Basing on the feature of the structure member, the structure is simplified to a 3-d model consist of space beams and shells, so we can make response spectrum dynamic analysis on the finite-element models . at last nonlinear finite element dynamic analysis was made about the structures . the calculated results reveal the rule of dynamic response about model the and show that the aseismic behaviour and failure mechanism of shear wall structure with src supporting frames and src girder transfer floor is better than that of rc one 在7度多遇和罕遇地震力作用下,通過對振型、側(cè)向位移、傾覆力矩和剪力在給定抗側(cè)力結(jié)構(gòu)間分配的比較,以及對框支柱和剪力墻的地震響應、轉(zhuǎn)換層樓板應力比較等模擬分析,得到型鋼混凝土梁式轉(zhuǎn)換層框支剪力墻結(jié)構(gòu)較鋼筋混凝土梁式轉(zhuǎn)換層框支剪力墻結(jié)構(gòu)抗地震力特性上有較明顯的改善的結(jié)論。
In chapter 4, the model-building principle and calculating method of finite element dynamic analysis for large-sized assembled structure are discussed . the substructure model for hydropower house vibration analysis is established to obtain precise modal of generator floor . the harmonic vibration assumption is adopted to calculate house structure's dynamic response from hydraulic excitation force of hydraulic turbine generator unit 第四章討論了大型組合結(jié)構(gòu)有限元動力分析的建模原則和計算方法,建立水電站廠房振動分析的下部結(jié)構(gòu)模型,對巖灘廠房進行整體模態(tài)分析,較準確地得出發(fā)電機層樓板自振特性;同時引進簡諧振動假定,迸行了機組水力振動作用下的廠房結(jié)構(gòu)的動力響應分析。
