Earthquake loads are covered in which part of IS 875?
- APart III
- BPart IV
- CPart V
- DNone of the aboveCorrect
Solution
Concept
Code provisions governing earthquake design loads
Formula
IS 1893: Criteria for Earthquake Resistant Design
Step-by-step solution
1. The IS 875 standard series is divided into 5 specific parts: Part 1 Dead Loads, Part 2 Imposed Loads, Part 3 Wind Loads, Part 4 Snow Loads, and Part 5 Special Loads. 2. Earthquake loads require complex dynamic and seismic considerations and are separated into IS 1893. 3. Because no part of IS 875 covers seismic loads, option D (None of the above) is correct. Answer: D
Explanation
Earthquake loads are excluded from the IS 875 code series. Instead, seismic design loads and criteria are exclusively codified in IS 1893. Therefore, none of the parts of IS 875 cover earthquake loads.
Why the other options are wrong
A) Part III covers Wind Loads. B) Part IV covers Snow Loads. C) Part V covers Special Loads and combinations, excluding earthquakes.
Shortcut
IS 875 does not cover earthquakes; IS 1893 governs all seismic loads.
Common mistake
Assuming IS 875 Part V covers earthquakes because it includes special loads.
Correct answer: D) None of the above
