Research on the Flexural Behavior of Profiled Steel Sheet–Hollow Concrete Composite Floor Slab

Buildings
In order to reduce the self-weight of steel sheet–concrete composite slabs and fully apply the superior performance of the composite slabs, this paper proposes a kind of open-profiled steel sheet–hollow concrete composite floor slab.

Experimental and Numerical Studies on the Mechanical Behavior of a Novel Bidirectional, Prestressed, Prefabricated, Composite Hollow-Core Slab

Buildings
Prestressed, precast composite panels are a type of building component that combines prestressing technology with composite materials; but, for most of them, it is difficult to balance structural stress performance and assembly efficiency.
