Steel shell plate and steel frame, s3rc building structure

Abstract

A tri-layer steel reinforced concrete (S3RC) building structure comprises a steel frame, at least one steel shell layer, multiple rebars, and a concrete. The steel shell layer is mounted on the steel frame. The rebars are connected to the steel frame and located at one side of the steel shell layer. The concrete is mounted at the side of the steel shell layer and embeds the rebars. With the steel shell layer and/or the steel frame cover the concrete and the rebars, a tensile resistance of the concrete may be enhanced from the exterior, increasing the earthquake resistance. If the earthquake occurs and the concrete is shattered, the broken pieces may be covered by the steel shell layer rather than fall apart, avoiding collapse of the overall structure. Besides, the steel shell layer can also protect the concrete from being affected by the atmosphere and moisture, preventing the concrete from bulging and weathering.
