This Python code performs a pushover analysis of a truss subjected to lateral displacement (Material and Geometric Nonlinearities) using both custom calculations and the OpenSees library.
Key steps include:
1. Parameter Initialization: Sets geometry, material properties, and simulation parameters.
2. Custom Calculation: Uses Newton-Raphson iterations to calculate displacement and force responses for truss members based on incremental displacement.
3. OpenSees Modeling: Creates a finite element model, applies boundary conditions, loads, and performs displacement-controlled analysis.
4. Post-processing: Reads displacements and forces from results files.
5. Plotting Results: Compares Python and OpenSees results to validate the analysis.
