摘要
预应力效应是在施工过程中逐步建立的,而常用的结构分析方法一般按投入使用后的整体模型进行计算,显然该计算模型与实际施工情况不符。本文介绍的预应力混凝土结构施工模拟计算程序是在PKPM系列软件基础上编制的,该程序对常用的张拉方案具有良好的适用性。通过算例,说明了施工模拟计算的必要性以及该程序的实用性。
The effect of prestressing force develops gradually during the construction process, but the common structural analysis model does not match it because the structural analysis is carried out on the whole building. Based on the PKPM software, the simulated calculation program presented in this paper is applicable for the construction project that is commonly used. By the given example, it is demonstrated that the employment of the simulated calculation method is necessary and the program is practical.
