ARCH STRUCTUREEnchanted by their spectacular outlook, countless arch structures are constructed since time immemorial. The exceptional performance and unbelievabledurability of these structures have resulted in many successful applications;especially bridges, of striking aesthetic appearance being recorded across nearlyall continents of the world. Interestingly, many ancient and modern archstructures are found coexist and stand next to one another harmoniously atmany prominent locations of the world.
