Reliability Analysis of RC Slab-Column Joints under Punching Shear Load Using a Machine Learning-Based Surrogate Model

open access: yesBuildings, 2022
Reinforced concrete slab-column structures, despite their advantages such as architectural flexibility and easy construction, are susceptible to punching shear failure.

Investigation of punching shear behavior of flat slabs with different types and arrangements of shear reinforcement

open access: yesCase Studies in Construction Materials, 2022
Punching shear behavior is experimentally investigated through testing a total of thirteen reinforced concrete flat slabs. Four different types of punching shear reinforcement configurations are examined, namely, ordinary closed rectangular stirrups (ST ...

Comparison of punching shear requirements in BS 8110, EC2 and MC2010 [PDF]

open access: yes, 2015
This paper compares design provisions for punching shear at internal columns in the superseded British Standard BS 8110, Eurocode 2 (EC2) and fib Model Code 2010 (MC2010).

Determination of the Punching Cross-Section of Reinforced Concrete Flat Slabs [PDF]

open access: yes, 2016
In this paper, the punching shear resistance of slabs without punching shear reinforcement is investigated. We assumed that the punching shear resistance can be characterized by the shear resistance of the concrete compression zone, and that the load ...

Slabs strengthened for punching shear with post-installed steel and CFRP connectors

open access: yesRevista IBRACON de Estruturas e Materiais, 2019
Structural accidents due to punching shear failures have been reported in flat slab buildings. Design recommendations presented by codes can lead to entirely different punching shear resistance estimates for similar situations.

Experimental and numerical analysis of micromechanical damage in the punching process for High-Strength Low-Alloy steels [PDF]

open access: yes, 2014
Sequential sheet metal forming processes can result in the accumulation of work hardening and damage effects in the workpiece material. The mechanical strength of the final component depends on the “evolution” of these two characteristics in the ...

Numerical integration of an advanced Gurson model for shear loading: Application to the blanking process [PDF]

open access: yes, 2013
A new extension of the Gurson damage model has been proposed recently to predict ductile fracture under shear dominated loads. The aim of this work is to verify the ability of this approach to simulate, in an accurate way, the damage evolution in ...

Multi-Objective Optimization Design of FRP Reinforced Flat Slabs under Punching Shear by Using NGBoost-Based Surrogate Model

open access: yesBuildings, 2023
Multi-objective optimization problems (MOPs) in structural engineering arise as a significant challenge in achieving a balance between prediction accuracy and efficiency of the surrogate models, which are conventionally adopted as mechanics-driven models

Punching shear analysis of slab-column connections [PDF]

open access: yes, 2013
The paper aims to present an experimental testing program regarding reinforced concrete slabs, with and without shear reinforcement, submitted to punching under both symmetric and eccentric loading.

Experimental characterization and numerical modeling of micromechanical damage under different stress states [PDF]

open access: yes, 2013
The use of HSLA steels for the manufacture of automotive components is interesting from an engineering point of view. This family of steels, while possessing high strength, also has good formability and can be used in forming manufacturing processes.
