【Abstract】 Based on general gap element models, the authors develop a refined elastic plastic gap element model used for analysis of contact problem in beam to column connections. After compared the results of this model with contact examples in lectures, the article gets a conclusion that the refined model is reasonable and reliable. It provides a useful method for studying the failed mechanism of beam to column joints with high strength bolts.更多还原
