“…The authors explain this by the viscosity effects and invisible micro-cracking in the concrete, rather than slipping which was minimal at the observed location. Another study of composite action based on the neutral axis was performed by Park et al [11] on a Fiber Reinforced Plastic deck connected to a steel girder. The neutral axis was identified and the composite action evaluated.…”

Structural health monitoring (SHM) is the process of continuously or periodically measuring structural parameters over time and the transformation of the acquired data into information about the actual structural behavior. The main goal of SHM is to provide quantitative and actionable information to infrastructure managers on a system-wide level. However, to achieve this goal, damage sensitive universal parameters need to be researched, identified, and implemented into SHM processes and data analysis. The neutral axis location has been identified as a potential parameter for damage detection, performance evaluation, and condition assessment of beam-like structures. This paper is intended to serve as a reference for researchers who are interested in the state of the art in evaluation of the neutral axis location, facts about the neutral axis behavior, and challenges associated with using the neutral axis for SHM purposes. Studies of the neutral axis in laboratory settings, controlled on-site testing, and on real structures in on-site conditions are presented and discussed. The main difficulties in using the neutral axis location for SHM purposes that are identified in this paper are: (1) its sensitivity to environmental effects such as temperature, humidity, and loading positions, (2) its natural variation in healthy cross-sections, (3) quantification of its sensitivity to damage, i.e. its damage detection capabilities in terms of the damage size and its distance from sensors, and (4) correlation between the neutral axis location and the capacity, performance, and condition of the monitored structure. The proof of concept has been provided with numerical modeling, and in the laboratory, and to some extent through controlled testing; however, a general onsite validation still remains a major challenge.

“…The results of the fracture test and the structural analysis using the ABAQUS, a commercial finite element analysis program, can be shown in Table 3. In ABAQUS analysis, the bolt connection of FRP deck and steel girder was simply simulated using the coupling constraints for the FRP Deck bottom flange node and steel girder top flange node on the bolt connection positions as proposed by Park et al [7], and linear elastic ranges are considered as analysis boundary. And also the S4R element, which is known to be as good to FRP bridge deck modeling for analysis is considered in this analysis.…”

Fiber reinforced composite materials have the merits of light weight and durability for bridge deck and are estimated to be superior in economy to conventional deck materials considering the life-cycle cost of bridge. In this study, fatigue tests were conducted for the span lengths of 2.0 m and 2.5 m in order to investigate the change trend of fatigue characteristics of composite material deck according to the change in the span length. The result showed that the fatigue life rapidly reduces to about 25% when the span increases by 25%. However, considering that the fatigue performance safety margin was approximately 1.6 times more than the design axle load of the DB-24 design truck load in Korea, even at the span of 2.5 m, it is judged that the FRP decks being considered can be effectively used at a span length of 2.5 m.

“…Subsequently different types of connectors result in different level of interaction between the steel and FRP structural members, referred to as hybrid interaction. Park et al (2006) investigated the level of hybrid interaction that can be achieved with bolted connectors. Davalos et al (2012) also investigated the level of hybrid interaction but for shear connectors.…”

As many bridges are reaching the end of their service life, researchers are searching for new solutions to extend the lifespan of those bridges. Fibre reinforce polymers (FRP) could be possible a solution for bridges with deck problems. Lightweight FRP decks can be installed quickly via bolted connectors on steel substructure. In general, shear force in the connector is not taken into account during the design of FRP decks because slip behaviour and interaction with steel substructure is unknown. This research connects to research at TU Delft on non-slip shear connectors for FRP decks. Aim of this paper is to quantify shear forces in bolted connectors due to traffic and temperature loads. The direction of webs, fibres in panel facings and the expansion coefficient of resin has been investigated to determine the influence of the FRP deck on the shear force in the connectors. To investigate the results of traffic loading and temperature loading on real bridges, a database of bridges in the Netherlands has been used. Results from the analyses offer an indication of the influence of the laminates on the shear force in the connectors and show shear force ranges that can occur in existing bridges.
