Survey on Design Procedures in Numerical Simulations of End-plate Moment Connections

Abstract

This paper gives survey on up-to-date studies which deal with numerical simulations of bolted end-plate moment connections. The selection is performed with the aim to cover different design concepts which reflect the problem of joint behaviour in general. Main characteristics of joint design and corresponding analysis features are presented in tabular form intended to serve as guidance for appropriate modelling of bolted end-plate connections. Consequently, the procedure for conducting numerical simulation in proper mode is proposed by authors. An illustrative example-case study of analysis of a extended stiffened end-plate bolted beam-to-column joint is shown. The design case is modelled with two finite element software packages which have different approaches and levels of complexity. Finally, the analytical calculation of this joint is done according to Eurocode 3 with the aim of validation. The moment-rotation curve, as a basis in this field, is obtained for each model. The results from numerical simulations with both the approaches are in good correlation. Basic characteristics of two mentioned design approaches are also explained as an orientation for engineers and reserchers in this field.
