| Abstract |
The history of tall buildings begins in 1853with the development of elevators. After the Industrial Revolution of the 18th century, the
development of high-rise buildings will be carried out in earnest as a means to efficiently use the limited land of cities. The development,
which began around Chicago, extended over a long period of time to Asia, maximizing the high competition. However, in the 2000s, not
only was it high due to the development of construction and digital technology, but it also became competitive in eco-friendly elements and
unstructured forms. High-rise building plans that have gained elemental and morphological diversity are completed by the interrelationships of
various plans. Among them, it is important that the core plan has a reasonable approach from the initial planning stage as the basis for the
vertical copper plan linking vertically-intensive functions. The cores should be designed to be clear and adequately responsive to changes in
the shape of the building. This study aims to provide designers with a reasonable understanding of core planning by identifying core characteristics of irregular
high-rise. In particular, we want to analyze the shape of the ground layer core and the relationship between the area and components of the
ground layer core. The analysis results are as follows, classified according to the type or use of the building. Of the atypical forms
composed of double bending, the TAPER-Curve and TWIST forms are the most distributed, and the plane and core shapes of the ground
floor are the most commonly used. Based on the analysis of the validity of the ground floor cores by shape of the cores, the most
commonly used forms for core shapes in the planning of the atypical high-rise are square, circular and Oval, and the most efficient oval
cores and relatively inefficient ones when planned. |
