本文克服了以往在计算高层建筑结构内力与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,较好地摸拟了实际施工的进程,使计算结果能更好地符合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 及以上级别的微机上,解决大型高层建筑结构的内力与变形计算问题,为工程应用提供了一个有力的手段。今通过对实例进行考核,发现它所运行的时间仅比通常一次加载时的机时增加40～50%。
This paper overcomes the errors caused by considering only one overall loading when calculating the internal forces and deformations of high-rise building structures. This model adopts a calculation model in which the structure is formed layer by layer and loaded layer by layer, and the actual construction process is well simulated so that the calculation results can better conform to the actual distribution of internal forces. At the same time, in the programming process, the decomposition of total rigidity is properly handled to avoid many duplicate calculations, so that the calculations can be organically combined with the formation of the structure layer by layer and the overall loading of the structure once, thus improving the speed of the program. At the same time, it can greatly increase the scope of use of the program, making the program able to solve the internal force and deformation calculation problems of large-scale high-rise building structures on the IBM PC286 and above microcomputer, providing a powerful means for engineering applications. Now through the examination of the example, it is found that the time it runs is only 40 to 50% higher than the normal loading time.
