PINBOARD SUMMARY

Reinforced concrete (RC) structures such as parking garages and bridges are subjected to harsh environmental conditions which result in corrosion of the reinforcing steel bars. In the last two decades, fiber reinforced polymer (FRP) reinforcement has been used instead of steel bars to eliminate the deterioration of RC structures due to corrosion. One of the most common RC structural elements are continous beams, which are slender beams supported on more than two supports, i.e., comprising two or more spans. Continuous beams usually encounter different load intensities on adjacent spans. In this research, an experimental investigation was carried out to study the behavior of two-equal span continuous beams reinforced with glass FRP longitudinal reinforcement tested under different loading patterns. The test parameters include loading arrangement on adjacent spans, longitudinal reinforcement configuration, and design criteria. One reference beam was tested under symmetrical loads, while three beams were subjected to unequal loading on the adjacent spans. The widths of cracks and the deflections at mid-spans were evaluated. The test results showed that the span subjected to higher load experienced less crack width and deflection compared to the less load span. Also, the beam that was designed to satisfy serviceability criteria showed small percentage of moment redistribution due to the limited rotation capability of the adjacent critical sections.
