Abstract:
According to different steel yield points, respectively, an HPB235-node, an HRB400-node and a low yield point steel RC cross-shaped node were produced. By conducting low cyclic loading tests, the hysteresis curves of three nodes at the horizontal loading were got. Authors analyzed and compared with the energy dissipation capacity, ductility, stiffness degradation characteristics of three nodes. The test results show that the hysteresis loop area of specimen J-3 at the first cycle under displacement control of all levels is greater than specimens J-1, J-2; the displacement ductility factor of specimen J-3 is much larger than specimens J-1, J-2. A low yield point steel node has stronger energy dissipation capacity than an HPB235-node and an HRB400-node. The low yield point steel node is a marked increase ductility.
