    Abstract
    By the increase of strong motion data, soils response has become inelastic dynamic response. Based on the load-deformation relation of soils that are non linear, then soils response will be a non linear analysis of inelastic. One of the methods that describe strain-stress relation of soils was Ramberg Osgood Hysteretic (1943). The condition of soil layers will different between free field and building mass effect. A mass of building will have an impact on increasing ground stiffness so that dynamic response would come out different. These differences need to be researched to provide information how the influence of the building on the dynamic response of ground below. The evaluation of inelastic response was done by taking the theoretical standpoint of earlier references and investigating the two soil profile in Yogyakarta. Both of them is Mataram City Hotel and Academic Hospital Of Universitas Islam Indonesia. In addition, there are also data structures as input of the load mass building that will affect the soil layers. The analysis was done with variation of soil deposits and earthquake records (Bucharest, Elcentro, Duzce Turki Elnashai, Manjil, Duzce Turki, and Loma Prieta), then these analysis is presented by using β-Newmark direct integration methods.The formulations are adopted to MATLAB R2010a. The results of analysis have shown that inelastic response will be very significant only in the displacement, shear strain and shear stress. A mass of building will decreases the response of displacement and shear strain of soil layers. In addition, it is also increase the response of shear stress. The velocity and acceleration response shows significant decrease on the first soils profile for each earthquake. It is different for second soils profile that shows significant decrease only on high frequency of earthquake. Meanwhile the spectral acceleration shows that the natural periods of PGA will decrease when the soils was affected by building mass. It means that the frequency of earthquake will be increase
