Abstract: A comparative analytical study of the average bond strength at failure of reinforcing bars embedded in unconfined normal-strength concrete (NSC) and high-strength concrete (HSC) is undertaken. The analysis makes use of an ...

Abstract: There is a renewed interest in using steel fiber reinforcement within the critical hinging regions of reinforced concrete (RC) members as a means for improving their seismic response. Examples include beam-column joints, ...

Abstract: A model for predicting the moment‐rotation relationship of partially prestressed concrete beam‐column joints under generalized excitations is presented. The model accounts for both the inelastic rotation in the beam inelastic ...

Abstract: The transfer of forces across the interface between steel bars and concrete through bond is one of the most important aspects that control the behavior of reinforced concrete members. This paper summarizes the results of ...

Abstract: This study concentrates on analytical evaluation of the effect of external confinement using fiber reinforced polymers (FRP) sheets on the response of concrete rectangular columns designed for gravity load only and having ...

Abstract: In 2003, an experimental research program was initiated at the American University of Beirut with the objectives of (1) evaluating the effectiveness of external fiber-reinforced polymer (FRP) confinement in improving the ...

Abstract: The development/splice strength and the pullout local bond stress-slip response of glass fiber-reinforced polymer (GFRP) bars in tension were experimentally investigated using beam specimens and pullout specimens, respectively. ...

Abstract: In 1998, AASHTO-LRFD adopted a new equation for evaluating the stress

Abstract: An experimentally based relationship of the cyclic local bond stress–slip response of steel bars corresponding to splitting mode of bond failure is developed. The relationship is composed of a monotonic envelope response ...

Abstract: This study concentrates on experimental evaluation of the effect of fiber reinforcement on the bond response of steel bars under load reversals. Beam specimens with symmetrical spliced top and bottom steel bars were used ...
