Two-Hinged Parabolic Arch
Two-Hinged Parabolic Arch enables direct measurement of the horizontal abutment thrust using a simple model for study and comparison with theoretical analysis.
Two-Hinged Parabolic Arch. The equipment allows direct measurement of the horizontal component of the abutment thrust of a two hinged parabolic arch by using a simple model. It is to be used with ST300 Universal Structural Frame (separately supplied).
A parabolic arch of uniform cross-section has one end of the arch on a fixed hinged pin and the other is on bearings on a horizontal force support.
The horizontal movement of the roller end is monitored by a dial indicator. Measurement of horizontal thrust by the roller end is by using a pulley and a load hanger.
Instruction manual is also included.
- Demonstration of the characteristics of a two-pinned arch
- Examination of the relationship between applied loads and horizontal thrust
- Comparison of behavior to simplified theory
