Local FRP reinforcement of existing timber beams

چکیده
Timber beams in historic buildings tend to display signs of mechanical degradation the form large bending deformations and reduced capacity, often caused by timber defects. This paper addresses assessment resistance small subjected static loads, before after they have been reinforced using Fibre Reinforced Polymer sheets (FRP). The retrofitting elements FRP is not a new technique several experimental research programmes demonstrated that it possible increase capacity wood FRPs. It well understood premature failure under loading are defects (e.g. splay or dead knots, shakes, etc.). presents an work where locally applied area were noted. structural response when flexural was studied series experiments. results from tests demonstrate partially restore defective with application reinforcement method proposed this paper.

FRP for Flexural Strengthening of Timber Bridge Beams
The majority of timber bridges in Canada requires flexural and/or shear strengthening to increase their load-carrying capacity in response to the demand to increase the allowable gross vehicle weight. This paper presents an innovative approach for the use of fibre reinforced polymers (FRP) to strengthen timber bridges. The advantages of this strengthening system are inevitable: fibre reinforced...
متن کاملProposed Design Procedure of Nsm Frp Reinforcement for Flexural and Shear Strengthening of Rc Beams
Near-surface mounted (NSM) fiber-reinforced polymer (FRP) reinforcement has been found to perform efficiently as a flexural/shear strengthening technology for reinforced concrete (RC) members, while offering some additional practical advantages with respect to the most widespread technique of externally bonded laminates. This paper presents a design procedure for flexural and shear strengthenin...
متن کاملDebonding Failures of Rc Beams Strengthened with Externally Bonded Frp Reinforcement: Behaviour and Modelling
Both the flexural and shear strengths of reinforced concrete (RC) beams can be substantially enhanced using externally bonded fibre reinforced polymer (FRP) composites. Failures of such FRP-strengthened RC beams often occur by debonding of the FRP plate from the RC beam in a number of forms. Despite numerous theoretical and experimental studies on debonding failures of FRP-strengthened RC beams...
متن کاملTwo-Parameter Kinematic Approach for Shear Strength of Deep Concrete Beams with Internal FRP Reinforcement
Tests of deep concrete beams with internal fiber-reinforced polymer (FRP) reinforcement have shown that such members can exhibit lower shear strength than members with conventional steel reinforcement. To model this effect, the current paper proposes an approach based on a two-parameter kinematic theory (2PKT) for conventional deep beams. The 2PKT is built on a kinematic model with two degrees ...
متن کاملFire resistance of FRP reinforced glulam beams
Thin laminates made of high-strength pultruded fiber reinforced polymers (FRP) are increasingly being used to reinforce glue-laminated timber (glulam) beams, creating a new composite glulam (FRP glulam) significantly stronger in bending than a conventional (unreinforced) glulam of equal size. Large timber members have long been recognized for maintaining structural integrity in fires and this p...
