平面抗侧与空间协同结构计算视野下的上海80年代高层建筑研究

Planar Lateral Resistance and Spatial Synergy AStudy of 198Os Shanghai's High-rise Buildings in the Perspective of Structural Calculation

20世纪80年代上海先后建成的八百多栋各类高层建筑,大多采用中国自主研发的平面抗侧、空间协同、薄壁杆系三类计算程序,分别计算高层框架、框剪、筒体结构体系的内力和位移.文章通过项目图纸之研读,技术文献之查阅,现状之调研,指出对柱、剪力墙、薄壁杆件的平面抗侧和空间协同机制的认识,基于有限元方法编制的结构计算程序以及电算能力的进步,有效支撑了上海80年代高层建筑设计的探索:建筑高度由几十米发展到超百米,平面由简单到多元,空间由统一到变化,造型由规整到流动.

More than eight hundred various types of Shanghai's high-rise buildings built in 1980s mostly have adopted three types of calculation programs developed independently in China:planar lateral resistance,space synergy,and thin-walled rod system.These three types aimed to calculate the internal forces and displacements of high-rise frame,frame-shear,and tube structural systems respectively.Through the study of project drawings,literature review and field investigation,this article points out that the understanding of planar lateral resistance and spatial synergy mechanism of columns,shear walls and thin-walled bars,the structural calculation programming based on finite element method and the progress of electrical calculation ability have effectively supported the exploration of Shanghai's high-rise building design in 19805:the building height developed from tens of meters to over 100 meters,the plane developed from simple to diversifed,the space developed from unified to varied spaces,and the shapes developed from regular to flowing.
