Modeling of Behavior of Continuous Energy-Dissipative Steel Columns Under Cyclic Loads

LI, Yan-Wen / LI, Guo-qiang / JIANG, Jian / SUN, Fei-Fei

This paper presents analytical and numerical models of cyclic behavior of a novel continuous energy-dissipative column (CEDC) system. It consists of two steel columns connected by replaceable steel strip dampers (RSSDs). The CEDC system is designed to realize the function of energy dissipation, lateral resistance, and mitigating inter-story drift concentration. The formulas to determine the elastic stiffness, yield, and ultimate capacity of the CEDC system are derived based on continuous medium method. A simplified model of hysteretic behavior of the CEDC system is proposed and validated with experimental results.
