| Research Abstract |
The aim of this research is to establish a reasonable method to evaluate remaining performance of structural steel in steel buildings after yielding or crack initiation due to earthquakes. In this study, tensile load was applied to round steel bar specimens and then the specimens were investigated by X-ray CT to measure void volume or crack length inside the specimens. The observation results approximately agreed with the finite element analysis showing the possibility to evaluate remaining performance with these analysis and observation.
