为了减小考虑轴向变形的一次加载计算所引起的误差，本文通过对规则框架在节，点集中力（恒载）作用下的分析推导出施工影响系数η，只要将一次加载计算结果（如弯矩、剪力）乘以η值，即可考虑到施工进程的影响。并与逐层加载施工模拟计算及一次加载计算进行分析比较，证明了本文的方法，计算简单，概念明确，精度高。对于按一次加载法设计的框架程序只须做少量的修改，就能做到考虑施工进程对变形和内力的影响。
In order to reduce the error caused by one-time loading calculation considering the axial deformation, this paper derives the construction influence coefficient η by analyzing the regular frame under the action of the knot and point concentrated force (durable load), as long as the calculation result is loaded once (such as The bending moment and shear force are multiplied by the η value to take into account the influence of the construction process. Comparing with the layer-by-layer loading construction simulation calculation and one-time loading calculation, the method of the paper is proved, the calculation is simple, the concept is clear, and the precision is high. For the framework program designed by the one-time loading method, only a small amount of modifications are required, and the influence of the construction process on the deformation and internal forces can be considered.
