Steel plate-concrete composite slab has been attracted attention due to many advantages such as high structural performance, work-ability and reducing construction period. The general composite slab has a bottom skin plate with some stiffeners to make stiffness large. A new composite slab takes into the membrane effect of bottom skin plate without any bending stiffeners for concrete casting. Static and fatigue tests and elasto-plastic finite element analysis were carried out to make clear the structural characteristics of the new composite slab.
