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。 The initial deflection of the floor beams of a project due to the combination of lateral loads and axial pressure due to construction defects. Through the theoretical analysis of the initial defect beam, the formula of the static bearing capacity under the lateral load is deduced, and based on this, the bearing capacity and the normal service performance of the defect beam are judged. It is considered that the beam is not treated without special treatment. It is safe. The analysis process of the defective beam can be used as a reference for similar projects.
