【摘要】：高層建筑結(jié)構(gòu)的抗震越來越受到重視。對于高層結(jié)構(gòu)而言，豎向荷載的影響不大，風荷載和地震作用此時占主導地位。尤其是地震作用的突發(fā)性、不定性和破壞性對人類社會危害極大。如何減輕地震作用對結(jié)構(gòu)的傷害，如何減少人類財產(chǎn)和生命安全的損失，這不僅是設(shè)計人員的責任，也是整個人類社會的責任。本文依托于山東臨沂格瑞斯高層剪力墻結(jié)構(gòu)的模擬分析，試圖尋找合理的結(jié)構(gòu)布置并對抗震展開深入研究，主要工作內(nèi)容及研究成果總結(jié)如下： ①通過歸納傳統(tǒng)抗震設(shè)計思想，提出傳統(tǒng)抗震設(shè)計理論的不足之處，進而引出基于性能的抗震設(shè)計理論。并介紹了基于性能的抗震設(shè)計基本內(nèi)容和思想理論，并以PKPM結(jié)構(gòu)設(shè)計軟件為手段分析抗震； ②以山東格瑞斯小鎮(zhèn)為工程實例，進行性能抗震理論設(shè)計。本文從三種模型入手，根據(jù)剪力墻結(jié)構(gòu)布置原則在結(jié)構(gòu)設(shè)置上有所不同，對實際工程進行調(diào)整剪力墻的剛度，厚度，混凝土的材料標號入手，，進行軟件分析從質(zhì)量中心、剛度中心、剛重比、自振周期、剪重比、有效質(zhì)量系數(shù)等方面進行數(shù)據(jù)比較，得到較為合理的分析模型； ③從上步分析得出的合理的分析模型入手，對文中高層剪力墻結(jié)構(gòu)基于性能的抗震分析，通過彈性時程分析和彈塑性時程分析對結(jié)構(gòu)進行抗震分析，并根據(jù)模型數(shù)據(jù)分析，對于層間位移和層間位移角的分析比較，抗震分析均滿足規(guī)范規(guī)定的限值。以振型分解反應(yīng)譜法得出的數(shù)據(jù)為基礎(chǔ)，并以彈性時程分析和彈塑性時程分析的數(shù)據(jù)為補充，獲得合理的結(jié)構(gòu)抗震性能目標。
[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.
