摘要
由于地震灾害的频繁发生,钢筋混凝土结构经常在地震中遭到严重破坏。为明确地震震级及地震类型对钢筋混凝土框架结构的影响,利用有限元分析软件ABAQUS建立了6层钢筋混凝土框架结构模型,分别计算其在6度、7度、8度地震作用下的动力响应以及结构在不同类型地震作用下被破坏的情况。研究发现,地震过程中结构的破坏会导致结构加速度响应数值的减小,近场地震作用下结构层数变化导致的动力响应变化较大,远场地震作用下结构非线性发展更快,消耗能量更多,结构被破坏也越严重。
Due to the frequent occurrence of earthquake disasters,reinforced concrete structures are often seriously damaged in earthquakes.In order to clarify the influence of earthquake magnitude and earthquake type on reinforced concrete frame structure,a six story RC frame structure model was established by using finite element analysis software(ABAQUS),and its dynamic response and failure under 6,7 and 8 earthquakes and the failure of structure under different types of earthquakes are calculated respectively.It is found that the damage of the structure during the earthquake will reduce the value of the acceleration response of the structure.The dynamic response changes greatly due to the change of the number of layers of the structure under the near-field earthquake.The nonlinear development of the structure under the far-field earthquake is faster,the energy consumption is more,and the structural damage is more serious.
