厚型钢结构防火涂料在往复大变形下抗开裂性能测试

The Anti-cracking Performance Testing of Thick Fire Retardant Coating under Large Reciprocating Deformation

对涂有水泥基厚型钢结构防火涂料的钢结构构件进行了不同荷载水平的往复加载试验,考查了在往复大变形荷载作用下钢构件的防火涂料开裂和附着性能,评估了地震等罕遇荷载下的钢结构表面厚型防火涂层情况,为钢结构防火涂料的设计与使用提供了参考。

The steel structures coated with cement-based thick steel structure fire retardant coating performance under different load levels of reciprocating load were measured. The cracking and adhesion performance of fire retardant coating of steel members were tested under large reciprocating deformation load. Assessing the apparent condition of the coating after the load of the earthquake and so on, and providing a reference for the design and use of fire prevention coatings for steel structures.
