Abstract
A new formula is proposed for the fundamental period of high-rise residential concrete shear-wall (SW) buildings. This formula, developed on the basis of dynamics with the recorded fundamental period during the recent earthquakes, can consider the wall stiffness with respect to any direction. To verify the proposed formula, the fundamental period of 10 sample buildings, measured during construction, is compared with the predicted fundamental period. Furthermore, the empirical formulas presented in the building codes KBC 2009 and ASCE 7-10, are also compared with the proposed formula to show a rationality of the proposed formula. The comparison results show that the proposed formula not only can rationally consider the characteristics of each shear-wall, but that it also accurately predicts the fundamental period of the buildings.
