In this paper, a multi-tower structure is analyzed as complex structure with program MTBSA special for muti-tower and TBSA special for singal-tower respectively. Comparasion is carried out to draw some conclusions subsequently. And then the trans-truss as transfer storeys is analyzed in computing. In this way, this paper presents design reference for the practical application of transtruss in complex structures.
Keywords:  multi-tower structure; transfer storey; trans-truss; megastructure
