摘要
基准选取对网架结构挠度计算影响很大,为了更好的评价网架的设计及施工质量,本文介绍三种不同基准选取方法计算检测挠度。并以工程实例比较计算结果,得出造成不同挠度值的因素,为准确计算网架检测挠度提供参考。
Datum selection has much influence on the deflection calculation. In order to evaluate the truss design and construction quality correctly, the deflection calculation methods using three different datum selections are introduced. Meanwhile, based on the comparison of calculation results of engineering projects, the factors influencing the different results are concluded. It can provide references for the correct deflection calculation of truss inspection.
