Abstract：Based on a 518-meter-high super high-rise building which is under construction, the paper made a summary on the practical problems during the application of solid-web structural steel in construction. With consideration of the mechanical performance of the mega column in the mega frame of the project, adjustment was done on the internal structural steel layout of the mega column: solid-web was used in the joint zone, and open-web in non-joint zone. Finite element analysis was done on the joint of the mega column. The result showed that with the transmission of the internal force in the joint zone, the force in the non-joint zone was diffused homogenized and no obvious internal force was transmitted between structural steel of different types. So it is feasible to use open-web structural steel in non-joint zone. On the experience gathered in the construction of SRC mega column of super high-rise buildings, the authors believe that the mixed-type steel layout can not only meet the demands on structural capacity but also improve the feasibility of construction and reduce the structural cost, as well as serve as a reference to the structural design of similar super high-rise buildings.

Keywords: Mega frame structure; open-web structural steel; solid-web structural steel; SRC mega column; infinite element analysis
