Structural behavior of precast concrete composite one-and two-way sandwich panels with different lower layers and lightweight concrete core under Flexural load

In this paper, the structural behaviour of precast concrete sandwich panels (PCSP) under flexure is studied. Finite element analyses (FEA) were carried out to study the behavior of composite precast concrete sandwich panels (PCSP) in order to examine feasibility of their usage as slab elements in th...
