摘 要:玻化微珠保温混凝土是适应我国建筑节能新形势提出的结构自保温材料。本文通过试验研究和理论分析,确定了玻化微珠保温混凝土的热工性能参数。运用ABAQUS有限元分析软件对玻化微珠混凝土梁在三面受火和四面受火条件下进行非线性分析,得出了其截面温度场的分布规律。
Abstract: Thermal insulation glazed hollow bead concrete is the insulation material of building, which can adapt the new situation of the building energy conservation in China. Through the experimental study and theoretical analysis, the thermal properties parameters of thermal insulation glazed hollow bead concrete are determined. The finite element analysis software ABAQUS is used to analyze the non-liner characteristics of glazed hollow bead concrete beams in the three-sides and four-sides fire conditions, and the characteristics of the section temperature field are obtained.
