针对低-中震害区构件有限延性的要求,提出了2种新型钢筋混凝土梁柱节点的构造形式:在节点区加配斜钢筋,或梁主钢筋在节点区弯起.它们既可满足有限延性的要求,又可避免节点区钢筋密集.通过对4个高强混凝土梁柱节点在低周反复荷载作用的试验表明:2种新型节点均可提高节点延性,将节点的位移延性系数分别从3提高到3.5和4.4;在节点区加配斜钢筋的试件可提高强度15%.因此,对于有限延性要求的节点,是最佳的节点构造形式.

Aiming at the requirements of limited ductility of components in low-medium seismic damage areas, two new structural forms of reinforced concrete beam and column joints are proposed: oblique steel bars are added in the node area, or the main steel bars of the beam are bent in the node area. They can not only meet the requirements of limited ductility, but also avoid dense reinforcement in the node area. The repeated loading of four high-strength concrete beam and column joints at low cycle shows that the ductility of the two new joints can be improved, and the displacement ductility coefficients of the joints are increased from 2 to 4.2 and 3.3, respectively. The strength of the specimen with oblique steel bar can be increased by 5% in the nodal area, so it is the best joint construction form for the node with limited ductility requirement.
