Abstract: The authors have developed an innovative composite system between steel and concrete members combining the headed stud shear connectors and epoxy resin mortar. This system is called Post Rigid System (hereinafter, abbreviated to PR System), where the system have the behaviors of non- and full composite action under construction and in service, respectively. By using the PR System in steel-concrete composite structures, therefore, the introduction of prestressing force only into the concrete member can be done effectively. To confirm the applicability of PR System, fundamental tests were carried out. The resin mortar consist of epoxy resin and silica sands. It is possible to control the hardening time of resin mortar subject to a constructional plan of structure.
To eliminate the composite action between steel and concrete, the shank of each stud is wrapped by the resin mortar-A and also the attaching surface of steel girder against the concrete member is plastered by resin mortar-B. The stud shear connector used in the PR System is named Post Rigid Stud (hereinafter, abbreviated to PR Stud). The concept of the PR System, various test results of resin mortar and PR Studs, also an application example for an actual bridge are presented and discussed in this paper.
