Effects of Ground Motion Duration on the Seismic Performance of a Two-Storey Balloon-Type CLT Building

The effects of long duration ground motions on the seismic performance a newly constructed two-storey balloon-type cross-laminated timber (CLT) building located in Vancouver, Canada, was studied. A three-dimensional numerical model developed OpenSees. connection and shear wall models were validated with test data. Twenty-four pairs short records approximately same amplitude, frequency content, rate energy build-up used for nonlinear dynamic analyses. Fragility curves based results incremental analysis to assess building’s collapse capacity. At design intensity level, motion shown not be critical factor as difference inter-storey drift ratio between two sets negligible. However, due larger number inelastic cycles, increased median probability by 9% when compared motions. Further research is required evaluate taller platform-type CLT buildings.
