    Study Notes

    Cable Suspension Bridge Analysis

    • Concentrated Load Analysis: Examines the behavior of cables in suspension bridges when a single, concentrated force (like a vehicle) acts upon them.
    • Uniformly Distributed Load (UDL) Analysis: Studies how the cables respond to a load that is spread evenly across a certain length of the bridge deck.
    • Cables Over Pulleys: Investigates the forces and stresses experienced by cables when passing over supporting pulleys.
    • Cables with Saddles: Analyzes the performance of cables that are secured by saddles - specially designed structures used for supporting and adjusting cable tension.

    Two & Three Hinged Arches

    • Static Loads: Focuses on the effects of stationary forces applied to two and three-hinged arches.
    • Bending Moment: Calculates the internal moment created within the arch due to applied loads, which can cause the arch to bend.
    • Radial Shear: Measures the force acting perpendicular to the arch's axis, which tends to make it shear along its radial direction.
    • Axial Thrust: Determines the compressive force along the axis of the arch, which is essential for transferring loads to the supports.
