A Proposal and Static Cyclic-loading Test on New Type of Rigid Connection of Steel Girder and Reinforced Concrete Pier

Abstract

In this paper, authors propose a new type of hybrid frame bridge connection consiting of steel girder and reinforced concrete pier. Through static cyclic-loading test, useful experimental data is obtained as a new type of connection of steel superstructure and substructure. As a result, the stress transfer mechanism of the rigid-frame structure can be made clear and the seismic performance of this structure was also clarified. Because of doing away with expensive bearing, this new type of hybrid frame can be expected to construct the bridge with high seismic resistant capacity saving in total construction cost.
