✦ Synopsis

In the present paper, experimental results of concrete-filled steel box columns under cyclic and dynamic loading are reported. In the experimental work of cyclic tests, the effects of main parameters, such as the width-thickness ratio, number of loading cycles, length of filled-in concrete and a diaphragm above the filled-in concrete on the column behavior, were studied. To investigate the dynamic behavior of concrete-filled steel box columns, three specimens with different natural periods were tested using the pseudodynamic test method. For comparison, a hollow steel column specimen with the same dimension was also tested. Test results showed that concrete-filled steel box columns can be effectively used as bridge substructures to withstand severe earthquakes.

The primary purpose of the investigation conducted by the authors was to provide designers with some basis to estimate dynamic creep from static creep information. The authors do not disagree with the discussors' definitions of cyclic creep and fatigue as portrayed in their Ref. I. From the work co
