    CORROSION refers to an electrochemical reaction between a metal and its environment. Steel will readily rust unless it is coated. Corrosion occurs when steel reacts with chloride ions (Cl-), CO2 in the presence of a toxic environment. Thus, corrosion is uneven erosion/pitting of metal surface due to intense rusting and is also harmful to the service performance of rebar.

    There are many ways of reducing the risk of corrosion-related distress in concrete. The first defencing layer is concrete, which should be thick and dense. Also, the cracks should be minimized. The concrete cover should be used appropriately.

    An additional measure for corrosion-resistant is that corrosion inhibiting admixtures should be used. Epoxy coatings should be done on rebar, which acts as a physical barrier and also isolates the steel from oxygen, moisture, and chloride ions (which are the three primary elements needed for corrosion to occur).

    Reinforced soil:

    Meaning of Reinforced soil: Reinforced soil is simply a combination of compacted earth fill with the tensile reinforcement for creating an earth structure. 

    Advantages of reinforced soil:

    1. Less quantity of earth fill is required.
    2. The construction can be directly done on the soft ground.
    3. The structures can be quickly built as compared to any other conventional methods.

     Limitations of reinforced soil:

    • One of the biggest doubts about reinforcing soil is its durability.

    Thank You.

    This is one of the most popular questions.

    Basically, building codes typically require that the structure is wall roof floor, the roof is fire-resistant.

    The standards set forth by the International Building Code (IBC). fire resistant Wallis designed for a definite time period.

    According to ‘Commercial drafting and detailing book’, a one of our fire rated wall consists  2 x 4 studs spaced 16 inches from the centre of one stud to the centre of the next.

What is the difference between a load bearing structure and a frame structure? How load is transferred in load bearing and framed structures?

    No. Load Bearing Structure Frame Structure
    1. Almost all the walls are load bearing walls. None of the wall are load bearing. They serve the same purpose as partition or screen.
    2. Almost all the should be provided with foundation None of the walls are provided with any type of foundation. Walls do not go below the plinth beam.
    3. Load bearing walls are taken deep into the subsoil foundation. Only column are taken deep into subsoil and provided with foundation footing.
    4. Any load bearing wall should have minimum thickness of 200 mm. Exterior wall subjected to weathering elements are generally 200 mm thick. All other wall can be 100 mm thick or even thinner.
    5. Wall are usually constructed of bricks or stone. Column supporting beam supporting slab are all of R.C. C.
    6. In a multi-storeyed building for every wall in the floor above there must be a corresponding wall in continuation in the floor below to support it. There is no such necessity. As none of the walls are load bearing. Every floor may have wall independent of the one below it.
    7. In a multi – storeyed building the thickness of the wall increase as we descend from a floor above to one below it. These walls do not take the load and need not be thicker. They may not even continue in the floor below.
    8. A load bearing wall once constructed shall remain in position and should never be dismantled in full or part. The wall of framed structure can be displaced at will as they are lighter and non load bearing.
    9. This type of construction does not favor toomany openings for windows, doors, ventilation etc., in the ground floor as required for show room etc., as the load bearing length of wall is considerably reduced. The space between column can remains as open space as the case with multi – storeyed residential flats where the ground floor is left with no walls for easy parking of vehicle.
    10. In case of multi – storeyed buildings, the room area is reduced as we go down due to thicker walls. Thickness of wall remains uniform, therefore the carpet area in any floor remains the same.
    11. Plans of the different floors must be the same. Very little changes are only possible between one floor and the one above. Plans of different floor are independent of each floor. The ground floor may have a commercial complex, first floor an office or a bank and second floor onward of residential complexes of different types of plans and function within the same building.
    12. May not withstand seismic forces and other forces and other type of vibration because composed of different blocks as bricks and stones being bonded together. More rigid and withstand seismic forces because of the entire frame of column, beam and slabs act as one unit of R.C.C.

    Aditya,

    Here you are asking about Life Cycle Assessment (LCA) of structure.

    The life span of structure will vary according to the type of structure.

    There is no formula available to calculate the life span of any structure.

    Different parameters we should take into mind while doing a calculation of life span of structure, they are as follows;

    Building Construction Material:

    • RCC structure

    Structural Design:

    • Mostly influencing parameter.
    • Vary as per Building Construction Material.

    The locality of structure construction: E

    • Earthquake-prone area
    • HFL (High Flood Level) zone

    Height of structure.

     Kindly noted that I have attached one photo of the life span of various structures.

    Back Sight: Backsight is simply a first reading which is taken after setting up the instrument.  Why the backsight is also called plus sight: Only because the reading is taken of known elevation to continue taking foresight reading.  Thank You.
