초록

In this study, we proposed the horizontal story shear strength distribution of buildings considering the predominant period characteristics of seismic waves. The horizontal story shear strength distribution was calculated through trial-and-error method based on damage distribution. As the result of study, the damage distribution trend of analysis model according to the predominant period of seismic wave and the fundamental natural period of the building was that as the predominant period of seismic wave increased, the damage concentrated on the lower floors, and as the fundamental natural period of the building increased, the damage concentrated on the top floor. Based on these results, the horizontal shear strength of buildings in which the damage distribution is uniform according to the predominant period of seismic wave and the fundamental natural period of the building was calculated. The calculated horizontal shear strength coefficient distribution showed a tendency to increase the coefficient of top floor and the curvature of coefficient distribution as the predominant period of seismic wave decreased. The optimum yield shear force coefficient distribution formula was calculated by multiple regression analysis of the calculated horizontal shear strength distribution as dependent variables, the predominant period of seismic wave and the fundamental natural period of the building as independent variables. The Damage distribution of analysis models designed with the optimum yield shear force coefficient distribution formula was controlled by the horizontal shear strength corresponding to the predominant period of seismic wave.
