This document describes a C program for pushover (P-Delta effect) analysis of structures using the force analogy method based on Timoshenko beam theory. The program analyzes plastic hinges using moment-rotation and shear-shear deformation relationships. It takes inputs from multiple CSV files, runs the analysis, and outputs results to CSV and HTML files including a base shear-displacement graph. The program was written by Salar Delavar Qashqai and published on March 23, 2021.
