IS 1893:2016 (Part 1) — The seismic zone architecture divides the sub-continent into Zones II through V based on historical seismicity, fault proximities, and geo-tectonic strata.

Base Shear (VB) = Ah × W. Ah derived here assumes the conservative plateau value of Sa/g. Exact engineering requires interpolation against spectrum curves via iterative structural modal analysis.

Common Questions

1
What is the Importance Factor (I)?

The importance factor (typically 1.0 or 1.5) accounts for the criticality of the building; hospitals and power plants have higher importance factors than residential buildings.

2
How many seismic zones are in India?

As per IS 1893:2016, India is divided into four seismic zones: II (Low), III (Moderate), IV (High), and V (Very High).
