摘要
通过对5.12汶川地震框架结构中板式楼梯的破坏现状的调查,从结构设计、材料选用,施工技术措施等方面提出导致楼梯破坏的原因。使用SATWE和ETABS软件分析考虑梯板斜撑作用后对结构整体工作性能及内力的改变,根据计算结果和工程经验,提出改善楼梯工作性能的施工措施和设计措施。
This paper points out factors causing staircase destruction on the aspects of structural design, material selection and construction technique, through survey on status quo of cranked slab stairs in frame structure destroyed in ＂May-12th Wenchuan Earthquake＂. SATWE and ETABS software are adopted to analyze changes of integral working performance and internal force of structure after consideration of oblique bracing of stair tread. Construction and design measures are proposed to improve working performance of staircase accord- ing to the calculated results and engineering experiences.
