Utilizing the coupling characteristics of internal forces of statically indeterminate truss, the control model adjusting the working state of truss has been extended from single loading case to multiple loading cases. The load bearing states of the structure are more rational under multiple load cases by reducing the length of a few bars. A strategy of an initial selection for critical constraints is implemented to avoid the increasing calculation scale owing to multiple loading cases whose corresponding algorithm has been kept in the original scale of the single loading case. As a linear programming, the model gives a number of satisfactory computations of truss examples.
