Seismic Performance of Composite Beams Using Uplift-Restricted and Slip-Permitted Perfobond Rib Shear Connectors
Steel–concrete composite beams offer significant advantages in long-span, heavy-load, and prefabricated construction; however, the concrete slabs are prone to tensile cracking under negative bending moments. To enhance cracking resistance, uplift-restricted and slip-permitted (URSP) perfobond rib (PBL) connectors were...
