State-of-the-art dynamic analysis and explosion protection of buildings demands customized and often integrated use of a range of engineering methods. The scaled distance can give a first indication if global structural modes, e.g. bending, or local failure modes such as breaching or shear failure have to be considered. Engineering tools are helpful for quick prediction and design of buildings and facilities. They can analyze simple geometries, also as part of a complex construction, if the failure mechanisms are well understood.
Two distinct examples of such PC tools for different loading regimes are highlighted and explained: a physically based single-degree-of-freedom analysis program, using similarity methods for transition from actually tested to arbitrary component geometries and an empirically based analysis tool for breaching predictions for contact detonations. Far more powerful, versatile but also expensive in terms of expertise and time requirements are finite element simulations with appropriate material models. Basic principles and key material descriptions are described. The course finally gives an outlook on the integration of these methods for the efficient assessment and design of urban areas regarding vulnerability, risk and resilience.

ABOUT THE INSTRUCTOR
Professor Werner RIEDEL is the Deputy Head of the Impact Physics Department of Ernst-Mach-Institut (EMI), Germany. He received degrees in Mechanical Engineering from the Technical Universities of Munich (1994) and Compiègne, France (1996). At EMI he specialized in numerical modeling of materials and components under dynamic loads.
In 2000 he received the doctoral degree at the University of the German Armed Forces at Munich. Selected project examples are the direction of the ADAMMO study for ESA, (material models for orbital debris impact on ISS) and the VITRUV project (urban security) in EU-FP7. Dr. Riedel authored 103 scientific publications from 1996 to 2017.
He was invited as Visiting Professor by Tokyo Institute of Technology in 2006 and 2010, and is Professor at Furtwangen University in Security & Safety Engineering since 2011. He is holding the position of a Visiting Associate Professor at NTU-CEE.
