Old reinforced concrete (RC) structures often exhibit unsatisfactory performances in terms of both residual serviceability and seismic behavior.
This study aimed at investigating the flexural behavior and serviceability performance of concrete beams reinforced with different types of GFRP bars.
The behavior at the serviceability stage was significantly improved by the prestressed Fe-SMA bars.
The HSC series specimens showed similar static flexural behavior, but lower serviceability, to that of the integrated specimen.
For this reason, it is necessary to take into account the variability of soil properties which can significantly affect the bridge behavior regarding ultimate and serviceability limit states.
Also, this behavior indicated that the overall serviceability of the PSC curved girders can be guaranteed in the service state.
The objective of this research was to experimentally investigate serviceability limit state aspects related to flexural behavior of concrete beams internally prestressed with glass fiber-reinforced polymer (GFRP) bars.
Although both topologies behave similarly with respect to serviceability criteria, there is a significant difference in behavior during deployment.
During the past years, a number of research programs have been directed toward the establishment of serviceability criteria for the evaluation of the dynamic behavior of floor systems under the action of human activities.
The design of slender floor structures, with steel or composite cross sections, is often limited by the serviceability criteria such as deflection limits and vibration behavior, rather than the strength criteria.
