The Analysis of Hysteretic Behavior of Concrete Filled Double Skin Steel Tubular after Exposure to Fire

Abstract:

In recent years,frequent fires and earthquake make the buildings damage badly,and it causes huge economic loss. Concrete filled double skin steel tubular (Hereinafter referred to as CFDST) as a new member of structure,its mechanical properties are similar to concrete filled steel tubular,at the same time has better fire performance and seismic capacity. Based on this background,the paper expounds study the mechanical performance of CFDST is very important,the hysteretic behavior is the main mechanical indexes of the seismic performance of CFDST after exposure to fire. The study of it will fill the new component in the blank of seismic performance research.
