How do I remove a load bearing wall and extend (extension only on one side) the ground floor on a g+1 structure, and what will be the costing of this procedure?

    A floor plan should be provided with sections showing column and beam layout. But it will be better if you hire a contractor.

    The castellated beam is a modified steel beam. In which the beam is cut in the central web portion were no great force is present.

    The castellated beam is a modified steel beam. In which the beam is cut in the central web portion were no great force is present.

    Cut near to neutral axis of the beam where we required less amount of material mass to resist various force.

    The opening shape may be hexagonal, rectangular, circular, etc.

    Due to opening in web we get some benifit

    • Saving in material
    • Lighter weight
    • Due to increased depth allowed, we get more strengthen beam
    • Good aesthetic view
    • Esay handle with roof febrication work.

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

    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.

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.

How to calculate length of overlap for reinforcement steel?

    Lapping of reinforcement is usually done where minimum bending stress is required. In general, lap length is 50d which means 50 times the bar diameter is provided if both bars are of same diameter. Lap length in tension: The lap length including anchorage value of hooks shall be For flexural tensionRead more

    Lapping of reinforcement is usually done where minimum bending stress is required. In general, lap length is 50d which means 50 times the bar diameter is provided if both bars are of same diameter.

    Lap length in tension:
    The lap length including anchorage value of hooks shall be

    For flexural tension – Ld or 30d whichever is greater is considered.
    For direct tension – 2Ld or 30d whichever is greater is considered.
    The straight length of lapping of bars shall not be less than 15d or 20cm.

    Lap Length in Compression:
    The lap length is equal to the development length calculated in compression but not less than 24d.

    For Different Diameter Bars:
    When the bars of different diameters are to be spliced, the lap length is calculated considering the smaller diameter bar.

    Basically, shear force is the combination of flexural compression which result as C and tends to form an inclined thrust line known as arch. For example consider a simple strut and tie model.

    NαVcotθNa=αVcotθ

    Shear force is the product of shear stress and area. Thrust line can also affect the stability.

    There could be broadly two types of corrective treatment: a.

    There could be broadly two types of corrective treatment:

    a. Support the concrete column with adjoining steel column ( an ISMB section will be better.), for ordinary house 12 feet height column, suggested steel ISMB is 250X 150 mm section.

    b. if column is found reparable, it is renovated with ‘ Jacketing ‘ around it. That is, scarp old peeling plaster, reach to reinforcing material, apply corrosive preventive liquids available from a good hardware store. Then, tie new reinforcement over the old reinforcement. Over it place 4-inch fresh cement concrete with aggregate of 12mm. Of course, steal or wooden scaffolding will be required.

    It will increase the size of the column but will give strength to it.

    BUT Note: if the column has already buckled down.. it is advisable to immediately get the help of an engineer and show him the site because if the column collapses, building or roof over it is in danger.
