在工程设计中，对框架结构的内力计算，常规分析方法是将自重荷载一次施加到框架构件上，但实际的施工顺序是逐层进行的，构件的自重荷载应是逐层施加上的．本文考虑框架结构的实际施工顺序，对不同参数的框架进行了土与上部结构之间的相互作用分析．结果表明，本文方法与常规方法所得出的内力值存在着很大的差异，尤以梁端弯矩为更甚．本文方法对于合理地进行多高层框架结构的内力分析具有一定的参考价值．
In the engineering design, the internal force calculation of the frame structure, the conventional analysis method is to apply the self-weight load to the frame member once, but the actual construction sequence is carried out layer by layer, and the self-weight load of the component should be applied layer by layer. This paper considers the actual construction sequence of the frame structure and analyzes the interaction between the soil and the superstructure with different parameters. The results show that there are great differences in the internal force values obtained by this method and conventional methods, especially the beam end bending moments. This method has certain reference value for the reasonable analysis of internal forces of multi-level high-rise frame structures.
