Behavior of Reinforced Concrete Corbels

Structural Engineering and Mechanics, 2009
Test results of thirteen reinforced concrete corbels with shear span-to-depth ratio greater than unity are reported. The main variables studied were compressive strength of concrete, shear span-todepth ratio and parameter of vertical stirrups. The test results indicate that the shear strengths of corbels increase with an increase in compressive ...

FE Analysis of Reinforced Concrete Corbels With Enhanced Continuum Models

Finite Elements in Analysis and Design, 2011
The paper presents quasi-static FE-simulations of the behaviour of short reinforced concrete corbels with and without shear reinforcement. Concrete was modelled with the aid of three various constitutive continuum models: an isotropic elasto-plastic, an isotropic damage and an anisotropic smeared crack approach. To ensure the mesh-independent numerical

Analysis of Shear Model for Steel-Fiber-Reinforced High-Strength Concrete Corbels With Welded-Anchorage Longitudinal Reinforcement

Materials, 2023
According to the shear capacity test results of six steel-fiber-reinforced high-strength concrete (SFHSC) corbels with welded-anchorage longitudinal reinforcement under concentrated load, the effects of shear span ratio and steel fiber volume fraction on

The Behavior of Reinforced Concrete Corbels

PCI Journal, 1976
An experimental study is reported of the behavior of reinforced concrete corbels subjected to both vertical and horizontal loads. Twenty-eight corbel specimens were tested, of which twenty-six contained horizontal stirrup reinforcement. The variables included in the study were the shear span to effective depth ratio, the ratio of the vertical load to ...

Effective Strengthening of Reinforced Concrete Corbels Using Post-Tensioning

Engineering Structures
This paper focuses on a reinforced concrete corbel strengthening method using post-tensioning cables, or just using the prestressing strands themselves, which are led through additionally drilled cable ducts.

Shear strength of reinforced concrete corbels

Magazine of Concrete Research, 2009
In this study, 15 reinforced concrete corbels with shear span-to-depth ratio greater than unity were tested. Test results indicate that the shear strength of corbels increases with increase in compressive strength of concrete, parameter of main reinforcement and parameter of vertical stirrups. The shear strength of corbels also increases with decrease

Analysis of unsymmetrical reinforced concrete double corbels

AIP Conference Proceedings, 2020
Unsymmetrical reinforced concrete double corbels have different shear spans (a) in each side. ACI 318-14 provisions allow the structural analysis and design of double corbels through either shear friction (SF) method or the Strut-and-Tie modeling (STM). The current study presents analysis procedure using both SF and STM.

Behavior of Reinforced High‐Strength‐Concrete Corbels

Journal of Structural Engineering, 1994
Results of an experimental investigation on the behavior of corbels made with high‐strength concrete in excess of 40 MPa are presented. A total of 16 life‐size corbels were tested, two of which were unreinforced. The primary variables of the investigation were presence of horizontal force, reinforcement ratio, and shear‐span‐to‐depth (a/d) ratio ...

Design proposals for reinforced concrete corbels

PCI Journal, 1976
Simple design proposals for normal weight and lightweight reinforced concrete corbels are presented, based on previously reported experimental studies. A "Model Code Clause" embodying the design proposals is detailed, together with a step-by-step procedure for practical application.

Column‐Load Effect on Reinforced Concrete Corbels

Journal of Structural Engineering, 1990
The paper reports tests carried out on 18 150×150×200 mm concrete corbels reinforced with main bars and steel fibers. The fibers are used as a secondary (shear) reinforcement. The volumes of main and fibrous reinforcements and the shear span-to-depth ratio are varied. A concentric load is applied on the column segment of eight specimens.
