考虑施工进程的高层建筑结构计算程序

本文克服了以往在计算高层建筑结构内力怀变形时由于只考虑整体一次加载而造成的误差，今采用结构逐层形成、逐层加载的计算模式，较好地模拟耻实际施工的进程，使计算结果能更好地任命真实的内力分布情况，同时在编制程序中，对总刚的分解作了适当处理，以避免许多重复计算，使结构逐层形成和结构整体一次加载下的计算能有机结合起来，从而提高了程序的运行速度。同时又可大大提高程序的使用范围，使得程序能在ＩＢＭＰＣ２８６及以

IMPROVEMENT OF PROGRAMMING IDEA FOR STRUCTURAL COMPUTATION PROGRAM FOR TALL BUILDINGS BY CONSIDERING PRACTICAL CONSTRUCTION PROCESS

This paper suggests an improved programming idea for structural analyses of tall buildings by simulat-ing the practical constructional process.This is to consider the bearing loads on the structure of the buildingduring construction are applied floor by floor,not that all loads are applied simultaneously at one time as thetraditional methods used to do so.In this way,the calculated numerical results of the stresses and displace-ments agree far better with the actural stresses and displacements of the tall buildings.Meanwhile,in theprogramming,the decomposition of the general stiffness matrix can be properly treated to avoid much re-peated computations,and the run of the program,it is possible to solve large scale problems on IBM PC 286and higher level personal computers.The numerical example in the paper shows that the computational timeis only 40 to 50% more than by thd former methods.
