| Abstract: |
| Hybrid steel frame and timber shear wall structure was a green and low-carbon structural system suitable for multi-story buildings. Timber shear walls could be divided in two types： light wood-framed shear wall and mass timber shear wall. A basis could be provided for structural design by comprehending the influence of different shear wall types on the seismic response of structures. In this paper, a novel uniaxial hysteretic model developed for timber structures was used to simulate hybrid structures with two types of wood shear walls. Four-story building structure models with and without friction damper on the top of the walls were established. Nonlinear time-history analyses under frequent and rare earthquakes were conducted. As a result, the distribution of responses, including the inter-story drift, the force level of structural components, and the dissipated energy, were obtained. Lastly, the influence of shear wall types on these responses was revealed and generalized. |
