摘要
本文以某大剧院多功能厅钢桁架结构马道为背景,对该马道进行了静载试验研究。由于是新建结构,对其正常使用存在不确定性,所以用单调加载静力试验来研究其承载力和稳定性。通过静载试验得到马道最大跨主要受力杆件的应变大小以及最大跨挠度大小等重要数据,然后使用有限元软件ABAQUS进行了建模分析,由此也进一步的验证出检测数据的可靠性。有了这一分析过程也将为现实工程结构静载试验检测鉴定提供参考。
In this paper, the background is the steel truss structural bridleway of multi-function hall in a grand theatre,which has been carried out the static load test.Because of the new structure,there is uncertainty about its normal usage, so the load-bearing capacity and stability are studied by monotone loading static test.The strain of the main force-bearing bars and the biggest span deflection and other important data are obtained across the static load test of the bridleway,then analyzes modeling using finite element software-ABAQUS, which could further verify the reliability of the testing data.This analysis will also provide a reference for the test evaluation of the static load test.
