Fragility Assessment of Slab‐Column Connections
Earthquake Spectra, 2015The development of fragility relations is an important step in the application of performance‐based earthquake engineering. Data from 69 tests were collected and reviewed to develop fragility relations for new slab‐column frame construction.

Seismic behavior of slab-column connections
Canadian Journal of Civil Engineering, 2000Brittle punching failure of flat plates can occur as a result of transfer of shearing forces and unbalanced moments between slabs and columns. During an earthquake, the unbalanced moments transferred between slabs and columns can produce significant shear stresses that increase the likelihood of brittle failure. This brittle punching failure mode must

Enhancing Performance of Slab-Column Connections
Journal of Structural Engineering, 2008The influence of concentrated reinforcement in the immediate column region, the use of high-strength concrete slabs, as well as using puddled fiber-reinforced high-strength concrete in the slab in a region close to the column were investigated. The slab concrete strengths of the specimens were 30, 35, 40, 55, 65, and 90 MPa. The performance of the slab-

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.

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

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.

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.

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 ...

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.
