Sažetak
Geotechnical reports, filed in the city archives, are the source of data among which relevant properties for mechanical soil behaviour and site response analyses are recognized and digitised. The properties are digitised in an organized manner into the GIS related software called "Techbase", developed by "MINEsoft", Lakewood, Colorado. The basic element of the database is a boring log containing distributions of soil properties with depth. More than 150 boring logs, located in the western part of Zagreb, are digitised and their coordinates mapped using "Techbase". The aim of this paper is not only to describe the collection of the geotechnical database, but also to present its use for developing techniques for the estimation of soil-related response to earthquakes as well. The process of obtaining the seismic design model and its use in assessing free field ground acceleration are described. As borings usually do not reach deeper than ten meters, the influence of upper ten meters on amplification of maximum ground acceleration is pointed out.
