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

Usage Guidelines

When to Use

• Determining seismic design parameters
• Generating response spectra
• Classifying site conditions
• Establishing seismic design category

Prerequisites

• Site location coordinates
• Geotechnical data for site class
• Risk category identified
