Abstract:
It has been generally accepted that for multi-level precast concrete construction, suspended floor systems can be supported by load bearing solid precast concrete walls. The typical connection between the floor and wall elements requires a supporting concrete corbel, or fire rated steel shelf angle connection, or for the precast floor system to bear directly on top of the precast walling system to provide the necessary bearing capacity for the floor. However, other efficient support connections are available for consideration, such as a Shear Friction Connection. The paper shall review the development of shear friction theory, examine an alternate shear friction precast floor-to-wall connection.
