《高层结构精确计算法》一书,将无剪力分配法与电子技术结合起来用于高层结构的分析,取得了可喜成果。此法特点是将杆件的转角位移方程经过处理,使其只包含角位移未知数,而线位移未知数不出现。这样,在不对称的单跨 n 层刚架巾共有2n 个角位移未知数,利用无剪力分配法建立结构刚度矩阵仅为2n 阶方阵。对于对称的单跨 n 层刚架,则其结构刚度矩阵仅为 n 阶方阵。在互联剪力墙的设计中,连系横梁采用变刚域的修正横梁刚度后,其计算方法完全与单跨高层刚架一样。在电算发达的今天,设法减少电子计算机的容量显然是十分重要的研究课题之一,为
The book “Precise Calculation Method for High-rise Structures” combines the no shear distribution method with electronic technology for the analysis of high-level structures and has achieved gratifying results. The feature of this method is that the angular displacement equation of the rod is processed so that it only contains the unknown angular displacement, and the unknown line displacement does not appear. In this way, there are 2n angular displacement unknowns in the asymmetrical single-span n-layer rigid frame towel, and the structural stiffness matrix created by the shearless distribution method is only a 2n-order square matrix. For a symmetrical single span n-layer rigid frame, the structural stiffness matrix is only an n-order square matrix. In the design of the interconnected shear wall, the stiffness of the modified beam of the variable-rigid region is used for the connecting beam, and the calculation method is completely the same as that of the single-span high-rise rigid frame. Today, when computing is well-developed, trying to reduce the capacity of electronic computers is obviously one of the most important research topics.
