| Abstract: | Based on the flow theory and rigid-plastic idealized model, the constitutive law and governing condition for rigid-plastic analysis are determined. According to the upper bound and lower bound theory, themathematical expressions for finding the ultimate load by means of the linear programming approach are established. Taking a truss as an example, the process of calculation is illustrated. |

| Keywords: | ultimate load linear programming dual plastic pontential olclapse mechanism compatibility. |
