A Study on the Application of Outrigger to Super-tall Steel Structures

Based on the numerical computation of real structures, a thorough research on the earthquake response of outrigger braced super tall steel structures is introduced in this paper. In comparison among several different schemes, further research on the influence of the quantity and bending stiffness of outrigger and the exterior belt on the earthquake resistant performance of structures is also presented. In the end this paper put forward a method of selecting the stiffness of outrigger for reference in practice. [
