Residential high-rise buildings, such as apartments and condominiums, were introduced to provide multiple residential spaces in urban and suburban areas for their economic advantage and convenience for commuting to urban business districts. Old-fashioned apartments were basically stacked rectangular box buildings. The typical floor framing system was a concrete flat slab with beams, supported on columns and bearing walls conveniently hidden in the partitions between rooms and apartment units. It was very practical and economical since all every apartment units were vertically stacked and had the same layout, thus allowing simple vertical risers for MEP services. Recently, prospective tenants have started demanding the ability to customize their interior designs to accommodate varying family sizes and lifestyles. More functional and practical layouts were preferred to old standardized apartment modules. This space planning conflicted with the traditional column and wall layouts, spurring demand for a new flexible structural system in order to satisfy tailored requests of tenants. A concrete flat plate floor surrounding a central core wall system became appealing because this system provides flexibility to tenants to modify the interior space to suit their own lifestyles. The tallest concrete tower in Korea, The # Star City project, has adopted this long-span structural system as described above.
