Most large-sized and tall-risen general hospitals of today fairly depend on in-patient wards in designing hospital styles. The core planning for the efficient movements of various people in the words should take into account the sustainable connections between/among the floors, as well as hospital structures and mechanical functions. This study sampled for the study 19 hospital in-patient wards and investigated their flat-core styles.
It was found out that hospital structures are changing from symmetrical styles of triangles, quadrangles and rectangles through bending, configuring, transforming to efficient new styles.
Symmetrically quadrangled flat-styles are made of multi-cores spread with main an sub-cores. In contrast,symmetrically triangled flat-styles place the open place in the middle in order to prevent from its deepening,and widened the depth line through changing the outdoor top point.
Non-symmetrical rectangles minimized the depth value to maintain the recent styles used in the wards,and tended to prefer the transformed styles of quadrangles. The double-corridors easily transshaped from mono corridors reveals the triangled, W-shaped, or Y-shaped figures.
The site area ratio of the cores is 11.95% in average. The number of beds which one elevator covers is 66.51 beds in average, and the size of site area which one elevator covers 216.68m. Most cores on the base floor clustered around the average value, <Smc> with more than 1000 beds shoes 12.83%, <Amc_e> does 12.93%, <Sev> does 14.64%, <Cmc-s> does 14.58%, which says that the core ratio increases according to hospital beds.
