摘要
某工程受横向荷载和轴压共同作用的楼面梁因施工缺陷发生初始挠曲。通过对初始缺陷梁的理论分析,推导横向荷载作用下压弯构件的稳定承载力公式,并以此为依据,对缺陷梁承载力和正常使用性能做出判断,认为不做特殊处理缺陷梁仍是安全的。对缺陷梁的分析处理过程,可供类似工程参考。
Initial deflection of the floor beam of a project by lateral loads and co-axial role occurs because of the construction defects. Based on the analysis of the initial defect of the beam, it is derived a formula for stability bearing capacity of the bending members under lateral loads, and makes a conclusion of the bearing capacity and normal performance of defective beams that the defective beams with no special treatment are still safe. The analysis process of the defective beams can be a reference for similar projects.
