&nbsp; &nbsp; &nbsp; &nbsp; In Japan, many&nbsp;tests have been conducted to investigate high-strength steel reinforced concrete members. This is due to the country&#39;s dense population and&nbsp;location in a region of high seismicity.&nbsp;Most publications about these tests were written only in Japanese. With increasing interest in the implementation of high-strength steel reinforcement in the United States,&nbsp;there is an urgent need to translate key parameters and findings&nbsp;from these tests to English. This is the purpose of this dataset: to translate key information about specimens, their performance, and the authors&#39; observations from Japanese to English. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The data presented herein were gathered exclusively&nbsp;from&nbsp;papers published in Japanese.&nbsp;The units were converted&nbsp;from metric to U.S. customary.&nbsp;In order to facilitate comparison with other data, parameters used to organized the data were taken from the ACI 369 Rectangular Column Database. These parameters are described below.
