Energy-Based Seismic Design Method for Coupled CLT Shear Walls
Ductile cross-laminated timber (CLT) shear walls can be achieved by vertically joining a series of CLT panels with ductile connectors. When such multi-panel systems have a well-defined center of rotation, the resulting kinematic behavior is termed as coupled-panel (CP). In this paper, an iterative energy-based design (EBD) method is proposed for CLT shear walls based on energy balance established on their CP kinematic. Holz-Stahl-Komposit (HSK) connectors were utilized for both hold-downs and vertical joints. The seismic energy demands were estimated from constant ductility hysteretic energy spectra established for elastic-perfectly-plastic single-degree-of-freedom oscillators. The lateral force-deformation characteristics were derived considering the CP behavior in elastic and plastic ranges. Subsequently, the ductility demand was evaluated from these force-deformation relations. The story-wise hysteric seismic energy demands were balanced by the cyclic energy supply. While the lateral yield resistances were attributed to the hold-downs and vertical joints, the lateral plastic deformations were attributed to the vertical joints. The proposed EBD method accounts for the preferred failure mode together with performance criteria derived from either target deformation limit-states or local deformation capacities of the energy dissipative components.
