The purpose of this study is to evaluate the flexural performance of void deck plate inserted omega shaped steel plate (for reducing concrete) and TSC beam. In Composite Beam, install Shear Connectors in order to resist horizontal shear on an interface between two members. And when applying to the void deck plate slab, It can secure the structure that is not only reducing the weight of the building but also eco-friendly. Therefore this study is evaluated the flexural performance by monotonic loading test using actuators. The main parameters are a shape of shear connectors, concrete thickness of upper slabs, and width of haunch. The result of the test, TSC beam applied omega shaped void deck plate has any decline in flexural performance by reduction of concrete slab.
