Self-Balanced Prestressed Latticed Shell Structure and it's Research Development

Abstract

Self-balanced prestressed shell structure assembled with elements is a new spatial system composed by prestressed cable and strut elements. The structure can achieve the latticed shell design that the large span without the center column by the rational use of high strength bars and prestressed technology. This paper illustrates the design idea, stress mechanism and structure characteristics of the self-balance prestressed latticed shell. The current research status of self-balanced prestressed shell structure assembled with elements on structure form, shaping method, static and dynamic performances are briefly described in the presented work; It is seen that the research on test of structure mechanical properties, molding technology and structure dynamic performance is an urgent work to be solved in the development of the self-balanced pre-stressed latticed shell structure theory.
