Effect of Prying Action Forces on Design Method of Rigid Bolted Connections with Circular End Plate

摘要

This paper presents an exact way for computation prying action forces in bolted rigid connections with circular end plate by studying the behavior of this type of connections. Besides, finite element models of bolted connections with circular end plate is made in various geometry. Prying action effect in these models is regarded and collapse mechanism of T connections is used to computation stiffness. Also, deformation and distribution of surface press which result from prying action phenomena is used. With using the result from parametric analyses of connections, an improved method is presented to computation prying action. Then, an improved method is proposed to design bolted rigid connections with circular end plate in regard with prying action effect. Accuracy assessment of proposed method, will display efficiency and favor accuracy in designing bolted connections with circular end plate.
