Research Interests Earthquake Engineering Structural Dynamics Nonlinear Dynamic Modelling Techniques Steel Structures Self-Centering Systems Specific Research Interests and Activities Dr. Wiebe is developing tools and educating people to meet the structural engineering challenges of an urbanizing world. There are two main streams to his research: Developing economical ways of improving structural performance: this research identifies innovative ways of using traditional materials and construction methods to improve the resilience and sustainability of built infrastructure. There is a particular focus on developing self-centering steel seismic force resisting systems, such as controlled rocking steel frames. Developing appropriate structural modelling tools: this research enables more rational structural design and assessment through improved numerical modelling. While there is a particular focus on refined models that can simulate structural response up to collapse, simplified models are also being developed to provide design-level approximations of key response parameters.
