Why helical reinforcement gives better strength than ordinary columns?

    The small dia reinforcement wrapped around the main or longitudinal reinforcement of columns, restraining the lateral expansion of the concrete under compression and thus strengthening the column.

    The small dia reinforcement wrapped around the main or longitudinal reinforcement of columns, restraining the lateral expansion of the concrete under compression and thus strengthening the column. Columns with one helical reinforcement take more load than that of tied column due to additional strength of spiral.

    Helical reinforcement can protect columns/piles against seismic loads.

    Both have different properties & a separate cost which describes below.

    steel

    • As compared aluminium,steel have less corrosion resistance
    • Steel are chiper than aluminium
    • Steel give lesser malleability and elastic properties than aluminium
    • In weight steel have higher weight
    • Steel is tough & harder than alluminium
    • Generally we use steel as a reinforced member in concrete structures
    • Esay to weld with other structural components.

    Aluminum

    • Higher corrosion resistance
    • Higher cost
    • Higher
    • malleability and elastic properties
    • Lesser weight
    • Generally we not use in concrete
    • Difficult to weld
    • Aluminum is soft metal compare to steel.

     

    We are generally use steel as a reinforcement.

    We doesn’t use aluminium because of soft metal property

Hi. I am an architect and I’d like to hear your advise. Can this type of brick bond be used for a load bearing wall? I think that this zigzag form makes the wall stronger, but will it be enough? I ...

    In masonary work, we used usually 1:4 cement-sand mortar of compressive strength 3.8N/mm2. The compressive strength of one brick of standard size is 11.12N/mm2. The compressive strength of brick masonry is 2.5 N/mm2.  Thanks.

    Bar bending schedule (BBS) is a comprehensive, detailed list of reinforcement bars to be used in an RCC construction along with their number, location, mark, type, size, lengths, details in correspondence with the drawings. It also includes the timing for the bending of each bar, and that is why it’s called a bending schedule.

    Bars are needed to be bent in order to give them the desired reinforcement shape. Stirrups and anchorages are two places where bar bending is compulsory. In addition, when we need to join bars, we might want to bend them on the ends before welding or fastening.

    BBS also gives a clear and logical understanding as to how much bars of what sizes will be needed to be procured and bent by what time so that no delay, all procurement is done with minimal transport expenses, and all bending is done with minimal machine and labor costs.

    T-beam is simply rectangular beam cast monolithically with the slab.

    Advantage os T-beam over ordinary beam:-

    1. T-beam casting with slab as we know so Its flange takes compressive stress and that mean It will resist more sagging moment of beam.
    2. Depth of beam is reduced as compare to ordinary beam so better headroom advantage.
    3. Over longer span T-beam is used rather than ordinary beam for reducing the deflection of beam.

    Reinforced concrete deep beam is defined as that members with clear spans in equal or less than four times the overall member depth or regions of beams that are loaded on one face with concentrated loads within twice the member depth from the support and supported on the opposite face so that compression struts can be developed between the loads and supports.

    Here if the matter comes about higher modulus of elasticity between rubber or steel then we can say steel is more elastic than rubber.

    Here if the matter comes about higher modulus of elasticity between rubber or steel then we can say steel is more elastic than rubber. We know that young’s modulus is the ratio of stress to the strain. Therefore, for a given stress, the strain produced in steel is much smaller than that produced in rubber. This implies that Young’s modulus for steel is greater than that for rubber.
