1st BAU-PROTECT 2004 Workshop

The first BAU-PROTECT workshop

"Structural Structures Subjected to Impact and Blast Loads"

took place on October 27 and 28, 2004

at the Fraunhofer-Institut für Kurzzeitdynamik, Ernst-Mach-Institut (EMI), Freiburg

The BAU-PROTECT workshop was the first event on the protection of building structures against impact and explosive loads at the Fraunhofer Ernst-Mach Institute on 27 and 28 October 2004. It was jointly organized by:

the Fraunhofer Ernst-Mach Institute
the Bundeswehr University Munich
the Military Technical Center for Protection and Special Technology (WTD 52)

Main topics

Terrorist attacks

The destruction of buildings and their facilities by terrorist attacks can result in enormous personal injury and property damage. The BAU-PROTECT workshop provided fundamentals on this topic – from risk analysis to damage and its structural prevention.

Analysis of load-bearing behavior, damage and failure

Analyzing the behavior of existing building structures under dynamic loading is used for the structural design and retrofitting of buildings and building components. BAU-PROTECT presented options for assessing the load-bearing behavior of dynamically loaded building structures and their residual load-bearing capacity after a damage event.

Special calculation methods

Fluid and structural dynamic calculation methods are used to analyze the causal chain of structural loading and structural behavior of damaged structures. These methods allow for the realistic and detailed simulation of the temporal development of loading and reaction processes. This includes the recording of shock wave processes, severe deformations up to failure, and post-failure behavior. Simplified calculation methods for determining the load-bearing capacity and designing components under dynamic loading were also discussed.

Hazard and risk

Potential hazards to buildings and their potential impacts are often not recognized or misjudged. The organizers introduced these complex problems and provided guidance on adequate risk analysis. Computer-aided methods based on both empirical and theoretical models were also presented, serving to facilitate efficient risk analysis.

Protection technologies and security technology

In many cases, preventative or retroactive structural protective measures help reduce or even prevent the extent of damage caused by dynamic impacts on buildings. In addition to structural protective measures, these include, among other things, necessary safety distances and rules of conduct. Another topic of the workshop was which specific measures and safety concepts are suitable for which problems.

Special testing methods

Testing structural components for their protective effectiveness requires special experimental methods. These and the special test equipment used were presented in the workshop.
