摘要
针对地震、恐怖袭击等突发性事件引起的次生火灾对大型建筑的破坏特点,比较了大型建筑与普通建筑在结构抗火性能上的差异;利用轴向非均匀温度应力模型,对大型建筑构件的抗火性能与结构抗火计算进行了分析,疏理归纳出了部分性能特征;提出了一套用于这类火灾特点的构件抗火计算理论方法。
Abstract: For the characteristics of unexpected events as earthquake and terror assault that may cause secondary fire to large-scale building, the difference of fireproof capability of large scale structures and general buildings is compared. By use of axial inhomogeneous temperature strain model, the fireproof function and structure fire-resistance of large structures are calculated and analyzed. Some characteristics of fireproof performance are summed up. A set of theoretical methods for calculating fire resistance of structures are presented.
