中文摘要：

轻钢房屋凭借其质量轻、工业化程度高和施工速度快等特点而广泛应用于低矮工业建筑中，但由于其对风荷载比较敏感，在强风条件下常常发生轻钢房屋的风致损坏事故并导致巨额经济损失．本文通过对灾后的调研，分析了轻钢房屋在强风条件下的风致破坏模式，用数值模拟分析了轻钢房屋的风致破坏特点，探讨了轻钢房屋风致破坏的机理，从工程施工角度分析了轻钢房屋的风致破坏原因并提出了相应的风灾防御建议．

英文摘要：

With characteristics like light weight, high industrialization degree and rapid construction speed, the light steel buildings have been widely used in low rise industrial buildings. However, these structures are vulnerable to strong winds. Severe damage to light steel buildings occurred due to strong wind, which could cause huge economic losses. Firstly, based on investigation of wind-induced damage, this paper analyzed the wind-induced damage modes of light steel buildings. Then, by using numerical simulation method, this paper illustrated the failure characteristics of light steel buildings and investigated the wind-induced damage mechanism. Finally, this paper discussed the construction causes of wind damage and provided recommendations for disaster reduction of light steel buildings. The information gained from this study will be useful to wind damage assessment and hazard mitigation of light steel buildings.
