基于强震永久变形动力有限元分析原理的建筑材料再利用,本文采用黏弹性模型--等效非线性化方法对国内某拟建建筑材料回收系统,进行三维强震动力下非线性有限元技术分析,结合有限元子模型技术对回收系统的加速度反应、动位移反应、建筑材料再利用结构的地震永久变形、结构单元的安全系数的分布规律进行精确模拟。
Based on the theory of permanent deformation dynamic deformation finite element analysis of building materials reuse, this paper uses the viscoelastic model - equivalent nonlinear method for a domestic construction materials recovery system proposed three-dimensional strong seismic nonlinear finite element technology Analysis and combined with the finite element model to accurately simulate the acceleration response of the recovery system, the dynamic displacement response, the seismic permanent deformation of the reusable structure of the building materials, and the distribution of the safety factor of the structural elements.
