Slab shear connectors
WebThe repair involves welding headed-shear connectors on the intact portion of the web, bypassing the corroded region. Next, the area is encased in UHPC to create an alternate load path. The load is transferred from the shear connectors to the UHPC and down to the pier. Proof-of-concept experiments led by Dr. Arash E. Zaghi began in 2013. WebJan 27, 2024 · Each specimen consists of two precast concrete slabs, two B-S connectors and an H-steel beam. A 20 mm thick steel plate was welded to the top of the H-steel beam to distribute the load from the hydraulic jack. Each precast concrete slab has a shear pocket (120 × 140 mm) for the B-S connector.

WebPunching shear is the most common failure mechanism of slabs that are supported directly on columns. The slab–column connection is always vulnerable to critical punching shear; thus, it is necessary to investigate the effect of various parameters on the punching shear behavior of the flat slabs. This work presents an experimental study to evaluate the … WebStud shear connectors should penetrate at least two inches into the concrete deck (6.10.10.1.4). If fillets exceed 6 in., it is IDOT policy to reinforce the fillets to develop the shear studs. See Bridge Manual Section 3.3.9 for further guidance.
