摘要轻钢房屋被广泛用于民宅和厂房等低矮建筑中。该类结构轻质，对风荷载较为敏感，在台风中破坏严重，造成了巨大的经济损失，因此对该结构进行风灾评估具有重要意义。首先，基于随机模拟技术提出了轻钢房屋整体结构风致易损性的分析框架，其中涉及风荷载随机化方法、主体结构和围护结构风致易脆性分析方法以及房屋整体结构风致易损性分析流程。其次，基于所提框架对一具体轻钢结构风致易损性进行了案例分析，结果表明：所提方法较好考虑了飞掷物和风压联合作用及其造成的内压变化效应，并可将主体结构和围护结构的风灾损失进行融合，获得结构整体易损性曲线。

Abstract：Light steel houses are widely used in low-rise buildings such as residential houses and factories. The structures are light in weight and thus sensitive to wind loads. It has been severely damaged in typhoons, which has caused a lot of economic losses, thus the wind disaster risk assessment of light steel structures is of great significance. Based on this, the wind-induced fragility and vulnerability of light steel buildings will be studied. Firstly, an analysis framework for the wind-induced vulnerability of the overall structure of light steel houses is proposed based on stochastic simulation technology, which involves the wind load randomization method, the wind-induced fragility analysis method of the main structure and the envelope structure, and the wind-induced vulnerability analysis procedure of the overall structure. Then, the proposed framework has been used to analyze the wind-induced vulnerability of a specific light steel structure, and the numerical analysis results demonstrate that the proposed method takes into account the combined effect of windborne debris and wind pressure, and the change of internal pressure. In addition, the method can integrate the wind-induced loss of the main structure and the envelope structure to obtain the overall vulnerability curve of the structure.
