Punching shear resistance of reinforced concrete footings: evaluation of design codes

Revista IBRACON de Estruturas e Materiais, 2018
Punching is a possible failure mode for slender footings and it may lead a structure to ruin through progressive collapse. Although footing present different geometric characteristics, their punching shear design is based on the empirical methods used ...

Experimental Investigation of Punching Shear on FRP Strengthened Slab [PDF]

, 2018
Punching in slabs is generally seen by the application of concentrated loads or to the presence of columns. One of the major phenomenon related to flat slabs is its punching shear capacity at slab column connection.

LONG-TERM AND CORROSION EFFECTS ON THE PUNCHING SHEAR RESISTANCE OF RC FLAT SLABS SUBJECTED TO SUDDEN COLUMN LOSS

, 2023
During an extreme event occurring on a reinforced concrete structure, characterized by the loss of a load-bearing element, the remaining resisting members may develop alternate load paths to resist gravity loads. However, it is recognized that reinforced

Hybrid Machine Learning Algorithms for Prediction of Failure Modes and Punching Resistance in Slab-Column Connections with Shear Reinforcement

Buildings
This study presents a data-driven model for identifying failure modes (FMs) and predicting the corresponding punching shear resistance of slab-column connections with shear reinforcement. An experimental database that contains 328 test results is used to

Punching Shear Design Method of Voided Slabs

, 2017
This study presents punching shear design method of voided slab in accordance with arrangement of voids around columns. According to previous studies, the slab-column connection of voided slabs is weaker than that of the solid slab due to the lack of ...
