    Study Notes

    Lay Out Rencana Jembatan (Bridge Design Layout)

    • Struktur Jembatan: The bridge design includes a main arch-shaped truss, transverse beams, and supporting elements like bracing and footings.
    • Dimensi: Measurements of various components are labeled. Dimensions are given in meters (m).
    • Gelagar Melintang (Transverse Beams): These are cross beams supporting the bridge's deck.
    • Bracing Bawah (Lower Bracing): A portion of the structural support system located below the truss.
    • Pelat Beton (Concrete Slab): A concrete layer forms the bridge deck.
    • Lampu (Lighting): Placement indicated for lighting fixtures.
    • Railing (Guardrails): A safety feature shown on the design.

    Profil Gelagar Melintang (Transverse Beam Profile)

    • Profil W 8x15: The specific steel beam profile used in the bridge design.
    • Mutu Baja A50: The type of steel used, with specific yield strength (fy) and ultimate strength (fu) values.
    • Properties of W 8x15: Detailed data on the beam's properties, including area (A), thickness (Tw, tf), depth(d), width (bf), moment of inertia (Ix,Iy), radius of gyration (rx,ry) and section modulus (Sx, Sy) All values are provided in both inches (in) and millimeters (mm).
    • Berat Profil (Weight): Calculations show the per-meter weight of the beam (in kN/m).
    • Sumber Data: Data sourced from the AISC Steel Construction Manual. Page numbers (32 and 199) provide specific table references.
