Abstract：When the centre of explosion is at one side of structure，only part of the structure will subject to explosion load. In this condition，the inner stress and the types of failure of the structure will change greatly. Load distribution is discussed for side blast. The calculation of load is given out. A damping action is used to replace the interaction between structure and the surrounding soil. So the soil-structure interaction is inserted into the controlling equation. And then the exact solution can be obtained by solving the equation. Method is obtained to calculate reaction of the structure when the centre of explosion is in arbitrary position far enough from the structure. And the distribution of displacement and maximum moment are got for side blast.
