带转换层框剪结构施工顺序对结构受力影响的计算研究

Analysis of the Effect of the Construction Process on a Frame-Shear Wall Structure with Transition Layer

结构重力荷载是随着建筑结构的施工逐步施加的,现今常用的结构分析方法往往是按投入使用后的结构整体模型进行计算,而没有考虑实际的施工情况。此文所使用的结构重力荷载作用下施工模拟计算程序是在PK-PM系列软件的基础上编制而成的,考虑了结构刚度和结构重力荷载随着施工进程逐渐形成的全过程。通过对实际工程的计算分析,比较了不同计算模型下内力计算结果的差别,提出了对结构整体模型计算结果的修正方法。

Dead load is applied gradually with the construction of a structure. The common analysis method of internal force is based on the whole building, regardless of the actual construction process. The calculation program used in this pa- per is based on the PKPM series software, considering the structural rigidity and dead load are gradually formed with the construction process. The results of different models are compared with those in an actual project. The paper proposes the correction method on the calculation result of the whole model.
