Article
A design approach for strengthening reinforced concrete beams with externally bonded fibre reinforced polymer (FRP) laminates is proposed. The use of staggered FRP laminate bonding to the tension face of the beam is suggested as an economical design. The FRP development length suggested in the guidelines is adopted. It is recommended that the FRP U...
Article
The interior joint shear strength of nonductile frames strengthened with reinforced concrete (RC) jackets, but with no new joint shear hoops and no dowel anchors installed into the new and old concrete interface, was investigated experimentally. Seven oneway interior beam-column joint subassemblages were tested under quasistatic cyclic loading to o...
Article
Practical applications for the use of fibre reinforced polymer (FRP) composite materials for the seismic strengthening of reinforced concrete beams that have been constructed with a substandard beam bar termination method were experimentally investigated in this study. Results suggest that the cut-off reinforced concrete beam design does not meet t...
Article
The target of the research in this paper is using truss analysis to predict the behavior of reinforced concrete moment-resisting frames, especially for the joints with poorly reinforcing details. The truss analysis is basically constructed by truss mechanism for a cracked RC frame. Parametric study for discussing concrete softened coefficients and...

A total of 353 test results of interior and exterior BCJs were compiled from previous studies to develop the proposed model (Shin & LaFave, 2004;Leon, 1990;Birss, 1978;Fujii & Morita, 1991;Goto & Joh, 1996;Lee et al., 2010;Li & Ngoc Tran, 2009;Meinheit, 1977;Noguchi & Kashiwazaki, 1988;Noguchi& Kurusu, 1988;Oka & Shiohara, 1992;Park & Milburn, 1983;Park et al., 1981;Pessiki et al., 1990;Shiohara et al., 2001;Shannag & Alhassan, 2005;Supaviriyakit & Pimanmas, 2008;Wan & Hsu, 2009;Lee et al., 2010;Tran and Li, 2020;Morita et al., 1999;Otani et al., 1986;Fan et al., 2014;Yang et al., 2018;Melo et al., 2015;Alaee et al., 2015;Alaee and Li, 2017;Lee et al., 2020;Pampanin et al., 2002;Shiohara & Kusuhara, 2010;Lu et al., 2012;Durrani & Wight, 1985;Hwang et al., 2015;Joh et al., 2000;Hakuto et al., 2000;Kitayama et al., 1992;Kazuhiro et al., 1991;Lam et al., 2020;Au et al., 2005;Hwang et al., 2014;Joh et al., 1991;Alameddine, 1990;Pantelides et al., 2002;Ehsani & Wight, 1985;Kaku & Asakusa, 1991;Lee et al., 1977;Megget, 1974;Parker & Bullman, 1997; Paulay Specimen ...
... Over the last few decades, wide range of experimental and analytical research studies have been conducted on the structural behaviour of RC beams externally retrofitted by FRP composites and the research studies mainly related to the bonding of FRP composites to the bottom/tension zone of the RC beams and the research parameters were the type of FRP, an increase in thickness and the width of FRP layers. [1][2][3][4][5][6][7][8][9][10] The research outcomes of studies performed by Saadatmanesh and Ehsani, 11 Ritchie et al., 12 Chajes et al., 13 and Swamy and Roberts 14 confirmed that the bond strength at the interface between FRP and concrete determines the effectiveness of the FRP-strengthened RC beams and it has been suggested that suitable anchorage method in FRP external strengthening, to avoid the debonding of FRP composites FRP strengthening. [6][7][8]13,15,16 Uomoto et al. 16 recognized that the peeling stress development at the end of FRP composite limits the strength capacity enhancement of the beam. ...
