Experimental studies on CES structural system have been carried out in the past about ten years. To date, seismic behavior of CES columns was investigated to reveal the synergistic interaction between FRC and encased steels, and to evaluate the stiffness, flexural strength and hysteresis characteristics, in which the main test parameters were the section shape of encased steels, the type and content of fibers used for FRC and the applied axial load levels. CES beam-column joints were also tested to investigate the seismic behavior of both interior and exterior joints. This paper summarizes the test results and discusses how to evaluate the structural characteristics to be required in the structural design practice such as the cracking, yield and ultimate strengths and the hysteresis characteristics of CES columns and beam-column joints. The test results show that the CES columns and beam-column joints have excellent seismic performance with a stable spindle-shape hysteresis characteristic, which are better than those of SRC columns and beam-column joints. It is revealed based on the test results that the AIJ design formulas for SRC structures can applied for evaluating the ultimate strengths of CES columns and beam-column joints. Hysteresis models for CES columns are also proposed and verified their validity for the practical use through comparing them with the test results.
