技术的建筑物。并且对隔震技术的原理进行了详尽的描述,其次简单介绍了隔震支座的分类和构造,从而更加说明隔震技术的发展广泛性和实用性。然后描述了基础隔震的原理,推导了 Mewmark法的数值积分过程。最后根据前面的基本原理和分析方法运用大型有限元通用软件ANSYS建立了基础隔震支座的2跨5层的有限元分析模型,对基础隔震混凝土框架结构模型运用大型有限元软件ANSYS进行了在罕遇地震EL-Centro波、天津波、迁安波的时程分析,与传统抗震结构进行对比。最后运用通用有限元软件SAP2000对结构进行了 Pushover分析,简单介绍了能力谱分析方法,同时讨论并且分析了适合于隔震结构体系的Pushover实现方法和侧向力加载模式,通过与非线性时程分析结果的对比,验证该方法的可靠性以及表明Pushover分析方法在抗震分析的有效性。
[Abstract]:The occurrence of earthquake is a small probability event, but if it occurs, it will cause irreparable economic loss and serious casualties. Therefore, it is an unshirkable responsibility and obligation for every country to put the seismic fortification of buildings in the first place. In order to really improve the seismic fortification level of buildings, Engineers and technicians from all over the world are studying seismic theory and experimental analysis day and night, until the application of isolation technology in buildings can truly ensure that buildings do not collapse in the earthquake. Thus, the safety of life and property can be guaranteed in practical sense. In this paper, the analysis of foundation isolation is studied as follows: firstly, the development and application of foundation isolation technology are discussed. The results show that the foundation isolation technology has a long history in earthquake resistance and there are a lot of buildings which use the foundation isolation technology in modern society. The principle of isolation technology is described in detail. Secondly, the classification and structure of isolation support are briefly introduced, so that the development of isolation technology is more extensive and practical. Then the principle of base isolation is described, and the numerical integration process of Mewmark method is deduced. At last, according to the basic principle and analysis method, the finite element analysis model of the base isolation bearing is established by using the large finite element software ANSYS, which is 2-span and 5-story. The time-history analysis of EL-Centro wave, Tianjin wave and Qian'an wave in rare earthquake by using the large-scale finite element software ANSYS is carried out for the concrete frame structure model of foundation isolation, which is compared with the traditional seismic structure. Finally, the Pushover analysis of the structure is carried out by using the universal finite element software SAP2000, and the method of capacity spectrum analysis is briefly introduced. At the same time, the realization method of Pushover and the lateral force loading mode suitable for the isolated structure system are discussed and analyzed. Compared with the results of nonlinear time-history analysis, the reliability of the method is verified and the validity of the Pushover analysis method in seismic analysis is demonstrated.
