Analysis of Prying Force in Extended Endplate Bolted Connections/Guo Bing(1 Institute of Civil Engineering, Shandong Architectural University,Jinan 250014,China; 2 Tsinghua University,Beijing 100084,China)
Abstract:In order to analyze the prying force which commonly exists in extended endplate bolted connections, finite element method considering contact problem is adopted to study the magnitude and distributing rule of prying force on the endplate interface, and the main inflection factors of prying force. Design method and advice are presented in practice.
Keywords:prying force; endplate bolted connections; finite element method; contact
