Abstract
Rad obrađuje potresni odziv plitko temeljenih konstrukcija na mekim tlima. Istraživanje u okviru rada je pokrenuto uz glavnu pretpostavku da europski normirani spektri odziva za meka tla nisu dobro definirani te da ne uključuju učinke međudjelovanja tla i konstrukcije. S ciljem definiranja poboljšanog spektra odziva kao osnovnog alata za proračun sigurnih i potresno otpornih konstrukcija, izrađene su i funkcije impedancije i prijenosne funkcije koje omogućuju uključivanje učinaka međudjelovanja tla i konstrukcija u proračunima primjenom metode spektara odziva. Oslonac studiji daju rezultati eksperimentalnih istraživanja provedenih na potresnom stolu na Sveučilištu u Bristolu te u geotehničkoj centrifugi na institutu IFSTTAR. Numerički modeli korišteni za provedbu parametarske studije su uspješno kalibrirani s obzirom na rezultate spomenutih eksperimentalnih istraživanja. U radu je dan prijedlog primjene funkcija impedancije, nastalih u okviru ovog rada, u klasičnim računalnim programima koji primjenu nalaze u znanosti i praksi. Osim toga, dan je prijedlog za primjenu funkcija impedancije u okviru N2 metode.

This thesis deals with seismic response of shallow founded structures on soft soils. Research within the thesis is initiated with the main assumption that the European code-based response spectra for soft soils are ill-defined and that they do not include soil-structure interaction effects. With the aim to provide improved response spectrum, as a key engineering tool for design of earthquake resistant structures, both impedance and transfer functions were developed. Those functions enable incorporation of both soil compliance and its capability that dissipates earthquake energy. Parametric study was conducted using numerical models calibrated with regards to experimental results obtained both from testing performed in enhanced gravitational field using geotechnical centrifuge at the IFSTTAR institute and on shaking table of the University of Bristol at 1g. Numerical modelling, and thus parametric study, was governed using equivalent linear method. The last chapter of the work provides proposed methodology for including the developed functions into classical program packages mostly used by engineering practice and academia for structural analysis and design. Also, proposal for application of impedance functions within the framweork of N2 method is provided.
