INSTRUCTOR: Brian Kehoe, P.E., S.E. F.ASCE
Purpose and Background
To assess a building's seismic vulnerability, local jurisdictions or building owners may require an engineer to perform an assessment of the building to identify need for seismic strengthening. ASCE 41-17 provides a three-tier methodology for evaluation and retrofit of existing buildings. This is the latest update to the seismic evaluation procedures previously prescribed in ASCE 31-03. This webinar describes the Tier 1 seismic screening phase of the ASCE 41-17 standard on seismic evaluation of existing buildings. Also covered are the requirements for level of seismicity and the building's performance level. The standard defines a methodology that can be applied to buildings in all seismic zones, with varying requirements depending on the level of seismicity.
Primary Discussion Topics
- Determination of seismic hazard
- Characterization of buildings into common building types
- Updates in the ASCE 41-17 Tier 1 evaluation procedures
- Use of the Tier 1 checklists
Learning Outcomes
- Understand how to identify the seismic hazard and performance level for use with the Tier 1 seismic evaluation
- Be able to characterize buildings by one or more of the common building types
- Identify the steps required to determine whether a building can be classified as a benchmark building
- Select and complete the appropriate building and nonstructural checklists
