Structure Force System and Form Combination of Long-Span Structure Building to Lightening Design

Abstract

The structure form lightening is an inevitable trend on development of long-span building structure dimension. At the same time, the development of structure mechanics, materials science and component processing technology progress also becomes the important boost of promotion to structure regulation-controlling ability. This article draw a conclusion that, under the specific condition, structure form's change in fact is a materialized presents of forces system combination-changing through the dual overall analysis on classification of structural unit's stress and nature classification's of structure materials, in meanwhile according to the tension members` equivalent replacement principle between rigidity and flexibility components. It may provide new enlightenment and the feasibility method for form innovation of long-span architecture design through this particular instrumentality of transformation rule.
