# Seismic Analysis of a Three-Span Concrete Deck Girder Bridge using Ansys APDL

This repository contains the complete scripts to model, load, and analyze a three-span concrete deck girder bridge in Ansys Mechanical APDL. The project evaluates the structural response under seismic loading using two distinct methodologies.

📌 Features & Methodologies

• Parametric Structural Modeling: Full geometry generation of a three-span concrete deck girder bridge system including columns, and deck.
• Equivalent Static Force Method: Application of lateral seismic forces computed via equivalent static force method.
• Linear Dynamic Response Spectrum Analysis: Multi-mode dynamic analysis utilizing design response spectra to capture peak displacement, bending moments, and shear forces.

📊 Expected Output & Visuals

Will be uploaded later.
