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

An experimental program was conducted to evaluate the seismic performance of rigid frames strengthened with externally bonded CFRP fabric and near-surface mounted (NSM) CFRP bars. Three rigid frame specimens were subjected to cyclic loading. The thre

There are only few experimental studies available in literature that focus on the effect of distributed U-wraps as anchoring system to secure FRP-strengthened reinforced concrete (RC) beams. Thus, this paper is intended to present a rational design m

The premature debonding of Fiber Reinforced Polymer (FRP) sheets has been well studied and understood for normal weight concrete. This type of failure mode can be averted by keeping the maximum FRP strain below the debonding strain of FRP as specifie

The flexural resistance of reinforced concrete (RC) members such as beams and slabs can be enhanced by bonding fibre-reinforced polymer (FRP) composite plates to their tension face. The effectiveness of the strengthening can be compromised though by

This paper presents the results for three full-scale T beams and three full-scale rectangular beams that were tested while strengthened with CFRP sheets and anchored using two types of CFRP spike anchors. For each beam type, the first specimen was lo

The technology of using FRP composites to strengthen concrete members has proven its effectiveness over the years. Accordingly, design guides have been developed to aid engineers in applying this technology. ACI 440.2R-08 is one of the major design g

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

This research program is intended to verify the influence of using distributed external U-wrap CFRP anchorage to shift the failure mode from overall debonding to sectional flexural failure for concrete beams externally bonded with CFRP sheets. Premat
