摘　　要：复杂体型的大型屋面结构由于其自身特点而对风作用十分敏感,极易受到强风的破坏。本文通过对某体育馆屋面遭受风灾事故的调查分析,探索了屋面风致破坏机制并分析了事故原因,提出了若干大跨屋面防范和减轻台风灾害的合理抗风措施。Large-span roof systems are sensitive to wind action and frequently be damaged under strong winds,especially when their shapes are relatively complicated.In this paper,the wind-induced damage of roof system of a gym on a tornado was investigated and its damage mechanism was analyzed.From this investigation,it can be obtained that several factors result in this damage,including the interaction of wind and roof system,wind-resistance details and design codes and so on.Based on this field survey,some suggestions on prevention or mitigation of wind-induced damage are given on for large-span roof system.
