| Abstract: | This article disusses how the degree of shear connection affects static behaviors such as the slip between concrete slab and steel beam flange? the sectional stiffness? the deflection and the ultimate capacity of prestressed steel-concrete composite continuous beam. The stud connectors are adopted in the experiment and three steel-concrete continuous composite beams with deferent degrees of shear connection are designed. The beams are loaded in the middle of every span in order to study the static behaviors up to failure of continuous prestressed composite beams. |
