Determination of Buckling Length of Reinforcing Bars Based on Stability Analysis (2000)
AuthorsDhakal, R.P., Maekawa, K.show all
Average compressive stress-strain relationship of reinforcement is sensitive to buckling length. The aim of this study is to propose an analytical method to predict the buckling length of longitudinal bars restrained by lateral ties inside RC structures. Stability analysis is conducted giving due consideration to both geometrical and mechanical properties of the longitudinal and lateral reinforcements. The required tie stiffness is derived from energy principle and compared with actual stiffness to determine the stable buckling mode.
