Study on the Structural Floor Design of High-Rise Buildings
There is a high-rise building whose main structure is framework - core tube. In order to meet the requirements for architectural features, the distance between the outer frame and the exterior wall of core tube is relatively small, therefore the floor structure program adopts a thick plate and wide flat beam floor system, and part floors of the upper structure adopt a thick plate and dark beam system. As wide flat beams (dark beams) have a small height and cannot form effective support for the floor, special analysis has been made on floors from the security point of view without considering the role of wide flat beams (dark beams). The floor system of this high-rise building has been analyzed and discussed with regard to bearing capacity, deformation, comfort and other aspects.
