The Parabolic Arch Bridge Apparatus, manufactured by Atto Labware, is an educational trainer designed to study the behavior of parabolic arch bridges under different loading conditions. It allows students to investigate reactions, thrust, bending moments, and the effect of varying loads, making it ideal for engineering colleges, technical institutes, and vocational training centers.

Educational Objectives
Students will be able to:

• Understand the structural behavior of a parabolic arch bridge.

• Study horizontal thrust and reactions at supports.

• Analyze the effect of concentrated and distributed loads.

• Observe bending moment distribution in arch structures.

• Verify theoretical analysis through practical experiments.

Performance Measurement

• Demonstration of load effects on a parabolic arch bridge.

• Measurement of support reactions and horizontal thrust.

• Observation of deflections and bending moment variations.

• Validation of theoretical calculations with experimental data.

• Analysis of arch bridge stability and structural response.

Panel and Instruments / Components
