Key Points in Design of the Sheet Space Structure System

Abstract

In this paper the key problems related to the structural theory of the sheet space system are discussed. The principles for selection of the structure form and the mechanical analysis are described briefly. For the purpose of simplifying the design of this system the main functions of the professional software is narrated at the end and some related diagrams showing the influence of imperfection of structure on stability are also attached to the paper.

The Imperfection Sensitivity of Sheet Space Structure Based on the Contact Interactive

“…As a common kind of structure for important buildings, the imperfection of the structure is inevitable which is caused by installation deviation, initial bending, initial eccentricity, initial stress and other reasons. Therefore, the research of imperfection sensitivity is one of the important subjects of sheet space structures, meanwhile, the most important mechanical characteristics of the sheet space structure are the interaction between sheets and skeletons transmitting by the mutual contact force in their uncoordinated joint [3]. So it is necessary to take into account the contact interaction to reflect the actual work situation.…”
