Sažetak
Empirical formulas for estimating the fundamental period provided by building codes are generally expressed as a function of building height, material (steel, reinforced concrete (RC)) and building type (frame or shear wall (SW)). Although these empirical equations are widely used in practice, it has been indicated that they can be improved. In order to evaluate the dynamic properties of RC SW buildings, a parametric study on 230 different RC building models with shear walls was carried out by varying the following parameters: building height, number of bays and the ratio of shear walls area to floor area. The periods obtained from eigenvalue analysis were compared with the period obtained using building codes. Direction based expressions are proposed for predicting the elastic period of regular RC SW structures and are obtained by performing non-linear regression analysis on the database using genetic algorithms.
