Which IS code guides design and construction for earthquake-resistant buildings including masonry construction in India?
- AIS 456
- BIS 4326Correct
- CIS 1893
- DIS 2911
Solution
Concept
Indian code for earthquake resistant building construction
Formula
IS 4326: Earthquake Resistant Design and Construction of Buildings
Step-by-step solution
1. IS 1893 specifies earthquake loading and seismic force computation. 2. IS 4326 specifically details construction guidelines and structural detailing for earthquake-resistant masonry, timber, and traditional buildings. 3. IS 456 governs plain and reinforced concrete, while IS 2911 governs pile foundations. 4. Hence, IS 4326 is the governing construction code for earthquake-resistant masonry buildings. Answer: B
Explanation
IS 4326 is the Indian Standard code of practice specifically titled Earthquake Resistant Design and Construction of Buildings. It provides comprehensive guidelines for materials, structural configuration, horizontal bands, and vertical reinforcement in masonry buildings.
Why the other options are wrong
A) IS 456 is the code of practice for plain and reinforced concrete. C) IS 1893 is for earthquake loading criteria, not masonry construction detailing. D) IS 2911 is the code of practice for pile foundations.
Shortcut
IS 1893 = Forces and Analysis; IS 4326 = Construction and Detailing for Masonry.
Common mistake
Selecting IS 1893, which calculates design earthquake forces but does not provide masonry construction detailing.
Correct answer: B) IS 4326
