摘要
采用大型通用有限元软件ANSYS10.0分别建立考虑地基基础共同作用与刚性地基下的框架-剪力墙结构有限元模型,通过对两模型的模态分析与地震响应时程分析,可以得到两模型下的固有频率及上部结构的内力、应力、变形,并对它们进行对比分析。分析比较可知:刚性地基下,结构的动力特性较好,具有良好的自振特性;考虑共同作用,结构的内力、应力、变形较刚性地基下大。实际工程中应考虑地基基础与上部结构的相互影响,使结构安全、适用、经济。
according to the design specification,using large general finite element software,ANSYS10.0 based and rigid respectively established under the consideration of the foundation with frame-shear wall structure finite element model of two model,through the modal analysis and seismic time history analysis,can have two model under the inherent frequency and the upper structure of internal force,stress,deformation,and they are compared and analyzed.The comparative analysis,structure,rigid foundation of the dynamic properties is good,has the good vibration characteristics;Consider common function,the structure of the internal force,stress and deformation under a finite element model of rigid foundation.In practical engineering foundation should be considered,avoid does not consider the role of the negative influence of joint action,make structure do do safety,applicability,economy.
