| Research Abstract |
According to previous studies and experiments on cyclic behavior of steel beam with slab and composite effect, I conducted two; one is push-out tests of stud-bolt in various strain-rate, and the other is consideration of stress condition at the maximum bending strength. In push-out tests, the maximum shear strength in a stud-bolt increased as strain-rate became large. Moreover, under high-speed loading, crack did not appear on concrete and stud-bolt is easy to fracture.However, it is not clear the relationship between increasing of strength and dynamic loading not only the behavior of stud-bolt under high-speed loading. I considered stress transfer and applied condition in experimental formula on the maximum bending strength under static loading. From the consideration, it is clear importance of plastic neutral position, the effective width and bearing strength in slab.
