摘要

摘要: 为探究高大模板支撑体系在混凝土浇筑过程中内部杆件的力学响应特征,对西安市某地下会所的高大模板支撑体系进行了内力静态实测。采用有限元计算软件ANSYS以荷载步的形式模拟混凝土的各浇筑阶段,将计算结果同实测结果进行对比。经对比发现:混凝土浇筑顺序直接影响着立杆轴力的变化趋势及轴力峰值出现的位置;采用假想水平力模拟架体初始缺陷对高大模板支撑体系进行整体稳定性分析较为合理。指出了架体搭设方案及混凝土浇筑顺序应结合整架有限元分析加以确定。

Abstract: To explore the characteristics of high support system of formwork during the process of pouring concrete,an underground club in Xi'an was chosen as research object.While pouring concrete,the electrical measuring method was used to measure the stress of steel pipe in high support system and the measured results were compared with the results simulated by finite element analysis software ANSYS.The results showed that the pouring sequence of concrete had a great impact on axial force trends and the location of the maximum axial force.What's more,in the calculation of the overall stability of high support system for formwork,imaginary horizontal force should be used.To improve the security of the formwork support system,the erection program of high support system and the pouring sequence of concrete should be determined based on the analysis of finite element of high support system for formwork.
