According to the characteristic explosion of the vehicle bombs

the parameters of air shock wave in the vehicle bombs explosion near the surface are calculated in this paper.The elastic-plastic calculation method of blast resistant wall subject to equivalent loading is established.A type of assembling component structure of reinforced concrete and steel plate for the blast resistant wall is designed by using the method

and computational results are compared with results of the finite element method.Results show that the design loading of blast resistant wall is the fifth peak value pressure of air shock wave and have provided with economic worthiness by using the plastic deformation characteristic of the blast resistant wall.
