Low strength non engineered masonry buildings are quite unsafe in case of Earthquake or Cyclone and may lead to collapse resulting in loss of life of the occupants. These buildings may not have proper foundations, load transferring members and roof. There are many such buildings in Asia, especially in South Asian countries. The typologies, construction materials, construction system, envelopes of these buildings are quite different from each other. These buildings can be retrofitted with local construction materials using local workmanship at an affordable prices.This book talks about the safe construction practices in various vulnerable zones and construction techniques to retrofit various types of low strength masonry non engineered buildings with illustrations. The buildings covered are constructed with mud, stone, timber/bamboo, low strength building blocks, fired clay bricks, etc. One practical example of strengthening an 60 year old masonry building is also given in this book.
