Improving Bolted Simple Connections Design Method in Regard With Effect of Prying Action

This paper presents improving analyses and designs method of end plate bolted simple connections, which is an exact way for designing this type of connections with load and resistance factor design (LRFD) and allowed stress design (ASD) method. Besides, finite element models of end plate bolted simple connections in various geometry is made and compared with experimental results. Prying action effect in these models is regarded and failure models are 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, an improved method is presented to computation prying action. Then, an improved method is proposed to design bolted simple connections in regard with prying action effect. Accuracy assessment of proposed method, will display efficiency and favor accuracy in designing bolted connections.
