In practice, however, earthquakes generate stronger ground motion than Level 1 but not exceeding Level 2 can occur in service life of a structure. In current seismic design, consideration was not given directly to changes in activities and risks to the seismic motion through time and the importance of adopting effective methods of repair and reinforcement. These factors can not be implemented fully into account by simply checking the elastic limit or reparability limits or structural collapse of a Level 1 or 2 earthquake motion forces based on current seismic design | FLUID DYNAMICS COMPUTATIONAL MODELING AND APPLICATIONS Edited by L.
