Utilizing fiber reinforced polymer (FRP) anchors can enhance the strength and delay the debonding of flexural FRP in strengthened reinforced concrete (RC) beams. In this study, two different techniques are used for applying carbon FRP (CFRP) spike an

An experimental program was developed in which dry carbon and glass fiber wires bundles were spirally wrapped around five longitudinal steel bars with 8 mm diameter to act as a passive confinement inside the concrete stub columns. Stub columns were m

In this paper, a generalized semi-analytical approach for lateral-torsional buckling of simply supported anisotropic, thin-walled, rectangular cross-section beams under concentrated load at mid-span/mid-height was developed using the classical lamina

The prediction of the actual ultimate capacity of confined concrete columns requires partial confinement utilization under eccentric loading. This is attributed to the reduction in compression zone compared to columns under pure axial compression. Mo

Recently developed high strength aluminum alloys (AA) have desirable characteristics that make them attractive as externally bonded strengthening materials. This paper investigates the potential of using AA plates for shear strengthening of reinforce

The objective of this experimental study is to assess the effect of new flexural anchorage devices on improving the performance of strengthened reinforced concrete beams in flexure. Six reinforced concrete (RC) beams were prepared and tested, three o

The use of carbon fiber reinforced polymer (CFRP) anchors has been shown to improve the performance of reinforced concrete (RC) beams strengthened in flexure with CFRP sheets. This improvement results from delaying or controlling the debonding of FRP

Recently, the need to increase the strength of reinforced concrete members has become a subject that civil engineers are interested in tackling. Of the many proposed solutions, fiber-reinforced polymer (FRP) materials have attracted attention due to
