摘要
针对预应力钢筋混凝土梁体张拉过程中梁体受力性能不宜控制的现状,对某后张有粘结预应力钢筋混凝土屋盖张拉过程的变形和受力进行了施工过程监测、数值模拟和理论计算。通过3种方法的对比分析,全面把握梁体受力性能,验证数值模拟结果,为预应力钢筋混凝土梁体张拉过程的受力性能研究提供了新的方法和途径,同时监测结果可为预应力屋盖结构设计与施工提供依据和参考。
The monitoring and the finite element analysis and the theoretical calculation of the structural performance during prestressing of a post-tension cohesive prestressed concrete roof are carried out. Compared with the results of the three methods, the performance of the beam is found out. The numerical method described in the paper is effect, as the result of the experiment is basically consistent with the finite element analysis. The study can provide important reference for the design and the construction of prestressed concrete roofs.
