模拟巨型框架结构在不同施工过程中的内力与位移比较

分析竖向荷载对结构的作用效应，由于巨型框架结构建筑工期漫长，以及多种不同的施工顺序等特点，应该较普通框架建筑更多考虑施工过程的影响。本文根据目前高层建筑巨型框架施工中较多运用的三种施工顺序，提出了三种考虑施工过程影响的竖向荷载作用效应分析方法并编写了相应的程序，用三种方法对某12层巨型框架算例进行分析和比较，结果表明，三种不同的施工顺序中竖向荷载作用下的内力和变形有一定的区别，最后给出了高层建筑巨型框架结构分析的几点建议。

Forces and Deformations of Mega-Frame Buildings in Different Construction Processes

Because of the characteristics of long time period, various construction processes, and so on for the mega-frame building, more attention should be paid to the influence of the construction process. Based on three kinds of construction processes, which are often applied in the mega-frame of tall building, three analytical methods of the vertical load effects, which taken into account the construction process effects, are introduced, and the corresponding computational procedure is presented. A 12-storey example mega-fmme is calculated by the three methods, and the results are compared with each other. It is shown that each process has its own characteristics and the difference between them is obvious. Some propositions are given to the analysis of vertical load effects for the mega-frame of tall buildings in the end.
