プレキャスト・プレストレストコンクリート柱の復元力特性に関する実験的研究

抄録

In this paper, cyclic reversed loading tests were conducted in order to investigate the hysteretic behavior of the precast prestressed concrete columns subjected to bending and shear. The test variables include : prestress at the centroid of a section, an axial force, an amount of confinement reinforcement ratio and an existence of a joint. On the basis of the test results, a rigorous restoring force characteristics model was presented for the different prestress and axial force. This model coincides well with the test results, in term of the shape of the hysteretic loop and hysteretic damping. Furthermore, the validity of this model was verified by comparing this model with 66 previous systematic test results.
