Seismic Design Issue of Corner Slab-Column Connection

Journal of Earthquake Engineering, 2013
Design criteria of slab-column connections in the ACI Building Code [2011] were mostly developed from experimental results of interior connections. When dealing with corner slab-column connections, supplementary documents published by ACI Committee 352 and Committee 421 provide better explanations than the ACI Building Code [2011] and become useful ...

Seismic Design Criteria for Slab-Column Connections

ACI Structural Journal, 2007
Two-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.

Cyclic Lateral Loading of Nonductile Slab-Column Connections

ACI Structural Journal, 2006
Flat 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 ...

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

Ductility of Reinforced Concrete Flat Slab‐Column Connections

Computer-Aided Civil and Infrastructure Engineering, 2005
Abstract:  The article presents experimental and analytical research on providing adequate ductility and rotational capacity to reinforced concrete slab‐column connections. Post peak‐load ductility of connections in reinforced concrete framed structures is essential for ensuring structural integrity and preventing local failure that may lead to ...

Lattice Shear Reinforcement for Enhancement of Slab-Column Connections

Journal of Structural Engineering, 2012
An 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.

Punching Shear Capacity of Interior SFRC Slab-Column Connections

Journal of Structural Engineering, 2012
AbstractThe paper deals with the punching shear behavior and the capacity of interior steel fiber-reinforced concrete (SFRC) slab-column connections. In the experimental study, the effect of the amount of fibers on the punching shear resistance and cracking behavior of slabs was investigated on a total of 12 small-scale flat slabs of varying dimensions.

Moment Transfer by Shear in Slab-Column Connections

ACI Structural Journal, 1996
A 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.

Design Considerations for Slab-Column Connections in Seismic Zones

ACI Structural Journal, 1994
The 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 ...
