Experimental Study of Corner Slab-Column Connection
ACI Structural Journal, 2014Punching shear design criteria of corner slab-column connections in ACI 318-11 are controversial. This paper presents some of the relevant issues using design examples. Two approximately full-scaled corner slab-column subassemblages were tested under combined gravity load and lateral displacement reversals. Each specimen consists of a 120 × 120 × 8 in.

Rehabilitation of reinforced concrete slabcolumn connections
Canadian Journal of Civil Engineering, 2002The paper presents work on punching shear rehabilitation and strengthening of existing slabcolumn connections. Four full-scale specimens representing slabcolumn edge connections were built and tested to failure. Three slabs were then repaired and strengthened and tested again.

Progress in Structural Engineering and Materials, 2000
Flat slabs are common structural elements for apartments, office and institutional buildings. Their weak point is the resistance against punching in the vicinity of the supporting columns. In this article the experimental evidence and the parameters that influence the shear resistance of two-way slabs are presented first.

Shear–moment interaction of slab–column connections
Canadian Journal of Civil Engineering, 1988The factors that influence the shear–moment interaction of slab–column connections are examined. The Canadian design code, CAN3-A23.3-M84, is evaluated on the basis of its agreement with the observed connection behavior. Other approaches to modelling slab–column connections are examined.

Strength Evaluation of Interior Slab-Column Connections
ACI Structural Journal, 2008This paper examines the effectiveness of using code design equations to evaluate gravity load capacity and lateral resistance of slab-column connections. The authors collected test data for interior flat-plate slab-column connections subjected to concentric gravity load and combined gravity and lateral loads. The connection strength was evaluated using

Seismic Rehabilitation of Slab-Column Connections
ACI Structural Journal, 2010The primary focus of the study reported in this paper is seismic rehabilitation of slab-column connections damaged under the application of lateral displacement excursions. Seven 2/3-scale interior slab-column connections were tested to quantify the effects of earthquake damage and the effectiveness of various rehabilitation techniques on repairing ...

Moment Transfer at Interior Slab-Column Connections
ACI Structural Journal, 2003The strength of slab-column connections is assessed, under the U.S. design standard ACI 318, using an interaction equation that includes contributions from both shear and unbalanced moment. Based on a reexamination of tests reported by Hanson and Hanson, the unbalanced moment at interior connections is shown to contribute far less to transverse shear ...

Punching resistance of slab‐column connections with openings
Structural Concrete, 2019AbstractThe paper deals with the punching resistance of flat slabs with openings adjacent to a column. The results of an experimental campaign carried out at a laboratory of the Slovak University of Technology in Bratislava (STU) are presented in the paper.

Slab-column edge connections subjected to high moments
Canadian Journal of Civil Engineering, 1998This paper presents test results of eight large-scale reinforced concrete flat plate edge connections. The test specimens consisted of two identical series. Each series consisted of four specimens, two with openings, in the vicinity of the column, and the other two without openings.

An Experimental Study of Slab-Column Connections
ACI Structural Journal, 1992Four slab-column subassemblages, modeled after a typical reinforced flat plate building, are tested under combined gravity and lateral loads. The testing program incorporates two levels of gravity loads and compares the effects of biaxial versus uniaxial lateral loading on connection behavior. To study the effectiveness of connection repair, one of the
