Abstract

This paper presents the numerically achieved results for the fire resistance of several types of floor structures which are mostly used in our residential and rural buildings and in same time fulfil the energy efficient criteria, as: semi-prefabricated reinforced concrete slabs system FERT and STIRODOM (with infill of extruded polystyrene -XPS), timber-concrete composite floor structure and traditional timber floor structure. The solid RC slab was analysed only for comparison. Using the computer programs SAFIR, the effect of the intensity of the permanent and variable actions and the effect of the thermal isolation on the fire resistance of simply supported slabs were analyzed. The fire resistance was defined with respect to the criteria of usability of the structures in fire conditions, according to Eurocodes and the standards in force.
节能楼板结构的防火性能
本文介绍了我国住宅和农村建筑中常用的几种同时满足节能标准的楼盖结构的耐火性能的数值计算结果,如:半预制钢筋混凝土板体系FERT和STIRODOM(填充聚苯乙烯-XPS),木结构-混凝土复合楼盖结构和传统木结构楼盖结构。实心钢筋混凝土板的分析仅用于比较。利用计算机程序SAFIR,分析了永久作用强度和变作用强度以及隔热作用对简支板耐火性能的影响。根据欧洲规范和现行标准,根据火灾条件下结构的可用性标准来定义耐火性能。
