Abstract
In this research the governing relationships of the behavior of seismic isolated shear frame structures are presented and algorithm solution was written for multi degrees of freedom “MDOF”model, considering the masses lumping at the center of diaphragm in each story and taking into consideration the bilinear model of the isolators. To verify the algorithm a computer program was written using “Visual Basic” and a numerical example was solved. The results are compared with those obtained by using “SAP 2000” Program.
