Do you know different Parts of The code IS 1893?

​IS 1893 (Part 1): 2016 – General Provisions and
Buildings
​What it covers: This is the master standard for buildings. It defines the seismic zone map of India (Zones II, III, IV, and V), design spectrum , importance factors (I), response reduction factors (R), and the calculation of design horizontal seismic coefficient and base shear
​The 2016 revision fundamentally altered calculations by shifting focus to cracked section properties (using 35% moment of inertia for beams and 70% for columns) and redefining story drift checks.

​IS 1893 (Part 2): 2014 – Liquid Retaining Tanks (Elevated and Ground Supported)

​IS 1893 (Part 3): 2014 – Bridges and Retaining Walls

​IS 1893 (Part 4): 2015 – Industrial Structures Including Stack-like Structures

​IS 1893 (Part 5): – Dams and Embankments (Note: Provisions for hydrodynamic pressure and seismic coefficients on gravity dams link closely with this section and Part 1).

MPSC सरळसेवा new Pattern batch 2026

​The Idea:

Regular concrete is great under compression but terrible under tension. By introducing high-strength steel tendons that are pulled tight before (or after) casting, we put the concrete under a permanent state of compression. This pre-compression counteracts the tensile stresses caused by external loads.

​Key Takeaway:

Pre-stressing eliminates cracking, allows for longer spans, and results in thinner structural members.

MPSC सरळसेवा new Pattern batch 2026

Schedule -29 June

Time- 6:30 PM
Subject -Engineering Hydrology-Infiltration

The Idea:
When dry sand comes into contact with a small amount of moisture (around 4% to 6% by weight), a thin film of water forms around the sand grains. Surface tension pushes the particles apart, causing a massive increase in volume—sometimes up to 20% to 30%.

​Practical Impact:
If you measure sand by volume (volumetric batching) without accounting for bulking, your concrete mix will end up starved of sand and structurally weak. Completely saturated sand shows zero bulking.

@macedhule

​The Idea:
In a concrete beam, we want the steel to fail before the concrete does.

​Under-reinforced:
Steel yields first. This gives ample warning (cracking and deflection) before structural failure.

​Over-reinforced:
Concrete crushes suddenly without warning. This is a catastrophic, brittle failure.

​Key Takeaway:
Codes like IS 456 strictly prohibit the design of over-reinforced sections to ensure public safety.
