Two-Hinged Arch Apparatus with Thrust Measurement
可测推力两铰拱试验装置
A two-hinged arch is indeterminate, and the usual lab method is to let the roller support spread, then push it back with weights. This 1000 mm span segmental arch with a 250 mm rise sits on a pinned and a linear-bearing roller support. A 0.01 mm dial gauge shows when the springing is restored, while nine hangers at 100 mm spacing allow influence line work.

Product Description 产品描述
A two-hinged arch is indeterminate, and the usual lab method is to let the roller support spread, then push it back with weights. This 1000 mm span segmental arch with a 250 mm rise sits on a pinned and a linear-bearing roller support. A 0.01 mm dial gauge shows when the springing is restored, while nine hangers at 100 mm spacing allow influence line work.
Highlights
- 1000 mm span segmental rib
- Linear-bearing roller support
- 0.01 mm dial gauge for restoring springing
- Nine hangers at 100 mm spacing
Applications
- Horizontal thrust of a two-hinged arch
- Statically indeterminate structure analysis
- Influence line for thrust
- Comparison with strain energy method
