扣件式脚手架的稳定承载性能与现场监测

Stable bearing capacity analysis of fastener-style steel pipe scaffolding systems and monitoring

以合肥市渡江战役纪念馆工程为背景,采用理论分析、数值模拟计算和原位监测相结合的方法,对超高超大悬挑梁模板支架结构体系进行研究,结合安全管理经验,提出对高大模板支架结构动态监测方法修正后试验方案.建立架体三维有限元模型,对其稳定性进行有限元数值模拟分析和试验,并对安全性进行判定.

Based on the crossing campaign memorial project in Hefei,this paper gives an analysis of the ultra large cantiever beam template support falsework system by adoption theoretical analysis, and numeri cal mock calculation,and combined with the research method of in-situ testing and safety management experience. The experimental scheme was in troduced by modifying the dynamic monitoring measurement method in the code for steel tube scaffold couplers. A 32 D FEM was established to simulate the whole falsework and the safty characteristics wew detemined.
