一、高层建筑计算方法概述高层建筑的计算特点是:1.空间受力,而不是平面受力;2.框架一剪力墙结构或是剪力墙结构,而不是杆系结构;3.水平力在计算中起着决定作用。由于上述特点,人们在解决高层建筑计算时,习惯采用介乎平面一空间之间的空间协同法,此方法对垂直荷载仍是平面分析,仅考虑水平力下的协同作用。它就象手风琴一样收拢起来,进行总水平力的空间协同分析,然后又象手风琴一样张开把总水平力分配于每一榀抗侧力结构,最后是平面问题求解出所有杆件的内力。
1. Overview of High-Rise Buildings Calculation Methods High-rise buildings are characterized by the following characteristics: 1. Space stress rather than plane stress; 2. Frame-shear wall structure or shear wall structure, not bar structure; 3. Horizontal Force plays a decisive role in calculations. Because of the above characteristics, when people are solving high-rise building calculations, they are accustomed to using a space-based synergy method between the plane and the space. This method still analyzes the vertical load on the plane, and only considers the synergy effect of horizontal forces. It gathers like an accordion and performs spatial coordination analysis of the total horizontal force. Then it spreads like a accordion and distributes the total horizontal force to each lateral force structure. Finally, the plane problem solves the internal forces of all the rods.
