两铰拱与三铰拱试验装置

Two- & Three-Hinged Arch Apparatus — Structural Engineering Lab Equipment

Arches carry load mainly in compression, and the horizontal thrust at the springings is what students need to measure and explain. We offer a three-hinged semicircular arch, a two-hinged arch with thrust measurement, a convertible two- and three-hinged model, a parabolic arch on load cell supports and a computerised arch with a moving load trolley. Arch shape, how thrust is read and whether you teach influence lines decide the choice. Rolling-load experiments link the theory to bridge loading in BS EN 1991-2, and member checks follow BS EN 1993-1-1.

How to specify

Choose a convertible model if one rig must cover both two- and three-hinged cases.
Load cells at the springings save time compared with balancing thrust by weights.
A moving load trolley is worth adding if influence lines are on the syllabus.
