Performance of shear stud clusters for precast

Simplified full-depth precast concrete deck panel systems for

Oct 11, 2016 · The grout near the studs may crack, causing the combined shear, bending, and even tension in the studs, which has been shown to greatly reduce the rigidity and strength of the studs. The push-out tests of studs subjected to combined tension and shear, as well as stud cluster with haunch, are recommended to investigate the behavior of

Design of shear connectors for precast concrete decks in

Full-depth precast concrete deck systems have several advantages over traditional cast-in-place concrete decks. Higher concrete quality, accelerated construction, and reduced life-cycle cost are the main advantages. Full-depth precast concrete deck systems can be designed as composite or non-composite systems with the supporting girders. Composite systems are commonly used due to their

Experimental and numerical study on shear studs connecting

Shear studs are often used to connect steel girders and concrete deck to form a composite bridge system. The application of precast concrete deck to steel-concrete composite bridges can improve the strength of decks and reduce the shrinkage and creep effect on the long-term behavior of structures. How to ensure the connection between steel girders and concrete deck directly influences the
