RATIONAL STIFFNESS OF OUTRIGGERS IN HIGH RISE STRUCTURE WITH STRENGTHENED STORIES
Based on theoretical analysis results of simplified planar structures, this paper studied the influence factors to roof displacement and internal force of a spatial structure subjected to uniform load and load with an inverted triangular distribution. The factors obtained from simplified theoretical analysis including location and number of strengthened stories and stiffness ratio of outriggers to core tube and side columns to core tube. Using numerical calculation, this paper analyzed the stress characteristic of this kind of structure and proposed a stiffness ratio limit of outriggers to core tube. Conclusions can serve for a reference for actual design.
