Determination of Internal Forces in End Plates of Simple End Plate Joints

Abstract

In the paper the authors propose computer simulation of simple end plate joints. A computer model has been elaborated using the Autodesk Robot Structural Analysis Professional 2010 software programme. Maps of internal forces and stresses on end plates of a joint have been analysed. The analysis of the maps enabled the authors to determine the course of variation of bending moments in any cross-section of the joint and to compare the obtained diagram with a diagram of moments cited in the literature (ŻOŁTOWSKI et al. 2000, BIEGUS 1997), which serves the purpose of determination of the minimum thickness of end plates needed due to the lever effect. The paper also determines the dependence between the loading force acting on the joint and the thickness of end plates on the assumption of maximum stresses damaging the steel of the end plates, as this is one of the criteria for dimensioning end plate joints. In addition, effort of joint bolts was determined in relation to a value of the loading force.
