STRUCTURAL MODEL ANALYSIS OF FRP WOVEN WEB STRUCTURES

FRP strips, which are light-weight, high-strength and anticorrosion, are crossed and woven to form a flexible plane FRP web. The web can acquire the adequate stiffness and bearing capacity in the results of the tension applied by tendons in out-plane direction. Then the tensed FRP web can act as roof structures. It is an innovative structure for the FRP application for large-span buildings. In this paper, the basic configuration of FRP woven web structure is introduced, and its structural characteristic is investigated. Three key states of a simple FRP woven web structure from the construction to the service, including the initial prestressed state, the out-of-plane tensioned state and the service loading state, are analyzed. The response of strips within a simple FRP woven web structure is finally examined, which confirms the feasibility of the structure form.
