In a pony truss the deck runs between two trusses that are not connected overhead. Users have an open view, and the top chords are restrained laterally by U-frames formed by the deck cross-beams and verticals.
Typical considerations
- Lateral stability of the top chord governs much of the design.
- The truss height often doubles as the parapet, which simplifies the railing.
- Segments are usually compact enough for road transport.
Information we need
Clear span, clear width, design code, deck type, parapet requirements and any limits on structure depth below the deck.
Final member sizes, details and specifications are determined by the engineer of record for each project. This page describes general practice and does not replace project-specific engineering.
