Abstract

We have developed a new hybrid structure using CLT infill shear walls and a steel frame, for middle-rise and high-rise buildings. This structural system enhances the structural potential of CLT panels by holding them in the steel frame. A steel frame can support sustained load of a high-rise building without CLT shear walls and allows use of long-span beams. Based on these features, this paper firstly presents the relationship of the strengths of CLT shear walls, joints and beams, and then studies the seismic and fire resistance design of the new hybrid structure system, introducing an example project.
