【正文】 mate the seismic demands of structures, considering the redistribution of inertia is suggested that after establishing the idealized bilinear curve, a pushover analysis is once again conducted for the first mode in two phases: before and after the structure the two phases, the structural elastic natural mode and the floor displacement vector at the initial yielding point are used as the displacement shape vector, approximately estimating method of displacement of reinforced concrete(RC)frame from static pushover analysis(POA)is developed with that from nonlinear response history analysis(RHA).Based on the statistic analyses of the RHA and POA results for five RC frames with different height under 80 ground motions recorded at four site conditions, the revised formula of displacements from POA is presented from results show that the site soil condition has an important effect on the relation between RHA and POA response the POA results for I and IV site condition should be revised with the formula given in this study while the POA results for II and III site condition can be approximately considered as same to the RHA RHA under 15 ground motions recorded on the medium site condition and POA with different lateral load patterns are performed for four RC structures with different important response quantities are obtained from the RHA and POA, including capacity curves, top displacement ratios and story drift ratios, and location of plastic influence of different load patterns on the structural performance demands is discussed for the lowand the highwise the rational load patterns for the lowand the highwise structures are also simple procedure is presented in this paper for estimating hysteretic energy demands of MDOF systems based on the modal pushover analysis(MPA).Firstly, the characteristic parameters of the modal SDOF systems of structures are puted, and the hysteretic energy is calculated for the modal SDOF systems, then the hysteretic energy demand of structures is obtained by bining these modal addition, with statistic results of nonlinear analysis of SDOF for 320 ground motions recorded at four site conditions, the equalstrength hysteretic energy design spectra are presented for different site condition and intensity words: pushover analysis procedure, capacity spectrum method, themodal pushover analysis, lateral load patterns, hystereticenergy第三篇：論文中英文摘要摘要隨著信息時(shí)代的到來，信息高速公路的興起，全球信息化進(jìn)入了一個(gè)新的發(fā)展時(shí)期。首先采用模態(tài)Pushover分析計(jì)算結(jié)構(gòu)各階模態(tài)單自由度體系的特征參數(shù)，然后計(jì)算結(jié)構(gòu)各階模態(tài)單自由度體系對(duì)應(yīng)的滯回耗能，并將其進(jìn)行線性組合進(jìn)而確定結(jié)構(gòu)的滯回耗能，并與結(jié)構(gòu)通過動(dòng)力時(shí)程分析計(jì)算得到的滯回耗能進(jìn)行比較，從而給出一種物理概念簡(jiǎn)單、計(jì)算操作方便的確定結(jié)構(gòu)滯回耗能的方法。，分別進(jìn)行了中等硬度場(chǎng)地上15條地震動(dòng)作用下的非
