Abstract
The invention relates to a steel-encased concrete-steel beam composite coupling beam and a construction method thereof and belongs to the technical field of building structures. The composite coupling beam consists of a steel beam section in the middle, steel-encased plate-concrete composite beam sections at the two ends and separating plates, wherein the steel beam section consists of flanges and a web; each of the steel-encased plate-concrete composite beam sections consists of steel webs, steel flanges, and in-fill concrete and shear connecting pieces; and the separating plates are positioned in the junctional zones of steel-encased plate-concrete composite beam sections and the steel beam sections and are in welded connection with steel plates of the corresponding steel-encased plate-concrete composite beam sections and steel beam sections. The composite coupling beam can be used for connecting a steel-encased plate-concrete composite shear wall or a reinforced concrete shear wall. Compared with a single steel-encased plate-concrete composite coupling beam, the steel-encased concrete-steel beam composite coupling beam can be prevented from breakage of beam-end plastic hinges due to relatively poor deformation capability, and is stronger in deformation and energy dissipation capabilities. Compared with a single steel coupling beam, the steel-encased concrete-steel beam composite coupling beam remarkably reduces the material consumption, is more flexible in design and has a wide application prospect.
