Analysis and Design of the Combined Isolation in High-rise Frame Core Tube Structure near Field Earthquake Zone of High Intensity
摘要
Abstract
For high-rise frame core tube structure in the near high intensity earthquake zone, the design thinking of the combination with the elastic slide bearing (ESB) and rubber isolator bearing is put forward. The story shear, inter-story displacement angle, floor acceleration, bearing stress and seismic energy dissipation corresponding to the traditional seismic and seismic isolation technology calculated by time history analysis method are compared. Research results show that under frequently occurred earthquake action, the floor displacement and acceleration of the combined isolation structure are decreased by 54% and 60%; under rare earthquake, tensile stress and displacement of the bearing are controlled within the specification limits, the hysteresis curves of rubber isolator bearing and ESB are full, as can be seen from the hysteresis curves, the two kinds of bearings at the same time to enter the yield states, is shows that the two kinds of bearing have good collaborative workability in the design of the combined isolation system, and the rationality of the combined isolation design is verified.关键词
