Seismic design philosophy for buildings


The seismic design philosophy may be explained as follows:

  1. Under minor but frequent shaking, the main members of the building that carry vertical and horizontal forces should not be damaged, however building parts that do not carry load may sustain repairable damage.
  2. Under moderate but occasional shaking, the main members may sustain repairable damage, while the other parts of the building may be damaged such that they may even have to be replaced after the earthquake.
  3. Under strong but are shaking, the main members may sustain severe (even irreparable) damage, but the building should not collapse.
