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 ...

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.

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

Strengthening of Reinforced Concrete Slab-Column Connections with Carbon Fiber Reinforced Polymer Laminates

open access: yesApplied Sciences, 2019
This study presents the structural behavior and punching shear strength of the concrete slab-column connections strengthened with carbon fiber reinforced polymer (CFRP) laminates. The variables considered for the twelve specimens included the compressive

Resisting punching shear stress in reinforced concrete slabs

open access: yesMATEC Web of Conferences, 2018
Punching shear failure is a major problem encountered in the design of reinforced concrete flat slabs. The utilization of shear reinforcement via shear studs or other means has become a choice for improving the punching shear capacity.

Punching shear resistance of UHPFRC [PDF]

open access: yesIABSE Reports, 2019
<p>Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) is a high performance cementitious material with enhanced strength in tension and compression and significantly high energy absorption in the post crack region. Its mix composition is not much dissimilar from that of normal strength concrete.

Finite element implementation of punching shear behaviors in shear-reinforced flat slabs

open access: yesAin Shams Engineering Journal, 2015
Punching shear reinforcement systems such as studs and stirrups are used to improve the punching shear strength of flat slabs. A three dimensional finite element model (FEM) is developed through Ansys 10 computer software, to carry out the nonlinear ...
