Get Started in OpenSees with STKO

From 0 to nonlinear static and dynamic analysis of 3D frame structures in just a few months with OpenSees and STKO.

The purpose is to introduce OpenSees and STKO from the very basics. The course is oriented towards teaching OpenSees using STKO to visualize the processes, functioning, and outputs of OpenSees. The end result will be a complete series of recorded webinars that will set students and potential users up for success. By the end of the 20 classes, attendees will have received an overview on 3D frame structure modeling in both reinforced concrete and masonry, and performed linear, nonlinear, static and dynamic analyses on the models.

The webinars will be composed of three parts: a presentation session of 30 mins, a Q/A session, and an exercise to be carried out online on a new forum thread opened and curated each week specifically for the class. After two introductory classes, the course will start with a model overview, while each following webinar will address a specific single topic necessary for understanding OpenSees and STKO. Towards the end of the program, several classes will show practical examples using models. When the course is over, these specific, short, manageable webinars on single topics will remain on the site for beginners to access in the future.

Introduction to OpenSees
Introduction to the “Get Started in OpenSees with STKO” course...
-What is OpenSees: history, development, logic, components, use and applications for simulating the response of structural and geotechnical systems subjected to earthquakes.
-Tcl basics to use OpenSees with STKO.
-References and resources for further study.
Prerequisites: Concepts of Finite Element Modeling
Materials and Resources: Powerpoint
References and links to OpenSees resources and Tcl scripting basics provided in the powerpoint presentation. utils0.tcl - utility file for unit system setup and conversions Click here to access the course forum Click the title to view the youtube recording of the course.
Exercise: ex0.tcl - tcl basics to tryout in the Python interpreter, ex1.tcl - Fixed beam with distributed load example, ex2.tcl - Fixed portal frame with distributed load example
Homework: Choose your own analytical problem to recreate in tcl, set up your unit system and run it in STKO by plotting the relevant results.
