quick overview :

Parabolic Arch With Fixed Ends

Technical Description:

• Apparatus to investigate the horizontal thrust and fixing moments of a steel parabolic arch
• To enable the calculation of influence lines
• Apparatus to consist of steel parabolic model arch
• 1.0metre span, 0.2metre rise
• To have springings with precision bearings installed
• Horizontal thrust measured by precision load cell
• Load to be applied using calibrated weights on vertical equi-spaced chains and hangers
• Ability for model analysis work to be undertaken using pins at hanger joints and dial gauge
• Must be used with universal Frame and Stand (sold separately)
• Must be used with Interface (sold separately)
• Comprehensive instruction manual provided

Experimental Capabilities:

• Measurement of end fixing moments and comparison with simplified theory
• Comparison of theoretical and experimental horizontal thrust
• Derivation of influence lines of the redundancies by direct measurement
• Derivation of influence lines of the redundancies by model analysis
