Abstract

The problems of conventional lap-spliced connection are long splicing length, narrow internal space and difficulty in maintaining verticality. Therefore, an innovative connection was proposed by adopting tubes instead of vertical rebars. The innovative connection can not only solve the listed limitations, but also optimize the mechanical behavior and the construction efficiency. This paper numerically investigated the axial tensile performance of the innovative connection based on the previous tests. The force-transferring mechanism was revealed and the parametric study was conducted by changing concrete strength, plate thickness, eccentricity, number of studs, and location of shear connectors. The simulation results indicated that the steel plate in the tension zone yielded along the X-shaped tension band. The axial tension was transferred through the concrete compression struts generated under the combined action of concrete, tie bars and studs. The influence of concrete strength on the axial tensile performance was relatively small. The influence of number of studs, location of shear connectors, plate thickness, and eccentricity on the axial strength and stiffness was significant. Besides, current specifications were evaluated and detailed design recommendations were given.
