Compute blast loading parameters for protective structural design per UFC 3-340-02. Input charge weight and standoff distance to determine peak overpressure, positive phase duration, impulse, and reflected pressure. Supports both free-field and reflected blast scenarios. Used for hardened structures, blast-resistant design, and protective construction.
Peak incident and reflected overpressure, positive phase duration, impulse, arrival time, and shock front velocity based on charge weight (TNT equivalent) and standoff distance.
What is UFC 3-340-02?
UFC 3-340-02 (Structures to Resist the Effects of Accidental Explosions) is the US Department of Defense standard for designing structures to withstand blast loads. It provides charts and equations for blast parameter estimation.
Can I use this for vehicle barriers or security design?
Yes. The blast parameters from this calculator are used in the design of blast-resistant buildings, vehicle barriers, protective walls, and other security-related structures.
