ABSTRACT

ABSTRACT: The podium of CNOOC Shenzhen Building is a four-storey large-span structure situated between two super high-rise towers. To fulfill the requirements of the local municipal planning and architecture functions, a new-type structure was proposed for the podium, named as Steel Reinforced Concrete (SRC) frame-four corner tubes-bidirectional steel truss hybrid structural system. Elasto-plastic time-history analysis for the structure under rare earthquake was carried out using the finite element method. The damage of the four corner tubes focuses on coupling beams. Large-span steel trusses keep non-yielding state. The damage on RC beams and steel beams can dissipate some dynamic energy. Therefore the rationality of the structural arrangement is verified.
