    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.

    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.

    Hi,

    Substitute frame method is used for the analysis of complex structure I.e multi-storeyed building because analysis of multi-story building is very complicated and long calculations needed. Substitute frame method used for sudden analysis and gives approximate values.

    The moment distribution method is used for the analysis of applied loads on the structure in the substitute frame method. This method is generally used to determine the vertical loads and horizontal loads. Vertical load is a combination of live load and dead loads

    This method is applied only or vertical loads.

    Dead loads include self-weight of slab column and beams which is analysed in substitute frame method.

    In this method, the beams which are at floor level as well as the columns above the floor and below which are situated at the fixed far end will be e analysed. In some cases the bending moment is not distributed over the far end, thus the moment is computed independently at each floor and retained on that floor for further analysis.

Which pressure us higher in retaining wall, water or soil?

    In technical terms, Above the Water table, Pressure exerted by water on retaining wall = 0.5 K.H^2 K = coefficient of earth pressure H= vertical height of wall. Total stress = effective stress + pore water pressure. Earth pressure due to soil: Total stress = effective stress.  

    In technical terms,

    Above the Water table,

    Pressure exerted by water on retaining wall = 0.5 K.H^2

    K = coefficient of earth pressure

    H= vertical height of wall.

    Total stress = effective stress + pore water pressure.

    Earth pressure due to soil:

    Total stress = effective stress.

    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
