APPROXIMATE ANALYSIS AND OPTIMIZATION OF STIFFENED TIED ARCH BRIDGES

The stiffened tied arch bridge has a tie consisting of a stiff flexural member, which tends to distribute live loads uniformly over the arch. Various approximate methods for analyzing this system are presented, including maillart's method, a simplication of that procedure, the single-redundancy method, and an elastic foundation approach. Comparisons are made with a computer analysis to determine the accuracy of each procedure. Increased familiarity with this structure should lead to more frequent consideration of this type of bridge by designers. (Author/TRRL)
