Abstract
This paper presents an experimental study of the behavior of 200MPa UHSC columns confined by rectangular ties subjected to concentric compression. Twelve large scale columns (220*220*1000mm) were tested in order to recognize the effects of the main variables such as the concrete compressive strengths, tie configurations, amount of the transverse reinforcement. The behavior of UHSC columns are characterized by sudden spalling of concrete cover and extremely brittle behavior, unless the columns are confined with transverse reinforcement that can provide sufficient high lateral confinement pressure. Therefore, more confinement is required in a column with higher concrete strength than in a column with lower concrete strength to achieve the same amount of strength enhancement in both columns.
