Earthquake resistant home

Construction Guide Logo

In areas prone to frequent earthquakes, houses should be designed keeping in view the earthquake forces likely to develop. Following general rules should be adopted in the construction of earthquake resistant home.

  1. The foundation of the house should not rest on the loose soils but on solid rigid base. Loose soils settle easily during an earthquake and cause damage to the house.
  2. Different elements of the house should be properly tied with each other, such as the whole house behaves as a single unit.
  3. Unnecessary projections should be avoided and balconies, canopies etc. should be firmly tied with the main structure.
  4. As far as possible, suspended ceiling should be avoided. Thickness of ceiling plaster should not be more than 6mm.
  5. Old and new parts of the structure should be joined with the help of cripple sections. The structure will fracture or cripple only at these sections during earthquake.
  6. In order to avoid collision between adjacent structures, gaps of suitable widths should be provided at the rate of 15mm to 30mm per storey of the house.
  7. Simple rectangular plans should be preferred. Length of the house should not exceed three times the width of the house.
  8. Structure should be made as light as possible.
  9. Structural and non-structural parts of the structure should be connected in such a way that deformation of structural parts cause minimum damage to non-structural parts.
