Aim: Q1) Explain in detail about open foundation. --> The 'open' refers to the fact that the foundations are made by first excavating all the earth till the bottom of the footing, and then constructing the footing. During the early stages of work, the entire footing is visible and is therefore called an open…

Q1) Provide the empirical formula for Pile Load.  --> Piles transmit a load of a structure to competent sub-surface strata by the resistance developed from bearing at the toe or skin friction along the surface or both. The piles may be required to carry uplift and lateral loads besides the direct vertical load. For dividing…

Aim: Q1)Explain the design codal provisions for pile cap of metro viaducts in detail. -->A reinforced concrete slab or block which interconnects a group of piles and acts as a medium to transmit the load from wall or column to the Piles is called a Pile Cap. The Pile cap should normally be rigid so as to distribute…

Aim: Q1)Explain in detail the steps involved in calculation of the loads considered in piers. Answer:- Pier is the compression member of the bridge. They support the span (superstructure) of the bridge by transferring the load to the foundation. They are subjected to massive loads like Bi-axial moment in both longitudinal…

Q1) List factors of 4 loads for SLS G-I Combinations as per IRS. --> There are seven categories of load combination (G I, G II a, G II b, G II c, G II d, G III & G V) 'G' primarily stands for grouping where in G I we take all the normal Loading, this load is taken for designing the life of the structure.…
