Abstract
슬래브의 강성을 고려한 고유진동수를 간단한 수 계산으로 산정하기 위하여 기존의 근사 해석 방법에 슬래브 강성과 질량을 대입하여 전체 구조시스템의 고유진동수에 대한 기존의 근사해석방법과 비교하여 슬래브의 효과에 따른 고유진동수의 변화를 분석하였다. A simple hand method is presented for calculation of the natural frequencies of RC buildings by frameworks, coupled shear wall, shear walls and cores. The method is for structures that have uniform properties through their height, and that are symmetrical in plan so that they do not twist. Also, Effective stiffness for the equivalent beam in beam-slab buildings is used for account for slab's contribution to the increase of stiffness of structures. Lateral vibration is characterised by the three types of deformation: the full-height local' bending of the individual columns/wall sections/shear walls/cores, the full~height 'global' bending of the frameworks/coupled shear walls, and the shear deformation of the frameworks/coupled shear walls. Based on the stiffnesses associated with these three types of deformation, a closed formula Is derived for calculation of the lateral frequencies.
