Steel arches can be designed as truss, box, or plate arches. Truss arch bridges are particularly suitable for large spans with excellent economy and structural efficiency.
Truss variations include Pratt, Warren, K truss, and sub-truss forms - each offering distinct mechanical and economic advantages.
The main load-bearing member primarily resisting axial pressure with some bending moment. Available in box, pipe, or truss configurations with truss type offering superior span capacity and economy.
Transfer component transmitting deck loads to arch ribs. Available as rigid (steel pipe/section) or flexible (high-strength wire) configurations with various elevation arrangements.
Absorbs arch thrust in non-thrust designs, available as rigid or flexible configurations.
Provides transverse stiffness and stability with various configurations including one-word, K-shaped, X-shaped, and meter-shaped braces strategically placed along the span.
