The purpose of this study is to find out the expression style of space in Rietveld's early works in comparison with Mondrian's paintings. Through investigating the development of their works and analyzing the composition and disposition type of elements such as point, line, plane, color in the selected works, we can draw the following conclusions. .First, Rietveld pursues the dissolution of traditional volume and the de-composition of elements as Mondrian does. Second, the painterly property of plane is emphasized by the projection of separately floating elements on the picture plane. Third, the separating the layer of lines from the layer of planes and the re-combination of these two layers present the superimpositional image of three-dimensional objects. This leads into new conception of architectural space and develops the transparency and the extension of plan in modem architecture.

초고층구조물의 경우 중저층 구조물과 다르게 설계시 중력하중과 풍하중의 크기가 매우 크므로 이를 제어하는 구조물의 코어에 강성이 큰 전단벽을 설치하고 최상층에 아웃리거나 벨트트러스를 설치하는 방법을 많이 적용한다. 그리고 홍콩의 IFC와 같이 초대형기둥과 아웃리거를 설치하여 횡하중에 저항하는 구조시스템도 제시되고 있다. 이러한 초고층구조물에서 연쇄붕괴가 발생할 경우 세계무역센터의 붕괴에서 나타나듯이 상상을 초월하는 피해를 초래할 수 있다. 따라서 본 연구에서는 이러한 초고층 구조시스템의 연쇄붕괴저항능력을 Pushdown해석을 이용하여 평가하였다.

Serpentine belt drive system offers the advantages of light weigh, low cost, quientness, and efficiency. Since these belts are typically longer than conventional belts, a tensioner component is added to maintain acceptable belt tension levels and make no slippage between pulleys and belts. This paper addresses the modeling and analysis of the automotive belt drive systems and also addresses the predicton of slippage on rotational modes. Vibration characteristics are determined from the eigenvalue problem governing the free response. Under certain engine operating conditions, the dynamic tension fluctuations may be sufficient to cause the belt to slip on particular accessory pulleys, It is found that this slippage can be reduced by adding the tensioner component from the analysis of belt tension and belt compression.
