Description

Miyamoto provided an ASCE 41-13 Tier 1 and Tier 2 assessment and conceptual performance-based seismic retrofit design for the City’s 16-story, 146,000-SF City Hall building that was originally constructed in the early 1960s. The Tier 1 and Tier 2 assessments exposed significant structural and non-structural deficiencies that might preclude the building from being functional following a significant earthquake. Reno’s City Hall houses many of the municipality’s services that must be up and running for the public after a natural disaster. Miyamoto’s proposed seismic retrofit concept provided fluid viscous dampers in the building to act as “shock absorbers” to protect the building’s structural system. This will allow it to perform at a level of immediate occupancy following an earthquake. In addition to the major structural deficiencies mitigated by the retrofit concept, Miyamoto proposed improvements to key non-structural elements to bring the building to current standards such as the seismic anchoring of mechanical, plumbing and electrical equipment seismic anchorage and bracing of suspended ceilings and other architectural features of the building. The assessments were completed in 2018.
