Shear strengthening of beam-column joints

Engineering Structures, 2002
Shear failure of beam-column joints is identified as the principal cause of collapse of many moment-resisting frame buildings during recent earthquakes. Effective and economical rehabilitation techniques for the upgrade of the joint shear-resistance capacity in existing structures are needed.

Shear Strengthening with Textile Reinforced Concrete

IABSE Reports, 2014
<p> A large part of existing bridges in Germany exhibits deficits in the shear capacity under static and cyclic loading according to the current design rules. More structures are expected to demand refurbishment and strengthening within the next years especially due to the current conditions of many older road bridges.

Shear strengthening effectiveness with CFF strips

Engineering Structures, 2003
Abstract The present work deals with shear performance of reinforced concrete (RC) beams with rectangular section. The RC beams are designed with shear deficiencies and strengthened by externally bonded carbon fibre fabrics. Four different configurations of externally bonded carbon fibre fabric strips are used to strengthen the reinforced concrete ...

Shear Strengthening—A State-of-the-Art Review

2018
Concrete structures, exposed to aggressive environment, are susceptible to chemical attacks such as carbonation and chloride contamination and destroy the alkaline barrier of cement matrix. This gives rise to spalling of concrete, degradation of steel and several other phenomena.

STRENGTHENING OF SHEAR AND MOMENTS IN CONTINUOUS BEAMS

Journal of Al-Azhar University Engineering Sector, 2020
Existing structures are subjected to increasing loads. They were often designed using Allowable Stress Design method (ASD). In old industrial buildings, beam dimensions were selected compact by using either rolled steel sections, or built up profiles.

Technique for Shear Strengthening—An Experimental Approach

2018
This chapter presents the experimental procedure for shear strengthening of RC T-beams strengthened in shear with GFRP sheet. The job is performed primarily in two stages. The first stage consists of selection and testing of relevant materials for the preparation of test specimens in the laboratory to establish the physical and mechanical properties of

Numerical Approach to Shear Strengthening of Beams

2018
Finite element method (FEM) is used to study the behaviour of RC T-beams strengthened in shear with GFRP sheet under two-point loading condition. The finite element analysis is carried out in this study using ANSYS finite element software. Specimens without GFRP as control beams, designated as S0-0L, S300-0L and S200-0L and beams strengthened with GFRP

Theoretical Approach to Shear Strengthening of Beams

2018
The shear strength of RC T-beams with and without GFRP obtained from experimental investigation is compared to the shear strength computed by the guidelines given in different standards such as American Concrete Institute (ACI 318-02), Canadian Standard Association (CSA A23.3-94) and Indian Standard (IS: 456-2000) building codes (without the provision ...

Shear strengthening of old concrete beams

Batiment International, Building Research and Practice, 1986
In our March‐April issue last year, the author described work at the Czech Technical University in Prague on the use of epoxy resins to apply new flat reinforcement to old concrete beams in order to enhance or prolong their service life. Here, some further test results and general conclusions are presented on the application of this technique to shear ...

Strengthening of shear wall with high performance RC jacket

2008
A new technique for the strengthening of existing R/C shear walls based on the application of thin high performance jackets is presented in this paper. The strengthening jacket is made of high performance concrete, having a compression resistance higher than 150 MPa, and reinforced by means of an high strength steel mesh.
