摘要
以自重为主的恒载是随着主体结构的施工逐渐施加的,而常用的简化结构分析方法通常是按投入使用后的整体模型进行计算,显然与实际施工情况并不吻合。所介绍的恒载作用下施工模拟计算程序是在PKPM系列软件的基础上编制而成的,程序考虑了结构刚度和恒载随着施工进程逐渐形成和施加以及施工中预留后浇带的实际情况。通过算例,比较了不同计算模型下内力计算结果的差别,说明了施工模拟计算的必要性和程序的实用性。
Dead load that is mainly composed of self-weight works gradually with the construction of the major structure of the building,however,common simplified structural analysis model does not match it because it is often based on the whole building.The simulated calculation program under dead load is based on the PKPM software.This program can take the actual case that dead load works gradually and post-cast belts is set during the construction into account.The results under different models are compared by the given example,from which we can know that the necessity of simulated calculation and practicability of this program are obvious.
