Concrete-filled steel tubular (CFT) columns have become popular as structural members in high-rise buildings. Data on the structural characteristics of 159 high-rise CFT buildings designed from 1968 to 2013 was collected. The structural planning and seismic design value of existing high-rise CFT buildings was analyzed as a function of their design generation. The following observations were made. The strength of concrete used in structures increased over time. As a result, the number of stories and story height increased. In recent years, seismic isolation structures and seismic structures with energy dissipation devices have largely increased in number.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
