The long Term Credit Bank of Japan H.Q. Building in Tokyo, completed in 1993 fall, is high rise building of 130 meters with T shape form. There is a 20 meter cantilever at the height of 46 meters. There are two glass cubes under each cantilever. Both glass cubes are designed by using Dot Point Glaging System. Those could be designed very light structure by using that system. This paper firstly outlines structural planning, load conditions and structural analysis, then reports tension structural system that support D.P.G. system, same scale experiment, and construction method.
