Influences of Beam Type Strengthened Storey on Horizontal Displacement in Super High-Rise Structure

Abstract

The mechanics principle of setting strengthened storey to control the horizontal displacement in super high-rise structure was analyzed, several super high-rise frame tube structure models were established and the maximum peak displacement as well as storey displacement of the structure under the horizontal earthquake load were analyzed via the finite element program; Utilizing controlling structural horizontal displacement as a judge objective, the appropriate setting number of strengthened storey and optimization location were obtained; eventually, the methods on improving the lateral stiffness via setting beam type strengthened storey in super high-rise frame tube structure were put forward. The obtained conclusions are capable to be a reference for designers.
