【摘要】 有时砌体承重墙上开有洞口,计算承载力时,一般不考虑洞口对墙体强度的影响,对于较窄墙肢墙体压应力可能很大,结构偏向不安全。本文通过弹性有限元分析,对开有洞口墙体应力进行了分析,推导出开洞墙体中窄墙肢的应力计算公式,对砌体结构房屋的设计具有重要的意义。更多还原

【Abstract】 Sometimes hole is maked in a masonry structure,intensity influence because of the hole is not considerated,which make the structure dangerous.This article completes to calculate the stress in wall bottom with FE software,researching the factors of influencing bearing capacity deeply.A calculation formula about the influence on the basis of these is proposed,which is significant for the design of masonry structural buildings.更多还原
