LDC-H6 Building (The Center) is under construction in Hong Kong, with the height of 300m and 73 structural floors. Having a unique elevation and star-shaped plan without concrete core, it realized the flexible and minimum core area which enabled maximizing office efficiency in the limited floor area. Various analyses are carried out for examining the performances of its starshaped moment frame tube, and compared with a Japanese building which has the similar height and structure. This paper briefly reports on above studies, and discuss on the structural design between Hong Kong and Japan.
