Displacement-Based Design of Hybrid RC–Timber Structure: Seismic Risk Assessment
Publication: Journal of Structural Engineering
Volume 145, Issue 11
Abstract
A cross-laminated timber (CLT) wall is a composite structural assembly with high strength and stiffness properties. In this study, the beneficial properties of this wall were used in designing a new CLT-reinforced concrete (RC) hybrid system building. The hybrid system consisted of an RC moment-resisting frame with CLT infill. The energy dissipation capacity of this system was further enhanced by using steel slit dampers as connectors between the CLT and RC beam. To facilitate the adoption of new technology in earthquake engineering applications, direct displacement-based design was used. The utility of the proposed system was illustrated on a six-story CLT-RC frame dual system. Performance of the proposed design method was shown by conducting nonlinear time history analyses with consideration of seismicity of Vancouver, Canada. The results indicated that the proposed CLT-RC hybrid system is capable of withstanding lateral forces due to intense seismic excitations.
