| Abstract: | With the background of lateral stability of non-range-spacer through bowstring arch, analytical approxima-tions are derived in this paper using energy variational approach. Through an example, the effect of force in the hanger on lateral stability is examined. Finally, comparison is made between the method in this paper and common method used in engineering design. |
