Nowadays , specified that the designed structures according to existent design code , sufferer strong damages in high earthquake. Nontheless the base of most seismic design code is according to elastic analysis and use of static force equal to earthquake. in design seismic forces have approximate nature and the seismic design forces that suggested with the seismic codes are smaller than the froces imposed to the structures in earthquake. the employed forces will earthquake is depending on the elastic and plastic behavior of the structures.
