Towers Busan – World Business Center Korea
Dates: 2006-11
Design: UNStudio
World Business Centre Busan, 2011, UNStudio
This Korean skyscrapers project was a competition entry, for which it received second prize in the last phase. It will therefore not be built in it’s current form or location.
date 16.10.2006
Name of Project: Rolling Curves – World Business Center, Busan
Project: one 100-storey highrise and two 50-storey highrise + masterplan, Busan
Description: International Invited Competition for The World Business Center, Busan, Korea
World Business Centre Busan, 2011, UNStudio
(WBC Busan)
Centum City’s Block 23 & 24 in Haeundae-gu, Busan City, Korea
Function:
The Competition for the WBC, focuses on two blocks within Centum City, to establish an integrated design plan of super high-rise structures in this area. It aims to develop Busan as a hub city of the Northeast region and to generate the maximum synergy in connection with development and extension of other complexes within Centum City. The objective of the project is to achieve the tallest height in Asia – by creating a landmark tower with mixed-use functions.

Structural System
The two towers are proposed in reinforced concrete with outriggers. This proposal is an economic, sound and fitting structural solution for a tower of this use, size and proportion. Within this structural system the core carries lateral shear loads and the outriggers mobilise the columns to carry vertical bending forces, limiting lateral movements and accelerations at the top of the building.

The lower floors of the tower are all of standard floor dimension and repetitive floor to floor to allow the use of flying formwork.
The formal transition zone in which the cruciform (4 plan extensions) plan configuration adjusts to a triform (3 plan extensions) occurs within a defined centre portion of the building. Within this zone are two sets of outriggers at the top and bottom of the transfer structure.
The transfer structure is formed by a triangulated cylindrical warren truss making the transfer between the six upper columns and the eight lower columns. Outriggers are required at the top and bottom of these transfer columns. The outriggers are storey deep trusses between the core and outer columns. The outriggers mobilise the columns in tension and compression to limit the lateral deflections and more importantly the accelerations at the top of the building as described above. Outriggers are required at the top of the building as well.

There are several inclined columns in the transfer zone. There are 12 columns making the transition from 8 to 6. That is each of the 6 upper columns splits into 2 creating 12.
These then rejoin such that 4 of the lower columns receive 2 raked transfer columns from above and are tied laterally by the inclined geometry of the raking columns. The remaining 4 lower columns receive only one raking column and there is a resultant thrust. This however is tied laterally to the adjacent column in the pair and resolved back into the curved warren truss system.

All of the upper floors above the transfer zone are of standard dimension allowing repetitive formwork.
