ABSTRACT
A huge part of building heritage in Slovenia was built in the period before 1895, when the most intense earthquake hit Ljubljana region. Till then building practice was based upon the experience, but from then on first seismic code was prepared to prescribe measures for adequate seismic safety. It was an ordinance for earthquake resistant construction of buildings, a very prescriptive-type code based mainly upon the observation, how a structure suffers damage during earthquake. From that first, most prescriptive type of seismic code the vital professional knowledge has been incorporated into the following codes. Not really earlier than the destroying earthquakes hit Friuli and Montenegro in 1976 and 1979 the design-engineers became more aware of destructive potential of earthquakes. Noticeably higher seismic resistance level of building stock was enabled by the application of last national code from 1981, which is now being replaced by Eurocode 8.
