Abstract
Railway elevated bridges in urban areas are often constructed under many spatial restrictions in a limited time. Moreover, railway structures are demanded to show the high seismic resistance. A hybrid railway elevated bridge may be a structure to meet above-mentioned requirements. Authors have already proposed a method of evaluating performances for concrete-filled tubular steel pipes and concrete encased steels, which are used as column and beam members in hybrid railway rigid frame elevated bridges respectively. On the other hand, a design method of beam-to-column joint panels of hybrid railway elevated bridges is not enough clarified.
This paper describes a design method of a newly developed beam-to-column insert joint, where steel frame and rebars are inserted into concrete filled tubular steel columns, based on the experimental study.
