Description:
The Engineering and Industry Building (EIB) at UAA is a 4 story moment frame structure that was completed in 2016. The building is instrumented with 18 strong-motion sensors (accelerometers) that measure the building’s movement during seismic events. On 30 November 2019, the Anchorage bowl experienced a 7.0 Magnitude earthquake, which recorded peak ground accelerations of approximately 0.3g. The combination of the building type, significant ground accelerations, and sensor records provides an opportunity to compare the building’s actual performance with its design intent and the behavior that was predicted by the prescriptive (code-based) design. The real-world feedback from the seismic event will also allow the calibration of structural models and subsequent prediction of building performance during a future, larger event. The purpose of this project is to conduct a time-history structural analysis of the structural elements of the UAA Engineering and Industry Building using the strong-motion record from 30 November 2019. This analysis includes comparing the performance with the code-based design, identifying locations of yielding and predicting performance and areas of concern for a larger event. Using the lessons learned in the from the EIB analysis, a preliminary design for the EIB Phase 2 structure will be completed. This is a proposed 2 story structure adjacent to the current EIB structure that incorporates a bridge to the UAA Bookstore.
