【摘要】：高层建筑结构的抗震越来越受到重视。对于高层结构而言，竖向荷载的影响不大，风荷载和地震作用此时占主导地位。尤其是地震作用的突发性、不定性和破坏性对人类社会危害极大。如何减轻地震作用对结构的伤害，如何减少人类财产和生命安全的损失，这不仅是设计人员的责任，也是整个人类社会的责任。本文依托于山东临沂格瑞斯高层剪力墙结构的模拟分析，试图寻找合理的结构布置并对抗震展开深入研究，主要工作内容及研究成果总结如下： ①通过归纳传统抗震设计思想，提出传统抗震设计理论的不足之处，进而引出基于性能的抗震设计理论。并介绍了基于性能的抗震设计基本内容和思想理论，并以PKPM结构设计软件为手段分析抗震； ②以山东格瑞斯小镇为工程实例，进行性能抗震理论设计。本文从三种模型入手，根据剪力墙结构布置原则在结构设置上有所不同，对实际工程进行调整剪力墙的刚度，厚度，混凝土的材料标号入手，，进行软件分析从质量中心、刚度中心、刚重比、自振周期、剪重比、有效质量系数等方面进行数据比较，得到较为合理的分析模型； ③从上步分析得出的合理的分析模型入手，对文中高层剪力墙结构基于性能的抗震分析，通过弹性时程分析和弹塑性时程分析对结构进行抗震分析，并根据模型数据分析，对于层间位移和层间位移角的分析比较，抗震分析均满足规范规定的限值。以振型分解反应谱法得出的数据为基础，并以弹性时程分析和弹塑性时程分析的数据为补充，获得合理的结构抗震性能目标。
[Abstract]:More and more attention has been paid to the earthquake resistance of high-rise building structures. For high-rise structures, vertical loads have little effect, wind load and earthquake action play a dominant role at this time, especially the sudden occurrence of earthquake action. Uncertainty and destruction do great harm to human society. It is not only the responsibility of designers to reduce the damage to structures caused by earthquakes and how to reduce the loss of human property and life safety. It is also the responsibility of the whole human society. This paper is based on the simulation analysis of the high rise shear wall structure in Linyi, Shandong province, and tries to find out the reasonable structure arrangement and carry out in-depth research on the earthquake resistance. The main work and the research results are summarized as follows:. The main contents of this paper are as follows: (1) by summing up the traditional seismic design idea, the deficiency of the traditional seismic design theory is put forward, and then the performance-based seismic design theory is introduced, and the basic content and thought theory of performance-based seismic design are introduced. Using PKPM structural design software as a means to analyze the seismic; (2) taking Grays small town in Shandong province as an engineering example, the theory of seismic performance is designed. In this paper, the stiffness and thickness of shear wall are adjusted according to the structural arrangement principle of shear wall, according to the three models. Starting with the material labeling of concrete, the software analysis is carried out from the aspects of mass center, stiffness center, rigid-weight ratio, natural vibration period, shear weight ratio, effective mass coefficient and so on, and a more reasonable analysis model is obtained. Starting with the reasonable analysis model obtained from the previous analysis, the seismic analysis of high-rise shear wall structures based on performance is carried out through elastic time-history analysis and elastic-plastic time-history analysis, and the seismic analysis is carried out according to the model data. For the analysis and comparison of the interstory displacement and the interstory displacement angle, the seismic analysis meets the limit values stipulated in the code. The seismic analysis is based on the data obtained by the mode decomposition response spectrum method, and is supplemented by the data from the elastic time-history analysis and the elastic-plastic time-history analysis. A reasonable target of seismic performance is obtained.
