10-Story Stiffness-Graded RC Frame Analysis Engine How do you visually audit higher-mode effects and inelastic drift profiles in mid-rise structures? While standard code-compliant workflows rely heavily on simplified, linear elastic abstractions, performance-based validation requires a deep dive into nonlinear material behavior and transient structural dynamics. To bridge this gap, I developed an integrated Python simulation pipeline that couples OpenSeesPy for non-linear finite element evaluation with Matplotlib for publication-grade visualization and high-scale modal animation. The full open-source implementation script is documented and ready for deployment. https://lnkd.in/gAvVT-Pp #StructuralEngineering #EarthquakeEngineering #OpenSeesPy #PerformanceBasedDesign #FiniteElementAnalysis #CivilEngineering #Python programming #StructuralDynamics

Benchmarking Numerical Models with First Principles: OpenSeesPy 2-Story RC Frame Hysteretic Evaluation In advanced computational structural engineering, building a complex non-linear finite element model is only half the battle. The true validation of any numerical pipeline lies in its alignment with first-principles structural mechanics. I have put together an open-source OpenSeesPy pipeline designed to simulate the non-linear cyclic performance of a 2-story, 1-bay moment-resisting reinforced concrete frame. To test the robustness of the script under long-span configurations, I updated the layout to a 6.0m bay width featuring deep 400x600mm beams paired with 400x400mm columns. The complete open-source Python script and simulation engine documentation are now live. #StructuralEngineering #OpenSeesPy #SeismicDesign #FiniteElementAnalysis #CivilEngineering #EarthquakeEngineering #ComputationalMechanics #ReinforcedConcrete #NonlinearAnalysis https://lnkd.in/gZXrmNy6

OpenSeesPy Seismic Behavior Evaluation Dashboard for RC Columns In advanced structural engineering practice, validating nonlinear finite element analysis (FEA) against classical plastic mechanism theory is crucial for ensuring simulation integrity. To streamline this verification workflow, I developed an automated Python pipeline that couples OpenSeesPy with Matplotlib to execute a cyclic displacement-control analysis of a cantilever reinforced concrete (RC) column and render a clean, publication-quality evaluation dashboard. The source code and implementation documentation are available on https://github.com/Dr-Wahab/OpenSeesPy-Seismic-Behavior-Evaluation-Dashboard-for-RC-Columns.git . #StructuralEngineering #OpenSees #EarthquakeEngineering #ComputationalMechanics #FiniteElementAnalysis #StructuralAnalysis #PythonEngineering

Eid al-Adha Mubarak 🌙 Wishing you and your family peace, happiness, good health, and abundant blessings on this special occasion.

Happy to share a verification example for a plugin I developed for Steel02 in Abaqus. In this example, I compare the Abaqus response with an equivalent OpenSeesPy nonlinear pushover model to check consistency in force-displacement behavior, deformation shape, and overall structural response. It was a great exercise in model calibration, section definition, material matching, and understanding the small details that create gaps between different FE platforms. I’ve included a video showing the comparison and verification workflow. https://youtu.be/21-4yn3iVDI Would love to hear your thoughts from others working with Abaqus, OpenSees, and nonlinear steel modeling. #Abaqus #OpenSees #OpenSeesPy #FiniteElementAnalysis #StructuralEngineering #NonlinearAnalysis #SteelStructures #Simulation #Python #VerificationValidation

I am absolutely thrilled and honored to announce that our Marie Skłodowska-Curie Actions (MSCA) Postdoctoral Fellowship proposal received an extraordinary score of 99.6%! This milestone is the culmination of months of intense dedication and a truly collaborative effort. I owe a debt of gratitude to Dr .Said Elias , my supervisor Professor Francesco Clementi, and Professor Francesca Roscini, whose tireless, line-by-line guidance and mastery in research leadership were instrumental in our success. Their commitment to excellence and our shared vision pushed this project to its highest potential, and I am incredibly proud of what we have achieved together. I cannot wait to begin this next chapter at Università Politecnica delle Marche in Ancona, Italy, and turn this ambitious proposal into impactful research.
