摘要

Railway elevated bridges in urban areas are often constructed under spatial restrictions in a limited span of time. So, an improved work efficiency and rapid work progress are essential requirements. Moreover, railway structures are required to show a high seismic resistance. The hybrid railway elevated bridge is a type of structure which meets such requirements. The authors have already proposed a method of evaluating the performance of the column of concrete filled steel tube (CFT) and beam of steel/reinforced concrete beam, which compose the hybrid railway rigid frame elevated bridge. However, there has been almost no study on the joint with concrete filled steel tube column. This paper discusses a design method of a newly developed beam-to-column insert joint, with cruciform steel and reinforcing bars inserted into CFT, on the basis of experimental study on its load bearing capability.
