Behavior of biaxially restrained precast slabs in torsion

New findings from tests and numerical simulations

For several decades, precast slabs with cast-in-situ infills have been successfully used in building construction and, more recently, in civil engineering. These precast elements are usually produced in thicknesses ranging from 5 to 6 cm. The reinforcement running in the main direction is inserted at the precast plant. To ensure the intended biaxial load-bearing behavior, the secondary reinforcement is usually laid on top of the precast units. Another option is to insert the secondary reinforcement already at the factory. In this case, additional reinforcement needs to be installed along the...
