Abstract

A 3D printed hollow bridge column structure is proposed with a concrete shell sandwiched between FRP and steel tubes. The microstructure and texture of the FRP tubes will be controlled by the 3D printing technique to enhance the interfacial bonding with concrete. Both modeling and experiments will be conducted to achieve the optimum multilayer design for enhanced structural performance under seismic loadings.
