    摘要:

    中国是台风频发国家,在台风登陆前对城市各类结构可能发生的损伤程度进行快速预测,对于评价城市防灾减灾能力和灾后应急反应工作能够提供重要依据。针对中国东南沿海城市风灾易损结构之一的轻钢结构工业厂房进行了风灾损伤估计的研究。首先对结构风灾受损原因进行了详细的分析,根据结构破坏特点确定围护构件及连接部位的可靠性为分析重点。台风荷载模型的建立考虑了外风压、风致内压和风致碎片的共同作用。结合规范给出了构件承载力的计算方法,详述了损伤估计的整个流程,划分了厂房结构损伤等级并给出了详细的指标,最后利用0601号台风珍珠实测数据实现了对所建模型损伤估计与预测的全过程。

    Abstract:

    Wind hazard damage estimation was addressed for light steel industrial buildings which were the typical wind vulnerable structures in southeast coastal cities. With parametric analysis of wind damage and the structural failure features, the envelop elements and the connecting elements were determined as the pivots of the damage analysis. Upon the consideration of the coeffect of exterior wind pressure, windinduced internal pressure and windborne debris damage, a typhoon load model was proposed. And with the calculation method of the element resistance from the regulation, the procedure of the damage estimation was described and the damage classification of industrial buildings was specified with detailed indicators. Finally, the proposed method was approved with the actual data of typhoon CHANCHU (0601).
