Repair and Strengthening of Reinforced Concrete Slab-Column Connections
IABSE Congress, Chicago 2008: Creating and Renewing Urban Structures – Tall Buildings, Bridges and Infrastructure, 2008<p>Seven 2/3-scale interior slab-column connections were tested to quantify the effects of earthquake damage, and the efficiency of various rehabilitation techniques on repairing seismic damaged slab- column connections and improving the two-way shear strength of deficient connections. Three alternatives for rehabilitating slab-column connections

Lattice Shear Reinforcement for Enhancement of Slab-Column Connections
Journal of Structural Engineering, 2012An experimental study was performed to investigate the unbalanced moment-carrying capacity of slab-column connections reinforced with lattice shear reinforcement. Cyclic loading tests were performed on four specimens with this lattice shear reinforcement.

Seismic Design Criteria for Slab-Column Connections
ACI Structural Journal, 2007Two-way slabs without beams are popular floor systems because of their relatively simple formwork and the potential for shorter story heights. Earthquakes, however, have demonstrated that slab-column frames are vulnerable to brittle punching shear failures in the slab-column connection region and dropping of the slab, which are costly to repair.

Moment Transfer by Shear in Slab-Column Connections
ACI Structural Journal, 1996A bending moment M u transferred at a slab-column connection is resisted at the slab critical sections by flexure and shear. The ACI 318-89 Building Code 1 and the Canadian Standard CAN3-A23.3-M84 2 give an empirical equation for the fraction γ V of the moment M u to be transferred by shear at the slab critical section at d/2 from the column face.

Cyclic Lateral Loading of Nonductile Slab-Column Connections
ACI Structural Journal, 2006Flat slabs with discontinuous bottom reinforcement are susceptible to progressive collapse if punching shear failure occurs at a slab-column connection. Many such failures have occurred in past earthquakes, resulting in significant loss of life. The evaluation of older flat-slab buildings must include a realistic prediction of the response of the slab ...

Strength of Slab-Column Connections with Shear and Unbalanced Flexure
Journal of the Structural Division, 1976Tests were conducted on eight 1/2-scale models of reinforced concrete interior flat plate-column connections transferring shear and unbalanced moment from gravity and simulated seismic loading. The slab at the connection contained either no shear reinforcement or shear reinforcement in the form of either cranked bars, structural steel shearhead or ...

Design Considerations for Slab-Column Connections in Seismic Zones
ACI Structural Journal, 1994The transfer of shearing forces and moments between concrete flat slabs and columns can produce brittle punching failure. Slab-column connections must satisfy adequate strength against punching failure. In seismic zones, the connections are expected to undergo deformations into the inelastic range and, hence, it is necesary to design connections with ...
