Abstract

The concrete-filled double-skin steel tubular (CFDST) structure can effectively prevent structural damage caused by high temperature, high pressure, and vibration, and ensure the integrity of the plant throughout its service life. However, in the engineering application of CFDST to reactor pressure vessels, the seismic performance of CFDST columns characterized by large structural scale, high hollow ratio, and low steel ratio has not been fully stressed. In this study, a 1/8-scaled specimen was designed for cyclic loading test. The hysteresis curve is analyzed. Then, a refined finite element model is established to study the seismic performance of CFDSTs.
