By this way, the disadvantages, caused by the independent vibration characteristic of the concrete structures, are reduced furthest, while the load transfer routes are achieved already. In this paper, the temperature load, the form and the distributing of the support system are introduced in detail, global calculation and analysis of the steel structure, design of typical joints are presented too.
