    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.

    For reduced use staircases such as accesses to lofts, attics and terraces, the minimum width shall be 600mm. The minimum tread shall be 250mm excluding nosing and the maximum riser will be 175mm for all buildings except for internal staircases of apartments, which can be permitted upto 190mm.

    I will provide you a list which causes the building to collapse.

    1. Defective building design
    2. Faulty construction & More extra loads
    3. Failure of foundation
    4. Unexpected failure mode
    5. Soil liquefaction
    6. Demolition through explosives
    7. Earthquake
    8. Tsunami
    9. Typhoon and winds with high speed.
    10. Landslides or settlement of Sub-base soil due to over drainage.
    11. Soil with less bearing capacity.
    12. Errors in structural design.
    13. Inferior quality of cement and integrants is used.
    14. Use after the expiry of the life of buildings.
    15. Maintenance not done properly.
    16. Proper Foundation not provided.
    17. Less amount of reinforcement provided.
    18. Reinforcement corroded.

      Thank You.

Why we provide distribution Steel in slab?

    Distribution bars placed on the top of the main bar. Main reinforcement bars are used to transfer the bending moment developed at the bottom of the slab. Distribution bars are used to hold the slabs on either way and to resist the cracks and shear stress developed at the top.

    Redundant Truss: It is a truss that includes a maximum number of structural members more than the requirement. Using the equation of equilibrium, it is impossible to analyze. It is a statically indeterminate type of structure. Thank You.

    Murrum soil is the soil of humid tropical or equatorial zones. It is characterised by the deep weathered layer fom which silica has been leached. Thus, there is no humus, but an accumulation of aluminium and iron oxides and hydroxides. These soils are reddish in color & is imparted by the iron compounds. For building huts and paths, they are good materials, as it can be compacted easily to form hard surfaces.

    Murrum soil comes under laterite soil. Laterite is a soil and a rock type rich in iron and aluminium. Murrum soil is also referred as being a rock type but it is not a rock.

    The approximate density of murrum soil is 1.8 gm/cc.

    First of all you have to design that story building to provide reinforcement for all members such as slab ,beam,etc. by using different code such as IS etc.
