NUMERICAL ANALYSIS OF STEEL-REINFORCED CONCRETE COMPOSITE GIRDERS
Journal Title: Civil and Environmental Engineering Reports - Year 2005, Vol 1, Issue 1
Abstract
The article presents a numerical model of a typical composite girder which consists of a strip of a reinforced concrete slab resting on a steel beam. Compatibility of horizontal displacements is assumed in the slab-beam contact region. The structure is subjected to unidirectional bending. The cross-section is divided into layers, either steel or concrete, and then analysed by applying non-linear characteristics of materials. The problem is solved by employing the finite element method. For a nonlinear system of equations the modified Newton-Raphson method is used. Examples of verification and illustration are enclosed. The stages of the composite structures under increasing loads are analysed in details.

NUMERICAL MODELLING OF THE STRENGTHENING PROCESS OF STEEL-CONCRETE COMPOSITE BEAMS
This paper presents the numerical modelling of strengthening a steel-concrete composite beam. The main assumption is that the strengthening is not the effect of the state of a failure of a structure, but it resulted from...
