Abstract

For the earthquake design of RC structures, period of vibration is not known immediately, and because of that the simplified expressions are given in the construction rules, which usually link the base period with the height of the construction. The aim of this paper is to verify these empirical expressions, which are given by different authors and Eurocode 8 and to conclude whether the expressions are good enough as a starting assumption for the design of earthquake resistant buildings. Most attention will be devoted to the RC frame structures. When modeling, besides the general requirements on the structures, typical requirements for particular types of structural systems will be applied. Results of the models and empirical expressions will be compared and the conclusion about applicability of the expressions will be drawn.
