In-situ Load Testing Results of Hybrid Composite Beam Bridges in Missouri, USA
Abstract
This project involves the Field Evaluation of three Hybrid-Composite Beam Bridges recently constructed in Missouri, USA. These hybrid composite beams (HCB)s are comprised of three main subcomponents that are a composite shell, compression reinforcement, and tension reinforcement. In the preferred embodiment, the shell is comprised of a fiber reinforced polymer (FRP) box beam. The compression reinforcement consists of self-consolidating concrete (SCC), which is pumped into a profiled conduit within the beam shell. The tension reinforcement consists of galvanized steel tendons anchored at the ends of the compression reinforcement. The main objective of this paper is to discuss the in-situ structural behavior of the bridge(s) through load testing. In order to accomplish this objective, beam elements were instrumented in one of the bridges with various sensors and instrumentation. This paper discusses the behavior of the HCB elements in-situ under load testing and presents comparative finite element modeling results.
