Slenderness study of composite slabs modeled by explicit dynamic procedure

Composite slabs are popular flooring systems in steel-framed buildings. They have a lot of advantages which make their use the most feasible option in many situations. Slenderness ratio (shear span/effective depth) has a dominant effect on composite slabs. It is not possible to test the whole range...
