Sažetak
Seismic design of safe and economically justified structures is a multidisciplinary and challenging task. Due to complexity in modelling and high computational cost, soil is usually modelled using discrete impedance functions. On the other end, many code-based methods for design of earthquake resistant structures introduce the response spectrum (RS). Albeit both impedance and RS functions may govern design of e.g. nuclear facilities or hospital buildings, they seldom recognize stress induced from structure to foundation soil. This paper shows how this stress change the shear wave velocity distribution within foundation soil, a major soil property that steers the selection and shape of them mentioned functions and thus redirect structural design. A study was conducted: on a set of real soil profiles collected by the authors ; for both low and high structural loading and by using different methods for correction of free-field measurements of shear wave velocity within a soil profile to account for the overburden pressure.
