木柱梁-土坯组合墙体非线性数值计算分析

对3种不同厚度的素土坯墙体和3种不同厚度的木柱梁土坯组合墙体进行了有限元弹塑性计算.通过计算分析了素土坯墙体和组合墙体抗侧承载力、裂缝形态、延性.在此基础上,提出了墙体的抗侧承载力的简化计算公式,为木柱梁-土坯组合墙体设计提供了依据.同时,对素土坯墙体和木柱梁-土坯组合墙体在不同烈度地震作用下(众遇烈度、基本烈度和罕遇烈度)的效应进行了评估.研究表明,传统的素土坯墙体通过木柱梁形成组合墙体,可以满足9度地区罕遇地震烈度下裂而不倒的设防准则,研究结果可作为新疆传统生土民居的改造及抗震加固的依据.

Finite element nonlinear numerical analysis and shear resistance of timber column and beam adobe composite wall

We calculated the elastic-plastic finite element method(FEM) of three adobe walls and three composite adobe walls of differing thicknesses,and analyzed their lateral resistance capacities,crack shapes and ductility.Based on the results,a simplified formula is put forward for calculating the lateral resistance capacities of composite adobe walls.The formula provides a basis for designing composite adobe walls.In addition,we estimated the seismic effects of earthquakes of varying degrees and frequency of inte...
