摘要
利用ABAQUS对钢管混凝土约束型屈曲约束支撑的传热性能进行分析。分析结果表明:约束型屈曲约束支撑约束屈服段芯板温度分布均匀,且在混凝土包裹作用下,温度仅为套筒温度的25%。根据CECS 200∶2006《建筑钢结构防火技术规范》得出不同受火时间条件下屈曲约束支撑的承载力变化趋势。基于分析结果,给出了钢管约束型屈曲约束支撑防火涂料的建议喷涂范围。
The heat transfer performance of concrete-filled steel tube buckling-restrained-brace was analyzed by ABAQUS.The results showed that the temperature distribution of core plate was uniform.And the temperature of core plate was only 25 percents of that of the outer tube.The changes in load-bearing capacities of BRB under different fire durations were calculated according to Technical Code for Antifire of Building Steel Structure （ CECS 200∶2006 ） . Under the results of FEM analysis, the recommend spraying range of fire retardant coatings of BRB was presented.
