Abstract: Software building in Suzhou Science and Technology Town belongs to complex shape and especially irregular tall building structure. Firstly, the architectural and structural design features, as well as the measures taken of the software building were determined. Secondly, based on finite element analysis, the computational analysis of the slant column and frame, structural details of design, and the overturning-resistant design of the overall structure were descript in detail. Meanwhile, some effective measures on controlling the settlement differences between the main building and pure basement were presented. Finally, both the inelastic Pushover analysis and the elastic time history analysis of the seismic response of the overall structure were done. The results show that the structure can meet the code’s requirements for complex tall buildings, and can ensure the structure safety.

Keywords: tall building; especially irregular; slant column and frame; overturning-resistant design; seismic design
