ABSTRACT
The paper aims to investigate the bending behavior and free vibration of the concrete-steel composite floors, including high temperatures. The inspected properties are analyzed for the maximum displacement, load capacity, energy absorption capacity, and acceleration by using bending tests for varying stud density and elevated temperatures. Withal, bolts are used as studs throughout this study. The result of bending tests implies that, decreasing the spacing of the studs and the addition of mesh reinforcement and steel fiber will increase the energy absorption and maximum load capacity of the steel composite floors. Besides, the increasing the stud density reduces the vibration response of the composite floors, and the mesh reinforcement eliminates the efficiency of the steel fiber on the vibration response of the steel composite floors. Meanwhile, increasing the steel-fiber content causes the reduction in the vibration response of the slabs exposed to high temperatures.
