STRUCTURAL ANALYSIS AND DESIGN OF HOISTING INDUCED SELF-FORMING GFRP ELASTIC GRIDSHELL

Abstract

Abstract: The hoisting induced self-forming GFRP elastic gridshells, which consist of long-continuous GFRP circular tubes, are such structures whose shapes are formed as a result of elastic deformations due to gravity during the hoisting process. By referring to existing design codes and literatures, analysis and design of such gridshell are conducted. Finite element model is established, in which multi load cases are considered. The structural responses regarding construction stage, serviceability limit state, ultimate limit state as well as stability are checked according to code provisions. The results show that the displacements, stresses, bearing capacities, and stability coefficients of the structure satisfy the design requirements.

Key words: GFRP composite materials, elastic gridshell, hoisting induced self-forming, form-finding analysis, structural design
