    Gopal Mishra

    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.

    lap length is required when bars placed short of their required length (due to nonavailability of longer bars) need to be extended. lap length is to be provided to safely transfer the load. Development length is provided to transfer the load from steel to concrete. It is also known as anchorage lengRead more

    Stirrups are mainly provided for holding the main reinforcement of beam. It prevents the buckling of beam and also protect the RCC structure during seismic activity. Stirrups providing protection against flexural and shear failure as shown in figure.

    Basic difference is retaining wall is designed to resist backfill earth pressure and breast wall is resist for natural earthen slope of hilly area

    In hill. When road is construct, at that time we need to cut-off some portion of hill and basically we construct two wall one is breast wall which is on hill side of the road to give stability of hill slop and another one is retaining wall which is construct on valley side of road which wall have backfill pressure plus road pressure on backfill so we need to design retaining wall for that backfill & surcharge .

    See figure for different between retaining wall and breast wall.

    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

    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.

    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.
