Headed shear studs are an essential interfacial connection for precast steel–concrete structures to ensure composite action; hence, the accurate prediction of the shear capacity of headed studs is of pivotal significance. FERO Thermal Tie™ - Slotted Stud (Type II) Masonry Connector transfers lateral load from the tie through a plate, which transfers the load to the stud backing. 754 (c) (1) (i): “Shear connectors (such as headed steel studs, steel bars or steel lugs), reinforcing bars, deformed anchors or threaded studs shall not be attached to the top flanges of beams, joists or beam attachments so that they project vertically from or horizontally across the. co. However, the specific placement and layout of the shear studs provided in flat plates tends to vary. The failure surface of the fractured studs consists of a smooth surface and a rough surface, which are associated with fatigue and fracture caused by. ). 25. Studs are generally placed in rows, the spacing (and thus the number per unit length) being dependent on the design shear force between girder and slab. Headed stud is well-known shear connector, which is usually welded to the steel beam of the composite beams to connect the steel beam to the concrete slab to achieve the required composite action and limits the interface slip. Best used in steel wall assemblies where the demands of vertical movement between the veneer and the.
