摘　　要：在绿色低碳建设的发展理念下,装配式钢结构建筑技术大力发展。钢结构建筑连接节点构造复杂,金属连接件种类多,所形成的热损失量不易估算。论文基于有限元传热分析方法对钢结构预制混凝土墙板楼板连接节点进行了热工性能模拟计算,详细核算了由钢结构主体形成的结构性热桥以及由金属连接件形成的点热桥所造成的热损失。由于钢制连接件具有多维热传导属性,通过模拟计算结果可见,即使每个部件均采用了较好的断热桥措施,组装后形成的整体构造热损失仍是不可忽视。Under the development concept of green and low-carbon construction,the technology of assembled building with steel-structure is vigorous development.Because steel-structure buildingjoint structureis complex and metal connector category ismore,so theresulting heat lossis not easy to estimate.Based on the fi nite element heat transfer analysis method,the thermal performance of steel-structure precast concrete wallboard and floorjointsis simulated.Theheat loss caused by structural thermal bridgeformed by steel structure main body and point thermal bridge formed by metal connector is calculated in detail.Because steel connectors have multidimensional heat conduction properties,through the simulation results can be seen,even if each component has a good thermal bridge,theoverallstructural heat loss after assemblyis stillnotnegligible.
