Post punching shear pattern and progressive collapse of flat slab building [PDF]
Revista IBRACON de Estruturas e Materiais, 2023 The possibility of the occurrence of a second punching shear failure and of a Progressive Collapse after a punching shear failure had occurred in one flat slab column connection is investigated in two building structures, using Eberick and SAP2000 ...

Punching Shear Strength of Reinforced Concrete Flat Plates with Openings
Journal of Engineering, 2023 Test results of six half-scale reinforced concrete flat plates connections with an opening in the vicinity of the column are reported. The test specimens represent a portion of a slab bounded by the lines of contraflexure around the column.

Shear Strength Model for Slab-Column Connections [PDF]
Journal of the Korea Concrete Institute, 2010 Dept. of Architecture, Seoul National University, Seoul 151-744, KoreaABSTRACT On the basis of the strain-based shear strength model developed in the previous study, a strength model was devel-oped to predict the direct punching shear capacity and unbalanced moment-carrying capacity of interior and exterior slab-columnconnections. Since the connections

Case Studies in Construction Materials, 2019 Retrofitting of slab-column connections has become a crucial concern as they are highly vulnerable to fail in punching shear failure. External strengthening is practically feasible rather than the post-installation of shear reinforcement in deteriorated ...

Damage and Failure of a Column-Supported RC Flat Slab Subjected to Impulsive Loading
Applied Sciences, 2023 RC flat slabs supported by an array of columns subjected to the action of impulsive pressure were investigated. The slabs were designed for static loads according to current standards. The dynamic responses of 4 × 4- and 8 × 8-column-supported slabs were

Influence of the Location of the Column on the Load Capacity of a Slab-Column Connection for the Inner Column after Punching [PDF]
, 2013 Normally in practice the situation of a slab-column structure is rarely analyzed after the occurrence of a local breakdown. According to the regulations quoted in CSA A23.3 an adequately calculated bottom reinforcement crossing above the column may be ...
