AN ADVANCED METHOD OF SHEAR TRANSMISSION FROM SLAB TO STEEL BEAM OF THE COMPOSITE BEAM SUBJECTED TO COMBINED NEGATIVE BENDING AND HIGH AXIAL TENSION

The performance of the steel-concrete composite beam reduces the capacity in the negative bending region due to the formation of the cracks. The high axial tension applied in the steel section leads excessive sip between components and trends to form cracks at early stage, which brings the importance in advance methods in the structural components of the composite beam. These cracks can be controlled by resisting tensile forces and avoiding longitudinal slipping. The application of waveform steel strips with shear connectors as one component of mechanical device may be tallied the requirement in taking sufficient shear and tensile forces on the negative bending region of the composite beam subjected to combined negative bending and axial tension, which had the hypothesis of this research study. This research was accommodated with validated three-dimensional Finite Element (FE) models of composite beam subjected to combined negative bending and axial tension to predict the behaviour in the application of waveform steel strips with shear connectors with various parameters of waveform thickness and height. The significant performance was predicted in the shear flow forces developed and it is discussed in this paper with caused failure scenarios in the material components.
