Blast, Explosion & Impact

It’s impossible to predict many of the hazardous events that can occur in buildings: gas leaks, terrorist attacks, an object impacting a building happen without warning, to name a few. And because accidents can’t always be prevented, building designers, city officials and administrators need to take the possibility of these events into account when they are designing and building a new structure. Designing a building with these threats in mind can improve the structural integrity of the building, and it can also create a more safe and comfortable environment for those who use the structure on a daily basis.

In many disaster scenarios, destruction is so severe that reconstructing the event is difficult. But the knowledge gained from piecing together what happened can benefit designers and engineers. ANSYS software allows engineers to virtually model various structures and test the impact of environmental and destructive forces as many times as needed to completely understand the effects of a disaster on a structure.

Through virtual modeling, designers can learn not only what happens to a structure when disaster strikes, but why. Consider this example: A portion of a building collapses when hit by a vehicle. Multiphysics insight into the development of the disaster can provide guidance on how structures can be improved to keep survivors safe — such as modifying ventilation and fire suppressions systems — and strengthened to survive future events. The unequalled depth and unparalleled breadth of simulation software from ANSYS offers engineers many opportunities to optimize building designs to protect them from known yet difficult-to-predict dangers.
