摘要: 提出了一種適用于大跨度、大空間建筑的火災安全分析方法——性能化抗火設計方法.首先通過火災場景分析及模擬計算,確定構件的溫度,再利用分析軟件計算各不同溫度下構件的應力,確定需要防火保護的構件.青島北站主站房建筑結構體系復雜,超大空間的建筑布局,超出現有建筑防火設計的規定,現行規范方法難以滿足抗火安全性與經濟性要求.基于性能化方法對青島北站主站房的抗火安全性進行了評估,并根據評估結果確定防火保護措施.Abstract: A performance-based fire-resistant design method was proposed for analyzing the fire safety of a large span and large space building. First, the temperatures of components are determined through fire scene analysis and simulation, then the stresses of components at different temperatures are calculated by software, thus which component needs fire protection can be determined. The main station building in Qingdao North Station is a complicated structure system, a large space layout, and beyond the specifications of fire safety design codes. According to the current standards it is difficult to satisfy the safety and economic requirements. The performance-based method was used to evaluate the fire safety of the main station building in Qingdao North Station, and some fire protection measures were given on the basis of the evaluation results.
