在在周围的温度下面的火和二 SRCSC 被执行以后,静态地, 20 钢的推外面测试在形状钢的表面上与饰钉接头增强了具体的短柱(SRCSC ) ,以便学习失败模式,装载滑倒关系并且界面砍在火以后的 SRC 成员的转移。试验性的结果证明典型失败模式和在火以后的 SRCSC 的装载滑倒曲线几乎与在周围的温度下面的盒子一样。界面砍 SRCSC 的转移不仅随标本经历了的山峰温度的增加而且随山峰温度持续时间的增加指数地衰退。界面砍与在钢网安排的饰钉一起的标本的转移比那些高得多,饰钉安排在钢凸缘。SRCSC 的实验公式界面砍在火以后的转移被建议,并且计算结果通常与试验性的结果同意很好。
Statically push-out tests of 20 steel reinforced concrete short columns (SRCSC) with stud connectors on the surface of shape steel after fire and two SRCSC under ambient temperature were carried out, in order to study the failure mode, load-slip relationship and the interfacial shear transfer of SRC members after fire. Experimental results show that the typical failure modes and load-slip curves of SRCSC after fire are almost the same as the case under ambient temperature. The interfacial shear transfer of SRCSC declines exponentially not only with the increase of the peak temperature the specimen experienced but also with the increase of the peak temperature duration. The interfacial shear transfer of the specimens with studs arranged at the steel web is much higher than those with studs arranged at the steel flange. Empirical formulas of SRCSC interfacial shear transfer after fire are proposed, and the calculated results generally agree well with the experimental results.
