ESTIMATION OF CONFINING DUCTILITY OF R/C RECTANGULAR COLUMNS

Abstract

The author has proposed the formulas for estimating the confining ductility of R/C square columns. However, these formulas are not applicable to rectangular columns. In this paper, estimation method of the confining ductility of such columns is clarified on the basis of past tests result of wall specimens subjected to compressive force. Also, the required transverse reinforcement for ensuring the adequate ductility is shown.
