RESEARCH ON TYPHOON DAMAGE TO ENVELOPES OF LIGHT-WEIGHT STEEL BUILDINGS
Typhoon causes considerable havoc resulting in lossof property, and considerable damage to light-weight steel buildings in the coastal regions of China. The light-weight steel buildings are particularly vulnerable to damage from high winds. A field survey was undertaken to investigate the pattern of failure when typhoon passed in Dalian, Fuzhou and Xiamen, which had revealed that the main structures of light-weight steel buildings were intact basically and the building envelopes suffered the most wind damages. In this paper, observed modes of building failure in the windstorms are presented, including breakage of roof, wall damage and breakage of openings. Thus a construction model of typhoon damage is presented, and several factors relating to wind-induced damage have been described. In order to improve the wind-resistant capability of the buildings, and to improve the performance of roof systems, some engineering improvements are put forward, and systematic design measures for envelopes must receive more attention. This paper aims to analyze wind damage to light-weight steel buildings, and present possible remedial measures aiming at curtailing these occurrences. The results could be used as guides for the wind-resistant design, reducing the vulnerability of the building envelopes to typhoon disasters, and mitigating the consequent economic losses of light-weight steel buildings.
