    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.

    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.

    The moment of the wall towards the backfill, in this case, the lateral earth pressure called a passive earth pressure.

    In the case of passive earth pressure,

    Major principal stress = lateral pressure

    Minor principal stress = vertical pressure

    In this case, soil exerts a pull on a retaining wall where the inner rupture plane called as a failure plane makes at (45- fi/2) angle with horizontal.

    At depth=0 , Rankines passive force= 0

    If q is a surcharge load acting on backfill, then lateral pressure = K.q applied throughout the depth of retaining wall.

    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.

    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.
