How do JointLOCK System connections resist shear forces at the joint?
The JointLOCK System provides a rigid mechanical reinforcement connection and a rebated concrete shear key to transfer shear forces at the construction joint. Horizontal shear force resistance; In tensile zones of the concrete section the reinforcement and JointLOCK connection transfer the shear force in tension. In compression zones the concrete carries the shear force in compression. Vertical shear force resistance; The JointLOCK system’s rebated shear key allows shear force transfer across the slab to wall construction joint. In typical depth slabs the concrete has the shear strength to carry the vertical shear forces in compression. In concrete beams with low span-depth ratios the beam is detailed with vertical shear reinforcement stirrups to assist the shear force resistance of the concrete section. Note: There is currently no ASTM test method or compliance requirement for testing the shear capacity of mechanical splicing devices.
