Earthquake Analysis: Abaqus

1. Introduction Earthquake analysis is a critical component of structural and geotechnical engineering. Abaqus, a powerful finite element analysis (FEA) suite from Dassault Systèmes, offers robust capabilities for simulating structural behavior under seismic loading. Unlike simple equivalent static load methods, Abaqus allows for transient dynamic analysis that captures the time-dependent nature of ground motion, material nonlinearity, geometric nonlinearity, and contact effects.

This guide explores the methods, modeling techniques, and best practices for performing earthquake analysis in Abaqus/Standard (implicit) and Abaqus/Explicit (explicit). Abaqus supports several approaches, each with specific use cases: abaqus earthquake analysis
