Blast Time History Analysis Steel Structure
First Steps with RFEM
Description
Blast loads from high energy explosives, either accidental or intentional, are rare, but may be a structural design requirement. These dynamic loads differ from standard static loads due to their large magnitude and very short duration. A blast scenario can be carried out directly in a FEA program as a time history analysis to minimize loss of life and evaluate varying levels of structural damage.

Modal Analysis | Adding Masses
If you want to consider other loads as masses in addition to the static loads, you can do it for nodal, member, line, and surface loads. This can be done by selecting Mass as a load type when defining the load of interest. For such loads, it is possible to define a mass or mass components in the X, Y, and Z directions. For nodal masses, you also can specify moments of inertia X, Y, and Z in order to model more complex mass points.
