ABSTRACT:

A new structural arrangement style of high-rise tubular 3D par king structure is presented, which is to set hoop stories like bamboo knots at the proper levels along the height, and the optimal arrangement principle of hoop stories is analyzed. The static properties and stability of the structures with different arrangement schemes of hoop stories are compared. Results indicate that, the lateral stiffness of the structure with hoop stories set according to the equal stability and equal drift principle is remarkably improved; the storey drift becomes more uniform, which benefits the stable operation of hoisting machines; also, the sudden change of the internal forces of columns is relatively moderate and the structural overturning resistance is enhanced. Finally, the parametric analyses on static properties and stability of the structures with optimal arrangement of hoop stories are studied in detail.、
