The purpose of this study is systemizing application process of plan determining factors, and their interrelation, through study on characteristic of several factors and interacton to plan decision.
The result of this study, limited over 30 story high-rise office building in Seoul, are as follow.
The plan of high-rise office building have more restraints and considerations than that of general building.
Many factors in each step determine plan from schematic step (building use, building scale, demands of user, selection of site, etc.) to designing step that size and shape of practical is concreted.
①It is classified that plan of office building is mostly inflaenced by leasing-type which can be said intention of design, leasing-type is classified as Building of office owns, mixed leasing building, and clear leasing use building and each characteristic is manifested.
It is manifested that symbolizing characteristic and public identity are important to building of office owns, economic benefits are important to clear leasing use building, and intention to accomodate both appear certainly in mixed leasing building. This trend influence to plan-determining by being reflected in usage of site and shape of building
②Usage of site and shape of building were differentiated as leasing-type. Building of office owns as the usage of site bring into relief of company to offer public space in exterior and robby of building, clear leasing use building turned up space program to secure maximum building area at site.
mixed leasing buildin have to select either public identify nor efficient usage of site. This usage of site influenced directly to shape of plan and condition which shape of plan determine as shape if site appeared.
Also, Building plan was determined by building shape occasionally. This trend appeared in building of office owns mainly, and efficiency and convenience of plan reduced, because vertical zoning was conducted after determining building shape. Because effect of landmark by height is sufficient, it is difficult to find out other aesthetic figure in building shape.
③Influence over practical use of site, shape of building, structure and etc. comes out in practical shape and size are core, standard floorarea, leasing span, floor height, and etc.
This determining factors determin plan by being selected with optimum under condition of each building is.
Core type was selected by design intention Eccentric aore was selected to offer non-obstacle space that is able to increase ratio of rentable area and, center core was selected to circulation of space and equal distribution of moving line in building.
Also, a rectangle-central core was accommodated to compose bisected space in mixed leasing building.
Mostly, stand floor area was determined by site conditions and regulation(building coverage). The length og leasing span was determined by location or size of core, and floor height appeared differently as the grade of intended I.T.
Plan of tall building formed by determing factors must be flexible space to correspond change of user's business, and must be correspond with spatial composition correspnding I.T by technical development.
Delicate design accepting all conditions is inevitable in plan-design of tall building, and spatial composition, only aimed economic benefit, is not desirable.
Determining factors and te reciprocal action is determine shape and size in plan of tall bilding within a country, was investigated on this study. It is not to speak of importance over plan design in tall bilding.
(But it is considered that)
Unfortunately, objectified plan-determining process didn't be concreted, because object of case-study was limited in this study.
It is necessary that we offer research data be able to standards, plan determining factors in tall building design, by objectifying plan-determining process through the research of more tall building, and the wide-ranging establishment and research of plan-determining factors.
