Distribution of Bending Moments on the Plates of Carrier with Trapezoidal Cross Section

Abstract

This paper presents analysis of carrying capacity of the elements of cross-section (plates) with trapezoidal shape in carriers of box type. According to the model of linear character, some exact equations are formed. These equations are used for determination of moments that are transferred by flanges and webs of box carrier of trapezoidal cross-section. The criteria for application of the simplified expressions depending on the slenderness of the plate and the required accuracy of calculation are defined. This identification enabled the exact definition of plane compressive forces in order to analyze the buckling of plate carriers. Application of the results of this paper is a contribution to the process of optimal design of supporting structures, especially those that are used for construction of transport equipment, where the effect of reducing the weight affects on the efficiency of transport in supply chains.
