Dr. Massimo Petracca
Managing Partner and Chief Software Developer at Asdea Software Technology
With a dual PhD in structural mechanics from the Polytechnic University of Catalonia and the University Chieti-Pescara, he is a well-known expert in micro modeling and computational multiscale homogenization and has extensive experience in software development for numerical methods and data visualization. His research focuses on the constitutive modeling of material failure in concrete, masonry, and composite materials through classical and advanced computational methods, and his research has been published in international journals and conferences. As a regular contributor to OpenSees code development, you can’t find a better person to give advanced webinars on OpenSees!

Short Course
Modeling RC Shear Walls in OpenSees and STKO
We get lots of requests for assistance on the various topics that concern the modeling of RC Shear Walls in OpenSees and STKO. We decided to create a short course to explain the main steps required to set up RC Shear Wall simulations. The course presents how to model RC Shear Walls using different approaches, from beams to shells and solid elements. Each class is dedicated to a particular approach, with the course culminating in a Round Table and Q&A. We hope you find the course recordings and files helpful!
