Wave Problems

Embedded steel frame concrete blast walls can effectively counteract and dissipation the air-blast wave of the explosion. By contrast widely recognized air-blast wave empirical formula to verify the feasibility of the method of explosion load simplify model numerical simulation calculate the shock wave problems by using the explicit finite element software ANSYS/LS-DYNA and keywords *LOAD_BLAST. Obtained, The results of simplified explosion shock wave load by *load_blast have small difference with the actual explosion model; The destruction of the wall are mainly shear and brittle failure; The ability of Embedded steel frame blast wall resist air-blast wave significantly greater than other wall.
