Parametric study on the rotation capacity of stiffened end-plate beam-to-column connection

Rotation capacity is one of the joint parameters needed to be taken into account of the real joint behaviour in a global analysis. It has a special influence on the plastic design of steel frames. The results of the parametric study of the stiffened bolted end-plate beam-to-column connection have been presented in the paper. The main investigated parameters are: thickness of end plate “t_p”, horizontal bolt spacing “w” and distance of the bolt to plate edge “c_g1”. The analysis was performed with the use of finite element method, based on the numerical experiment plan.
