Sažetak
Expressions for estimating the fundamental period provided by Building Codes are generally given as a function of building height, building type (frame or shear wall), etc. Although these equations are widely used in practice, it has been indicated that they can be improved. A difference in the period of an RC frame structure is also noticed depending on whether the longitudinal or transverse direction of the structure is considered. We propose new expressions for fundamental periods of regular RC frames which take into account the direction of the structure considered, by performing nonlinear regression analysis using genetic algorithms on 600 different models of RC framed structures.
