General

What this skill does


# FEA Structural Engine Skill

## Purpose

The FEA Structural Engine Skill performs structural analysis using finite element methods, including linear and nonlinear analysis, dynamic analysis, and comprehensive load combination processing per applicable design codes.

## Capabilities

- Linear and nonlinear structural analysis
- Static and dynamic load analysis
- Modal analysis for seismic design
- Stress, strain, and deflection calculations
- Load combination processing per ASCE 7
- Support for beam, column, plate, and shell elements
- Response spectrum analysis
- P-delta effects analysis

## Usage Guidelines
