The sky-lobby is set up on the 21st floor of the super high-rise building of Shenzhen Aerospace Industry Technology Research Institute.In order to realize the creation of hollowing out and lightness,the structure adopts the floor of the sky-lobby suspended by the steel suspender with the vertical style of the glass curtain wall.The stability of through-story columns and through-story walls was studied by elastic buckling analysis.The normal section bearing capacity of the column was checked by PMM yield ball.The elastic-plastic time history analysis method was used to review the bearing capacity of the through-story wall.The walking excitation vibration response analysis method was used to analyze the comfort of the suspended floor in the sky-lobby.The bearing capacity performance of the suspended floor was evaluated by stress analysis method.The performance-based design method was used to check the bearing capacity of the steel suspender of the suspended sky-lobby.The elastic-plastic time history analysis method was used to check the bearing capacity of the hanging beam.The results show that the stability of the through-story column and the through-story wall meets the requirements of the specification;the natural vibration frequency and vertical acceleration of the suspended floor meet the comfort requirements;the selection of steel suspender is reasonable and reliable;the bearing capacity of through-story columns,through-story walls,suspended floors,steel suspender and hanging beams can meet the requirements of the established seismic performance objectives.The structural scheme adopted not only better realizes the architectural creativity,but also the structural design of the sky-lobby is safe,reliable,reasonable and feasible.
