This book comprises experimental, analytical and numerical investigations of open sandwich slabs. The objective of the experimental work is to evaluate the performance and behavior of open sandwich slabs and also for determining the shear interaction property of shear stud for use in numerical analysis. The analytical study is conducted to simulate the punching failure of open sandwich slabs. The stud is modeled by two types of element, bond link element represents the shear transfer action, and truss element represents the axial force. The mode of failure and the sequence of cracking are...
