Mechanical Model and Analysis of FRP Woven Web Structures

The fiber-reinforced polymer (FRP) woven web structure (WWS) is an innovative large-span spatial structure composed of FRP strips. The FRP strips are crossed each other and woven to form a flexible web plane, and the web is stressed integrally in out-of-plane. The WWS is a tensegrity spatial structure system made of flexible members, which has four mechanical statues. The basic assumptions and the 3D fundamental mechanical model of the simple FRP WWS which has ring beams and central symmetry FRP strips are studied. The mechanical equations are drawn. Based on the equations, three load cases of FRP WWS including integrally pre-stressed in out-of-plane, full span load and half span load are analyzed in theoretical method. The fundamental mechanical model of FRP WWS is established that provides the theoretical approach for analyzing FRP WWS.
