Causes of Earthquake Damage in Buildings

  1. Heavy dead weight and very stiff buildings, attracting large seismic inertia forces.
  2. Very low tensile and shear strength, particularly with poor mortars.
  3. Brittle behaviour in tension as well as compression.
  4. Weak connection between wall and wall & roof and wall.
  5. Stress concentration at corners of doors and windows.
  6. Overall un symmetry in plan and elevation of the building
  7. Un symmetry due to imbalance in the sizes and positions of openings in the wall.
  8. Defects in construction, such as use of sub standard materials, unfilled joints between bricks.
