Abstract—Due to different accidental and intentional events like terrorist attacks related to important structures all over the world, explosive loads have received considerable attention in recent years. The design and construction of bridge to provide life safety in the face is receiving renewed attention from structural engineers. Analysis of highway bridges under blast loads requires accurate generation and application of blast loads and good understanding of the behavior of components of bridge. The purpose of this paper is to introduce some ideas about blast load generation method like pressure wave method, detonation simulation method, hybrid blast load method and multi-Euler domain method. Also verification of blast load results using hybrid blast load method and multi-Euler domain method included in this paper.
