Research Progress on Steel-Concrete Composite Bridge Towers

With the development of the steel-concrete composite structure, it has been found the new application form: steel-concrete composite bridge tower. Compared with the traditional concrete filled steel tubular column, composite bridge tower has connectors between steel panels and core concrete. Therefore, the mechanical characteristics of the composite tower are somewhat different with that of the composite column with no connectors. Some researches have been done on the composite tower and relevant research progress is introduced in this paper, which including the researches on composite bridge towers with different cross section types and with different connector types between steel panels and concrete.
