Civil Engineering/earthquake design


Sir,when we design buildings to resist earthquakes,do we design them to undergo deformations in elastic range or inelastic range.Please explain

Dear deshmukh

1- Seismic design is based on collapse prevention and life safety under maximum credible earthquake . Then inelastic behavior under MCE or DBE (design basis earthquakes) level of earthquake. almost all codes accept this principle.

2- Seismic design is based also on serviceability of building after a frequent earthquake which may occur at least one time in the life time of the buildings. Some codes accept and follow this level explicitly but almost all accept it as  implicit criteria. In this level no inelastic behavior is expected from the building.
