Structural behaviour of recycled aggregate concrete filled steel tube columns strengthened by CFRP

This paper presents experimental research on structural behaviour of normal and recycled aggregate concrete filled steel tube (RACFT) columns externally strengthened with carbon fibre reinforced polymer (CFRP) sheets and subjected to axial loading. A total of 22 specimens were tested to investigate the influence of the following variables: (1) tube configurations, circular or square, solid or h...

Numerical Simulation of Debonding Failure of Reinforced Concrete Beams Strengthened with Externally Bonded Frp

As the life age of the existing structures are required to meet the changing demands on civil infrastructures. So strengthening and retrofitting are required. Recently many techniques to strengthen the reinforced concrete beams in flexural by using fiber reinforced polymer (FRP) had appeared. The most famous technique among them is strengthening the (RC) beams with externally bonded FRP sheet t...

Examining Concrete Cores by Non-destructive Techniques

Computed Tomography (CT) scanning has served as an important non-destructive research tool by providing twoand three-dimensional images particularly in medicine, biology and materials science. An example of its application in the area of materials is reported. Experimental study was carried out to investigate the effect of location within column element on the strength and porosity characterist...
