FROM-FINDING METHOD AND CONSTRUCTION SIMULATION OF HOSTING INDUCED SELF-FORMING GFRP ELASTIC GRIDSHELL

Abstract

Abstract: Hoisting induced self-forming GFRP elastic gridshells are made of long-continuous standardized glass fiber reinforced polymer (GFRP) circular tubes with properties of high elastic strain and low modulus. The space surfaces of the gridshells, which mainly behave as the bending deformations of the tubular members, are automatically formed because of the gravity effects during hoisting. By employing finite element method and programming tools, this paper presents a form-finding algorithm for a certain type of elastic gridshell that has the single symmetry plane, followed by the numerical simulation of hosting construction process. The proposed form-finding algorithm is proved to have good calculation accuracy and efficiency to meet the design and construction requirements. The constructed GFRP gridshell structures are found to behave reliable load bearing capacities.

Key words: composite materials, GFRP elastic gridshell, hoisting induced shape forming, form-finding, constriction simulation
