ST 332 PARABOLIC ARCH, Fixed Ends
GENERAL DESCRIPTION

    This equipment is used for measurement of horizontal thrust and end fixing moments of the abutment for comparison with model analysis and simplified theory. It is to be used with ST300 Universal Structural Frame (separately supplied).

    A parabolic arch has one end pivoted on a moment support and fitted with an arm for applying and measuring moments and rotations.  The other end is pivoted in ball bearings on a horizontal force support. Load hangers and weights are attached to the arch. Load hangers are used for measurement of horizontal thrust and fixing moment.
