The paper presents a seismic analysis of a 2D reinforced concrete (RC) frame founded on piles. The soil-pile interaction is represented by the so-called p-y curves. At the base, the piles may be both fixed or elastically supported. P-y curves are determined according to Rees, Cox and Matlock model for sand. Using SAP 2000, p-y curves are applied on both sides of the pile, as the link elements. Link elements are assumed as a multi-linear plastic type, i.e. as hysteresis envelopes according to the Takeda model. The linear part of the link element corresponds to initial stiffness of the p-y curve. Curves are exposed to compression only and to almost negligible tension. In the analysis of seismic action, the curve coefficients for a repeated, i.e. cyclic load were assumed. In such a way, numerical model asymptotically simulates the real actions and seismic response of structures in dynamic interaction of the pile-structure-soil system. This model offers many options for further development... and study of seismic performance.
