IS 1893:2016 vs IS 1893:2025 | Equivalent Static Method Comparison | Seismic Analysis Explained

Описание: In this video, we present a detailed comparison of the Equivalent Static Method (ESM) as per IS 1893:2016 and the latest IS 1893:2025 seismic code.
This lecture explains the major changes in seismic force calculation, including:

✔ Difference between Sa/g (2016) and normalized spectral acceleration (2025)
✔ Change from effective PGA (Z/2) to full hazard-based PGA (Z)
✔ Concept of uniform hazard response spectrum
✔ Impact of code changes on base shear calculation
✔ Applicability and limitations of the Equivalent Static Method
✔ Why IS 1893:2025 is more performance- and hazard-based

This video is extremely useful for:

B.Tech & M.Tech Civil Engineering students

GATE & ESE aspirants

Structural design engineers

Faculty teaching Earthquake Engineering

Professionals using ETABS / STAAD / SAFE

📘 Based on Indian Standard IS 1893 (Part 1): 2016 & 2025
📐 Covers concepts required for seismic analysis of buildings

👉 Watch till the end to clearly understand why the seismic demand in IS 1893:2025 is more realistic than 2016.
