Abstract:
Considering the very large number of circular concrete columns used to support buildings and bridges and the critical importance of ensuring that the shear strength of these members is sufficient to survive a possible earthquake, relatively few studies have been conducted on the shear strength of circular reinforced concrete columns. This paper summarizes the results of three experimental investigations in which a total of I.5 large circular specimens were tested in shear. The paper also explains how analytical models based on the modified compression field theory can be used to predict the shear response of circular reinforced concrete columns.
