Earthquake Resistant Construction MCQ with answer and solution

Concept

Scope and application of IS 13828 standard

Formula

IS 13828: Low Strength Masonry Buildings

Step-by-step solution

1. Low-strength masonry includes adobe, unburnt bricks, stone masonry in mud mortar, and earthen buildings common in rural construction. 2. IS 13828 provides specific guidance to prevent brittle collapse of these low-strength materials during earthquakes. 3. Multi-storey RCC and prestressed structures are covered by IS 13920 and IS 1343 respectively. 4. Thus, IS 13828 applies directly to low-strength masonry and earthen buildings. Answer: B

Explanation

IS 13828 is titled Improving Earthquake Resistance of Low Strength Masonry Buildings - Guidelines. It is explicitly formulated to provide retrofitting and seismic strengthening guidelines for earthen, adobe, and low-strength masonry constructions.

Why the other options are wrong

A) RCC multi-storey buildings are governed by IS 13920 for ductile detailing. C) Prestressed concrete structures are governed by IS 1343. D) Industrial steel sheds are covered under IS 800.

Shortcut

IS 13828 = Low-strength masonry and earthen/mud mortar buildings.

Common mistake

Assuming IS 13828 applies to RCC buildings, which are governed by IS 13920.
