【摘要】：百集龍項目位于云南省昆明市,集商業(yè)、辦公、餐飲于一體。首先根據(jù)建筑高度、建筑平面功能要求對該項目B樓進行超限情況判斷并確定相應(yīng)的性能目標(biāo),并針對不規(guī)則情況、不同的結(jié)構(gòu)部位、重要程度,采取不同的抗震設(shè)計措施。其次,通過SATWE、YJK兩種軟件對該樓進行多遇地震下的計算分析并對計算結(jié)果進行比較,以確定計算結(jié)果合理、有效,計算模型符合結(jié)構(gòu)的實際工作狀況。通過對比可知,周期、位移、剪重比、軸壓比等均滿足規(guī)范要求。再次,采用YJK程序?qū)Y(jié)構(gòu)進行多遇地震下的彈性時程分析,將彈性時程分析結(jié)果與CQC計算結(jié)果進行比較,通過對比可知其結(jié)果滿足規(guī)范要求。最后,采用多層及高層建筑結(jié)構(gòu)彈塑性靜動力分析軟件EPDA進行彈塑性靜力Pushover分析,以確保該結(jié)構(gòu)滿足"大震不倒"的要求。
[Abstract]:Baijilong project is located in Kunming, Yunnan Province, which integrates business, office and catering. Firstly, according to the height of the building and the functional requirements of the building plane, the over-limit situation of the B building of the project is judged and the corresponding performance objectives are determined, and different seismic design measures are taken according to the irregular situation, the different structural position and the importance degree. Secondly, the calculation and analysis of the building under frequent earthquakes are carried out through two kinds of SATWE,YJK software, and the calculation results are compared to determine that the calculation results are reasonable and effective, and the calculation model accords with the actual working condition of the structure. By comparison, it can be seen that the period, displacement, shear weight ratio and axial compression ratio all meet the requirements of the specification. Thirdly, the elastic time-history analysis of structures under frequent earthquakes is carried out by using YJK program. The results of elastic time-history analysis are compared with the results of CQC calculation, and the results meet the requirements of the specifications. Finally, the elastoplastic static Pushover analysis of multi-story and high-rise building structures is carried out by using the elastoplastic static and dynamic analysis software EPDA to ensure that the structure can meet the requirements of "strong earthquake does not collapse".
