摘要
对某半圆拱砖砌烟道结构计算分析,先根据规范分析抗力及荷载的均值、变异系数,在求定值解的基础上用ANSYS有限元软件进行概率分析,得到了拱顶下缘、拱肩外缘抗拉功能函数概率密度图,以及拱顶下缘、拱肩外缘沿通缝的失效概率。
Calculation and analysis of a semi-circular arched brick flue structure is carried out.First,the average value and variation coefficient of resisting force and load are analyzed according to relevant standards,then probability analysis is made by ANSYS finite element software based on finding the fixed value solution.It has obtained the probability density map of tensile performance function of vault lower edge and spandrel outer edge,as well as the failure probability along the cut-through seams at the vault lower edge and spandrel outer edge.
