冷弯奥氏体不锈钢螺栓连接结构的抗火实验研究

摘要

Outline Research background High temperature test methods Steady state tests Test results and analysis Conclusions,The bolted connection design rules in currentinternational stainless steel design specifications aremainly based on those of carbon steel.Only applicable at room temperature condition;Currently, there is no design rule for stainless steelbolted connections at elevated temperatures.Therefore,over 400 tests and 450 numerical models forcold-formed stainless steel single shear and double shear bolted co nnections were carried out at elevated temperatures at The University of Hong Kong.
