Abstract

The paper applies a new method based on block theory, stress analysis and linear programming to study the stability of a statically indeterminate 2-d block under arbitrary loads. The stability of keyblocks subjected to a range of directions of a fictitious loading or support force is analyzed using linear programming. Based on this optimization procedure, a keyblock can be classified as stable, unstable or potentially unstable. The range of loading force where a keyblock may be potentially unstable (uncertainty in stability) is affected by the indeterminacy of the force system and the angle of applied load. For a wide range of applied load angles, the uncertainty is small. Hence, the technique presented here would provide useful results for design.
