杭州国际会议中心钢结构抗火性能评估与设计

杭州国际会议中心总建筑面积117350m2。建筑功能复杂,包含高大空间共享中庭、大空间会议厅、标准客房、以及娱乐空间,建筑结构选型独特。对于这种综合性功能建筑国内现有的规范方法难以满足结构抗火安全性与经济性要求。本文基于性能化对杭州国际会议中心主体结构的抗火安全性进行了评估,首先确定结构抗火性能目标,然后对结构构件在可能最不利火灾场景下的力学性能进行分析,最后根据结构的受火性能是否满足抗火性能目标来评估结构的抗火安全性及需要采取的防火保护措施。本文结果被业主和消防主管部门采纳,可供类似工程的结构抗火设计参考。

Evaluation and Design on Fire-Resistance of Steel Structures for Hangzhou International Conference Center

The total area of Hangzhou international conference center is 117350m2. There are large communal aera, large meeting rooms, guest rooms and entertainment hall in this building. Since the function of Hangzhou international conference center is complex ,the existing build code isn' t suitable for evaluating the structural fire safety of the building. In this paper the evalution of the structural fire safety of Hangzhou international conference center is based on fire-resistance performance of the structure. At first the target of structural fire-resistance is determined. Then the behavior of structural members are analyzed in the most severe fire scenery. Finally the evaluation of structural fire-resistance and design of fire insulation are based on meeting the requirement of structural fire-resistance. The conclusions of this paper are adopted by building owner and fire bureau and can be referenced by other similar projects.
