Nonlinear finite element analysis of steel-concrete composite slabs using explicit dynamics procedure

Composite slab construction using permanent cold-formed steel decking has become one of the most economical and industrialized forms of flooring systems in modern building structures. Structural performance of the composite slab is affected directly by the horizontal shear bond phenomenon at steel-c...
