摘要： 为了推广外伸端板连接节点的应用,在塑性铰分布及等效T形件理论基础上,采用理论方法对简化的四螺栓和八螺栓连接的等效T型件进行推导分析,得到一系列简化设计公式,并通过算例拟合简化设计公式系数.经由多个算例比较表明,简化设计方法计算结果与美国LRFD以及中国JGJ82规范取得良好的一致性,且简化设计方法计算便捷,便于工程应用.该项研究成果可为外伸端板连接节点工程推广应用提供参考.

Abstract: In order to popularize the application of extended end-plate connections, this research work, based on the theory of plastic hinge distribution and the theory of equivalent T-shaped parts, employs a theoretical method to deduce and analyze equivalent T-shaped parts connected by four bolts and eight bolts. Consequently, a series of simplified design formulas are obtained, and coefficients associated with the simplified design formulas are fitted in terms of calculated examples. The comparison of the calculated examples has demonstrated that all results calculated in terms of the simplified design method are in good agreement with the American LRFD CODE and Chinese JGJ82 CODE, and furthermore the proposed simplified design method is convenient for engineering predictions and applications. The research results may provide references for popularization and applications of the extended end-plate connections.

Key words: extended end plate connection, design method, plastic hinge distribution, equivalent T-stub, end plate thickness
