Experimental Study and Numerical Simulation on Mechanical Properties of the Bottom Plate in the Assembled Composite Slab with Additional Steel Trusses

Advances in Civil Engineering, Volume 2021, Issue 1, 2021., 2021
The composite slab with steel trusses is composed of precast bottom plate and cast‐in‐place concrete. In engineering applications, cracks often appear in the bottom plate before casting the upper concrete, which even leads to the failure of the composite slab.
