  2. Eyebar - Wikipedia

    en.wikipedia.org/wiki/Eyebar

    The remaining nine elements are only in tension and are composed of eyebars. Shear and bending forces are accommodated completely within the deck structure. In structural engineering and construction, an eyebar is a straight bar, usually of metal, with a hole ("eye") at each end for fixing

  3. Rebar - Wikipedia

    en.wikipedia.org/wiki/Rebar

    D500N12 is deformed bar, 500 MPa strength, normal ductility and 12 mm nominal diameter – also known as "N12" Bars are typically abbreviated to simply 'N' (hot-rolled deformed bar), 'R' (hot-rolled round bar), 'RW' (cold-drawn ribbed wire) or 'W' (cold-drawn round wire), as the yield strength and ductility class can be implied from the shape.

  4. Rebar spacer - Wikipedia

    en.wikipedia.org/wiki/Rebar_spacer

    The engineering study of every reinforced concrete construction, whether it is a building, a bridge, a bearing wall, or another structure, dictates the positioning of steel rebars at specific positions in the volume of concrete (predicted concrete cover of steel reinforcement bars). This cover varies between 10 mm and 100 mm.

  5. Shear strength - Wikipedia

    en.wikipedia.org/wiki/Shear_strength

    In structural and mechanical engineering, the shear strength of a component is important for designing the dimensions and materials to be used for the manufacture or construction of the component (e.g. beams, plates, or bolts). In a reinforced concrete beam, the main purpose of reinforcing bar (rebar) stirrups is to increase the shear strength.

  6. Shear force - Wikipedia

    en.wikipedia.org/wiki/Shear_force

    area of the bar in mm 2 = (12.5 2)(π) ≈ 490.8 mm 2 0.8 kN/mm 2 × 490.8 mm 2 = 392.64 kN ≈ 40 tonne-force 40 tonne-force × 0.6 (to change force from tensile to shear) = 24 tonne-force. When working with a riveted or tensioned bolted joint, the strength comes from friction between the materials bolted together. Bolts are correctly torqued ...

  7. Expansion joint - Wikipedia

    en.wikipedia.org/wiki/Expansion_joint

    An expansion joint is designed to allow deflection in the axial (compressive), lateral (shear), or angular (bending) deflections. Expansion joints can be non-metallic or metallic (often called bellows type). Non-metallic can be a single ply of rubberized material or a composite made of multiple layers of heat and erosion resistant flexible ...

  8. Rivet - Wikipedia

    en.wikipedia.org/wiki/Rivet

    The holder up or holder on would hold a heavy bucking bar or dolly or another (larger) pneumatic jack against the round "shop head" of the rivet, while the riveter (sometimes two riveters) applied a hammer or pneumatic rivet hammer with a "rivet set" to the tail of the rivet, making it mushroom against the joint forming the "field head" into ...

  9. T-beam - Wikipedia

    en.wikipedia.org/wiki/T-beam

    Unlike an I-beam, a T-beam lacks a bottom flange, which carries savings in terms of materials, but at the loss of resistance to tensile forces. [5] T- beam designs come in many sizes, lengths and widths to suit where they are to be used (eg highway bridge, underground parking garage) and how they have to resist the tension, compression and shear stresses associated with beam bending in their ...
