Abstract:Combined with the structural design of a complex service building, the difference in regularity of building configuration and structural assembly  between China and foreign countries in seismic design was analyzed. The office building has an irregular arrangement in vertical, and diverse transfer structures were analyzed with MIDAS software. The results show that transfer truss, vierendeel truss and transfer beam are also adapted to the structure, and the deformation, steel consumption are increased in turn. The design problems about the joints of different steel tube were introduced.

Keywords: seismic design; transfer structure; joints
