In this paper the analysis method from Majid (1963) for steel pitched portal frames is progressed so that we can study the influence of shearing action on the overall elastic critical buckling load when members are of Fibre Reinforced Polymer (FRP) material. For solid members of FRP the ratio of the longitudinal Young’s modulus to the shear modulus of elasticity can be significantly higher than...

in reinforced concrete design, there are situations where transfer of shear across a specific plane needs to be considered. examples of such situation include corbels, bearing shoes, ledger beam bearing, and a host of connection between precast concrete elements. in this study, the shear transfer behavior of reinforced concrete is investigated experimentally by conducting test on 6 precracked p...

This paper illustrates an optimization procedure of concrete beam-column joints subjected to shear that are strengthened with fiber reinforced polymer (FRP). For this aim, five different values have been considered for length, width and thickness of the FRP sheets which created 125 different models to strengthen of concrete beam-column joints. However, by using response surface methodology (RSM...

Experimental and numerical investigations on the retrofitting of half-scale wall-like reinforced concrete (RC) columns were conducted. The axial compressive behavior control un-strengthened RC column (having a section aspect ratio four) was compared with strengthened columns. by employing external confinement through fiber-reinforced polymer (FRP) wraps and/or steel/FRP strips with/without modi...

Abstract Fibre Reinforced Polymers (FRPs) are extensively employed to strengthen existing structures because of their several advantages over other strengthening techniques. On the hand, premature debonding FRP reduces its effectiveness in steel structures. Anchoring composites is an effective solution delay or even prevent debonding. Very limited anchorage methods, however, have been introduce...

concrete shear walls are the most prevalent structural systems resisting lateral loads due to earthquakes in high-rise buildings. very large in-plane stiffness of shear walls provides an excellent drift control in the structure. however, structural damages and early code shortcomings threaten the efficiency of existing structural walls against earthquake. recently, fiber reinforced polymer (frp...

Four putative open reading frames (ORFs) were previously identified in the regions flanking the Streptococcus mutans GS-5 fructosyltransferase (FTF) gene. One of these, ORF 3, appeared to code for a low-molecular-mass protein containing amino acid sequences sharing homology with several Gram-positive bacterial DNA-binding proteins and it was suggested that the ORF 3 gene product might be an FTF...
