摘要
针对整浇钢筋混凝土楼盖梁受约束扭转问题,应用SAP90有限元分析程序对100多个算例进行有限元分析,在此基础上与相应杆系模型计算结果进行比较,论证杆系结构分析软件存在的计算误差,给出工程设计实用的整浇钢筋混凝土楼盖梁扭转刚度及扭矩修正计算方法.
In order to study the torsional behavior of cast insite RC floor girder, the typical mechanics models are established and more than 100 examples are precisely calculated using Sap90 solid element in this paper. Comparing the solid elements with the frame element within the Sap90 program, the calculation error existing in frame element structural software is analysed. Furthermore, this paper presents an amendment for the torsion and the torsional rigidity of cast insite RC floor girder of frame element structural analysis software, which can be used as reference in engineering structure design.
