    The following steps should be considered when designing a truss:

    1. Selection of type and layout of the structure.
    2. Determination of loads on the structure.
    3. Evaluate internal forces and moments in the structural components.
    4. Selection of material and proportioning of members and connections for safety and economy.
    5. Checking the performance of the structure under service conditions, and finally perform the final review.

    Yes, if the columns are not verticle the load transfer which happens via column is not 100%. This affects the durability and life of the building. Due to this, there might be a risk of safety during calamities.

    The justification is given by the supervisor is not correct. To rectify the mistakes done during the casting of columns, the columns are plastered to make them look truly vertical.

    Mortar mix ratio i.e. proportioning of cement sand in mortar provides consistency in the performance and appearance of masonry construction. Proper proportioning of mortar ingredients helps in having the following advantages:

    • Uniformity of strength
    • Uniform workability
    • Uniform color
    • Uniformity of proportions and yields

    Mainly the proportioning of the cement and sand for mortar is conducted by volume proportioning compared to weight proportion.

    The types of cement mortar are in detail explained in the article below-

    The rebar spacing must be mentioned in the drawing. The drawing without rebar spacing is incomplete. This is because the rebar spacing is obtained during design calculation.
