PBL剪力连接件力学性能研究进展

摘要

介绍了PBL剪力连接件(PBL shear connectors)的各种常见形式及其国内外的主要应用实例；从连接件的试验方法、破坏形态、极限承载力的影响因素和计算公式以及疲劳性能几个方面系统阐述了近年来国内外PBL剪力连接件的试验研究进展,其中重点阐述了连接件的极限承载力研究现状；并介绍了国内研究的一些新型PBL剪力连接件；最后,对今后PBL剪力连接件的进一步研究工作提出了建议.%The various common forms of PBL shear connectors and its main application examples both at home and abroad are introduced. The advance in test research of PBL shear connectors both at home and abroad is described from the test method of connectors,the failure pattern,the influence of the ultimate bearing capacity and calculation formula and fatigue performance in recent years,with the emphasis on the ultimate bearing capacity of connectors. And the new PBL shear connectors at home are introduced. Finally,the suggestions for further investigation on PBL shear connectors are presented.
