This OpenSees coding package is designed specifically for cyclic (hysteresis) modeling of reinforced concrete (RC) frames. This package delivers accurate, reliable simulations of RC frame behavior under cyclic loading, essential for seismic assessment, retrofitting, and research.

Features:

OpenSees-Powered: Built on OpenSees, the gold standard for nonlinear structural analysis, this package leverages material nonlinearity and advanced hysteresis rules for accuracy;

Precision & Validation: The code has been benchmarked against experimental data, ensuring realistic predictions of strength degradation, stiffness loss, and hysteretic energy dissipation;

Easy to Use: our ready-to-run scripts allow you to focus on analysis and interpretation rather than debugging.

Includes detailed documentation for deployment.

Ideal for:

• Seismic performance evaluation of existing RC buildings;
• Academic research & teaching in structural and earthquake engineering;

Key option:

✔ Advanced Material Models

✔ Accurate Hysteresis Simulation

✔ Flexible Modeling Options
