摘　　要：以新疆大学博达校区图书馆为背景工程,选取结构中一大跨度钢梁进行施工期间的现场实测及定性、定量分析。从施工中温度作用对结构安全性影响与结构构件对温度作用敏感程度两方面入手,采用有限元软件MIDAS/Civil进行温度效应分析。通过对7种荷载工况进行数值模拟得出:温度作用对结构应力影响较大,构件对于升温作用的敏感程度要大于降温作用的敏感程度;并通过引入温度应力响应程度这一参数进行了定量分析。最后通过对比数值模拟与实测数据处理得到的温度线性系数验证了有限元分析方法的准确性,并通过相关性分析验证了实测数据处理方法的可行性。In this paper,taking the library of Boda Campus of Xinjiang University as the background project,a large span steel beam was selected for on-site measurement,qualitative and quantitative analysis during construction.MIDAS/Civil is used to analyze the temperature effect from two aspects:the influence of temperature action on structure safety and the sensitivity of structural components to temperature action.Through the numerical simulation of seven load cases,it is concluded that the temperature effect has a great influence on the structural stress,and the sensitivity of members to the temperature rise effect is greater than the temperature drop effect;The quantitative analysis is carried out by introducing the parameter of temperature stress response degree.Finally,the accuracy of the finite element analysis method is verified by comparing the temperature linear coefficients obtained from the numerical simulation and the measured data processing,and the feasibility of the measured data processing method is verified by correlation analysis.
