This report summarizes the results of our ground motion evaluation for the proposed FRMWRK Office building to be constructed at 430 NW 10th Avenue in Portland, Oregon. Our geotechnical report for the project was submitted on November 30, 2015 (GeoDesign, 2015). The site is shown relative to surrounding features on Figure 1...

This project is aimed at developing a resilient timber buildings for high-rise and mid-rise structures using innovative energy dissipators. To improve the seismic performance of the structure, resiliency has become an important factor. Resiliency of the CLT building, in this proposal, is ensured by using novel hybrid building and innovative energy dissipator connectors. This will be undertaken within resilience-based design framework to enable building owners make an informed decision on the potential emergencies and downtime, and mitigate it at the design level. Indeed, this design framework is a departure from the current collapse prevention performance limit objective that will make tall timber building attractive to builders and owners. Furthermore, the use of innovative energy dissipators and structural systems can push the building height beyond the 12-storey proposed in the 2020 NBC.
1. Select ground motions suitable for NBC 2015/2020
2. Performance-based design mid-rise building incorporating energy dissipator
3. Damped outrigger building
4. Coupled walls with distributed dampers
