Efficient Vibration Analysis of Floors in A Shear Wall Building Structure

벽식구조물 바닥의 효율적인 진동해석

Recently, many high-rise apartment buildings using the box system composed of only reinforced connote walls and slabs, have been constructed In residential buildings such as apartments, vibrations occur from various sources and these vibrations transfer to neighboring residential units through walls and slabs. It is necessary to use a refined finite element model for an accurate vibration analysis of shear wall building structures. But it would take significant amount of computational time and memory if the entire building structure were subdivided into a finer mesh. Therefore an efficient analytical method, which has only translational DOFs perpendicular to walls or slabs by the matrix condensation technique, is proposed in this study to obtain accurate results in significantly reduced computational time.
