Composite action can be achieved by providing shear connectors between steel top flange and concrete topping Composite sections have larger stiffness than the summation of the individual stiffness of slab and beam, therefore, can
carry larger load or similar loads with appreciably smaller deflection and are less prone to transient vibration. T-type Steel Composite beam(TSC-beam) is developed and tested. The test results of TSC beam are compared with the
theoretical results based on composite actions.

Common deck plates have longitudinal reinforcement located at a right angle to steel beam stretcher, install shear connector after setting up vertical bar on beam flange. Because of this characteristic, If shear connector have function of vertical bar, Construction will be improved. In this study, we did push-out experiment to compare three of new-shapes shear connector(rebar continued) to shear capacity of stud connector used by established shear connector.

Composite action is generally achieved hy providing shear connectiomi between steel top Flange and concrete topping. Composite sections have greater stiffness than the summation 0f the individual stiffness of slab and beam. Therefore. they can carry larger loads or similar loads with appreciably smaller deflection and are less prone to transient vibration. T-type Steel Composite beam (TSC-beam) was developed to increase these advantages. Ten specimens were tested for this study. During the experiment, crack pattern and deflection of beam were investigated. The examined results of TSC beam system were compared with results from the typical composite beam and RC beam.

In order to use in the middle or small size buildings, the Bottle Neck TSC beam is developed and it is to reduce the thickness of plate and the depth of beam. Test parameters are pitch of shear connector, arrangement of deformed bars in the slab, plate thickness of Bottle Neck TSC beam and quantity of tensile deformed bar. The purpose of this study is to evaluate flexural behaviour and ductility of Bottle Neck TSC beam(TSC Ⅲ). All specimen’s load-displacement curves are stable and composite actions of slabs and steel beam estimate bond strength of bolts, deformed bars and steel beam in slab. Deformability of Bottle Neck TSC beams are showed compare with an increase plate thickness and depth of beam.

Composite Beams have various effects as one unit structural member of a steel beam and a Reinforced Concrete Slab. In Composite Beam, install Shear Connectors to resist horizontal shear on an interface between two members. And when applying to the Deck Plate Slab, vertical Bars are installed for insure safety during the construction. Therefore, this study attempts to examine the ways to develop and utilize a New-Shaped Shear connectors which is functioning as vertical bars and also securing a higher shear capacity using Deformed Bar and Plate instead of Used-Stud Connector.
