Flexural strengthening of steel and steel–concrete composite beams with FRP laminates

2013
This chapter is concerned with the flexural strengthening of steel and steel–concrete composite beams using adhesively bonded fibre-reinforced polymer (FRP) laminates... The flexural strengthening of steel/composite beams has become a topic of substantial interest in recent years mainly due to the ageing stock of bridges that contain steel or steel ...

FRP-FLEXURAL STRENGTHENING OF STEEL BEAMS: A FINITE ELEMENT ANALYSIS STUDY

Proceedings of International Structural Engineering and Construction, 2019
Fiber reinforced polymer (FRP) strengthening has been widely used for concrete structures. However, limited studies have been conducted on its application to steel structures. The use of FRP materials to retrofit steel members is an effective replacement

Role of Bond in RC Beams Strengthened with Steel and FRP Plates

Journal of Structural Engineering, 2001
This paper looks at the problem of predicting the stiffness, load capacity, and failure modes of RC members strengthened in bending with bonded steel or carbon-fiber--reinforced plastic thin plates. A critical issue of this strengthening technique is that, when the plate debonds, the load capacity suddenly drops and the failure mode is typically ...

Analytical modelling of FRP strengthened steel beams

2008
In this paper an analytical procedure to predict flexural behaviour of FRP strengthened steel and steel-composed elements, based on the cross-section behaviour, taking into account non-linear behaviour of the materials with any configuration of FRP reinforcement is shown.

Steel beam strengthening with UHM CFRP strip panels

Engineering Structures, 2021
Abstract Strengthening of steel beams utilizing FRP material has numerous advantages over traditional methods, which include bolting or welding new steel plates to the existing structure. Compared to other FRP material, Carbon FRPs (CFRPs) have been preferred for strengthening steel due to their higher stiffness.

Strengthening of Single-Span Steel-Beam Bridges

Journal of the Structural Division, 1982
The use of post-tensioning to increase the strength of steel beams in beam and concrete-slab bridges is shown to be feasible. The purpose of the study is to determine a technique for increasing the capacity of the bridges to meet today's loadings. The results of testing a half-scale model of an existing bridge indicate that post-tensioning can be used ...

Debonding of Steel Plate‐Strengthened Concrete Beams

Journal of Structural Engineering, 1990
The behavior of damaged concrete beams strengthened by externally bonded steel plates is analytically investigated using linear elastic fracture mechanics and the finite element method. The study includes investigation of the failure by interface debonding of the steel plate and the adhesive layer due to interfacial shear stress which exists at the ...

Strengthening of Laterally Restrained Steel Beams Subjected to Flexural Loading Using Low-Modulus CFRP

Journal of performance of constructed facilities, 2019
Upgrading the flexural design strength of the structural member for increased live load without disrupting the functionality of the structure is an arduous task.

Experimental study on CFRP-strengthened steel beams

Composites Part B: Engineering, 2018
Abstract Recently, as a viable alternative to strengthening or repairing steel bridges with welded or bolted plates, bonded CFRP plates have been used. The main goal of the presented study is to compare the flexural behaviour of steel beams strengthened with the CFRP plates.

Adhesive bonding in steel beams strengthened with CFRP

Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2009
The strengthening of metallic beams with a bonded carbon-fibre-reinforced polymer (CFRP) plate has found many applications in bridge and building structures in recent years. The structural behaviour of the adhesive bonding in this technique is the most distinct element to be considered.
