This remote short course will teach you how to use OpenSees and how to conduct non-linear seismic response analyses. The course will be an interactive and practical introduction to OpenSees modelling and analysis

You will learn how to model a simplified steel structure in 2D and conduct Eigenvalue, seismic pushover, and seismic time-history analyses.

The course is aimed at engineers/ professionals and Master’s level students with a structural engineering background who want to learn how to use OpenSees, one of the most potent tools for non-linear structural response analyses.

Structure and Teaching

The course will span over three, three-hour interactive sessions where you will be encouraged to ‘code along’ with the instructors as they take you through a set of practical examples.

You will be introduced to the fundamentals of the tcl coding language used in OpenSees

The training material includes step-by-step guides together with practice examples and solutions.

The course will be taught virtually by four PhD research students at UCL who together have over 15 years’ worth of OpenSees experience.

About the Speakers

Jonas Cels

PhD Candidate at University College London

11
Jonas is a PhD candidate at UCL, EPICentre who focuses on tsunami risk. Jonas is developing numerical tools to assess the response of structures subjected to tsunami loads using OpenSees. Jonas has used OpenSees to conduct both non-linear seismic and tsunami response analyses. 

Fernando Gutierrez Urzua

PhD Candidate at University College London

Fernando is a PhD Candidate at UCL, EPICentre. His current research focuses on the reliability assessment of passive energy dissipation devices used in the retrofitting of existing structures. He previously worked as a Structural Engineer for six years and has extensive experience with OpenSees. 

Maria Kontoe

PhD Candidate at University College London

11
Maria is a PhD candidate at UCL, EPICentre. Her research focuses on the multi-hazard vulnerability of RC structures including earthquakes and landslides. Maria uses Opensees within her research to model and analyze the nonlinear response of 3D RC structures against earthquake and landslide induced loads. She has extensive experience using both distributed and the lumped plasticity approaches in OpenSees. 

Sahin Dede

PhD Candidate at University College London

sahin
Sahin is a PhD candidate at UCL, EPICentre with expertise in fire and earthquake multi-hazard vulnerability. He is currently developing advanced numerical modelling tools to investigate the enhanced risk to reinforced concrete buildings under sequential fire and earthquake hazard events using OpenSees. He has more than four years of OpenSees experience with a breadth of knowledge in adaptive solution algorithms and plasticity approaches for nonlinear modelling and analysis.
