某高层建筑的转换梁设计为钢桁架,考虑到转换钢桁架的重要性,对转换钢桁架进行了施工监测,主要监测其各个施工阶段的沉降、挠度以及关键位置的截面应力情况。用Midas/Gen建立该建筑的整体模型,进行对应的施工阶段分析。将监测结果与理论计算进行了比较,结果表明实际监测值与理论计算值吻合较好,变化趋势基本一致。本文深入分析了实测数据与理论计算数据存在偏差的原因,可供类似工程参考。 The conversion girder of a high-rise building is designed as a steel truss. Considering the importance of the steel truss conversion, the construction of the conversion steel truss is monitored. The settlement, deflection and cross-section stress of the key positions are mainly monitored. Use Midas / Gen to build the overall model of the building and analyze the corresponding construction phases. The results of monitoring and theoretical calculations are compared. The results show that the actual monitoring values ​​are in good agreement with the theoretical ones and the changing trends are basically the same. This paper analyzes in-depth analysis of the measured data and the theoretical calculation of the reasons for the deviation, for similar projects for reference.
