Seismic Hazard Analyzer Skill
Purpose
The Seismic Hazard Analyzer Skill performs seismic hazard analysis including site classification, spectral acceleration determination, and design response spectrum generation per ASCE 7 and AASHTO.
Capabilities
- Site classification determination (A-F)
- Spectral acceleration calculation (Ss, S1)
- Design response spectrum generation
- Seismic design category determination
- Site-specific hazard analysis
- USGS API integration for site data
- Risk-targeted ground motion parameters
- Site coefficient calculation
