Abstract Summary
Mass timber is a wood product category that includes various alternatives. One of them is a veneer-based product known as Mass Ply Panels (MPP), which was recently introduced and certified per ANSI-PRG 320. A full-scale three-story mass timber building structure, which is 12.2 m by 12.2 m in plan and 9.1 m tall, was constructed and tested at Oregon State Uni-versity to demonstrate the potential of MPP in building application. The building structure comprises MPP diaphragms and walls, and laminated veneer lumber (LVL) beams and col-umns. Two dynamic tests were performed to characterize the dynamic properties of the structure. First, an implosion of a stadium within 300 m of the building location was used as the main excitation source, during which bi-directional horizontal acceleration data were collected for approximately 10 seconds. Second, an ambient vibration test was conducted to collect horizontal acceleration data for one hour. In both tests, sixteen accelerometers were used to record the structure's response. Due to the nature of the tests, the modal features were extracted using an output-only method and compared with the estimates from a finite element model. Lessons learned can be used to inform future modeling efforts of a mass tim-ber building to be tested on the Experimental Facility at the University of California, San Diego's high-performance outdoor shake table (LHPOST) and future codes.
