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.

이 연구에서는 평면, 입면 및 구조적 특성이 다양한 철근 콘크리트 고층 아파트 건물의 고유주기를 예측할 수 있는 새로운 식을 제안하였다. 제안식은 벽체의 진동이론과 지진시 계측된 건물들의 고유주기로부터 개발 되었으며, 평면에서 다양한 방향으로 설계된 전단벽의 구조적 특성을 적절히 반영할 수 있다. 제안식의 검증을 위해 신축 중인 국내 아파트 건물 10개동의 고유주기를 측정하였으며, 측정된 고유주기는 제안식 및 KBC 2009, ASCE 7-10과 같은 기준식들과 비교 하였다. 비교 결과, 제안식은 기준식에 비해 최근의 철근콘크리트 전단벽 건물 특성을 합리적으로 반영함으로써 고유주기를 보다 정확하게 예측하는 것으로 나타났다.
