Abstract


The determination of strength reduction factor of MDOF structures is essential to study soil structure interaction. International codes ATC, FEMA, UBC, IBC and Current codes {IS1893(PART1&2)} etc emphasize the need for evaluating SSI if the structure is resting on other than rocky or rock like material having SPT-N value less than 50. The current SRF in seismic codes is based on fixed base structure. Subsoil flexibility is to be investigated for accurate evaluation of SRF. However SRF were not well defined by various authors and contribute in different way without uniformity among various researchers. It is also noticed that researchers are sticking on their own definitions to verify their results in the academic world. The typical values given in codes of developed countries cannot be applied to developing countries irrespective of ground motion, site conditions, ductility demand etc. The various codes provide values for strength reduction factor depending on type of structure, namely moment resisting frames with or without shear wall/ load bearing, steel, rcc/masonry structure. In this paper, the definitions of different authors and codal provisions of various countries like USA, Romania, Japan, Newziland, Switzerland, India and European codes are compared in order to interpret SRF. These will allow structural and geotechnical engineers to quickly and accurately establish the actual SRF for multistorieyed building structures due to SSI. The definition part of the article had already been published in an international journal.
