Abstract: The Yongsan "Cloud" project- Block R4a is located at Yongsan International Business District (IBD). Block R4a consists of two luxury residential towers with 243m and 263m height. A habitable 7-storey "Cloud" structure is proposed to wrap around both towers from 148m to183m. The "Cloud" linkage is a geometrically complex feature with lots of void inside, and significant cantilever spans-up to 32m. The structural system for the "Cloud" is rather complicated on both a local level in terms of its own stability as well as on a global level in terms of its participation in the overall tower behaviour under the horizontal loads such as wind and seismic. The core part of this project is how to deal with the relationship between the towers and the "Cloud" of its stiffness and connection, and how to design the "Cloud". It is going to illustrate the comparison analysis and study of the "Cloud" design ,as well as the two base towers' design.
