Typhoon resistance analysis of a single-story factory building with concrete bent-steel roof truss system

Abstract

The concrete structure workshop has strong lateral stiffness and can resist the general wind load; however, under extreme typhoon, the main structure may still produce large deformation. In this paper, based on the code for a load on building structures (GB50009-2012), the basic wind pressures on the surface of a single-story factory building with concrete bent and steel roof truss along the coast of Guangdong province are calculated, and the whole displacement response and local deformation of the main structure of the workshop under different typhoons are analyzed. The results show that the typhoon action perpendicular to the longitudinal direction of the workshop will cause the large deformation of the main structure, bring certain influence on the use function of the workshop building, and may lead to local crack in the concrete column, but it does not threaten the safety of the main concrete structure. Under the action of a typhoon, the steel frame structure of the parapet wall will appear as a large deformation, which is easy to induce the destruction of the retaining structure.
