Design model for composite beam-to-reinforced concrete wall joints

Abstract

In this paper, a design model for composite beam to reinforced concrete wall joints is presented and discussed. The proposed model is an extension of the component method to this type of joints. The characterization of the active components is therefore performed in terms of force-deformation curves. In this type of joints, special attention is paid to the steel-concrete connection where "new" components, not covered in EN1993-1-8, are activated. The application of the model allows obtaining the joint properties in terms of moment-rotation curve. The accuracy of the proposed model is verified by comparison against available experimental and numerical results. The latter were developed in the FE program ABAQUS and previously validated against experimental results.
