So far , however , the response spectrum method ( rsm ) adopted as the most important tool by the code is unable to deal with such problems 但目前設(shè)計規(guī)范采用的反應(yīng)譜法不能處理這類問題。時程分析法因計算量很大,亦難在工程中得到普及。
The nonlinear analysis of reinforced concrete shear walls includes static analysis method , time - history analysis method and push - over analysis method 剪力墻結(jié)構(gòu)的非線性分析方法主要有靜力法、動力時程分析法和側(cè)推分析方法(即push - over分析方法) 。
A new method is proposed to study a large - scale power station structure in this paer , which is a time history response analysis method with considering non - linear factors for structure analysis 本文提出一種新的分析方法,即采用地震時程分析法并考慮材料的非線性因素,對某大型水電站廠房結(jié)構(gòu)進行抗震研究。
In view of characteristics of the thick slab , the author suggests using not only the method of the modal decomposition but also time interval analyses and found the moment - shear model 鑒于厚板轉(zhuǎn)換層的受力特性,建議對其除用振型分解法進行計算外,還應(yīng)用時程分析法進行補充計算,提出了層間彎剪的力學模型。
And then , the structure ' s dynamic behavior has been investigated and calculated with spectrum and time - history methods , and obtained the conclusion that time - history method should be employed 接著采用反應(yīng)譜法和時程分析法對該結(jié)構(gòu)進行了動內(nèi)力的計算,得到該結(jié)構(gòu)受預(yù)應(yīng)力索非線性的影響,宜采用時程分析法計算動內(nèi)力的結(jié)論。
Compared with the results of time history analysis , response spectrum theory overestimates the action of earthquake , so that the time history analysis should be adopted besides the response spectrum theory in calculating suspended structure 與時程分析法的結(jié)果比較,表明反應(yīng)譜法高估了地震作用。因此,對懸掛建筑結(jié)構(gòu)除采用反應(yīng)譜法分析外,應(yīng)采用時程分析法補充計算。
The more precise results must be obtained from the time history analysis . the results of the two methods are compared which show that the method of " level - conversion intensity " is reasonable . in addition , some advice and measurements are put forward 本文對這種方法計算的結(jié)果與時程分析法計算的結(jié)果進行了比較,證明了采用“水平換算烈度”方法是合理的,并提出了一些改進的措施。
In the first , the finite element models are rendered to analysis the mechanical performance of the isolation structure . the results of earthquake time history analysis indicate that base isolation structure can effectively reduce the earthquake response of buildings 論文對該隔震結(jié)構(gòu)建立了有限元模型,并用時程分析法分析了橡膠墊隔震結(jié)構(gòu)的受力特點、上部結(jié)構(gòu)的位移反應(yīng)特點等內(nèi)容。
The third , according to code for seismic design of buildings ( gb50011 - 2001 ) , the analysis of r . c . frame structure with special - shaped column is conducted under minor levels of ground motion by means of model analysis method and elastic time - history analysis method 第三,按照抗震規(guī)范( gb50011 - 2001 )的相關(guān)規(guī)定,用振型分解反應(yīng)譜法和彈性動力時程分析法,對鋼筋混凝土異形柱框架結(jié)構(gòu)進行了多遇地震下的計算分析。
