中文摘要	介绍了3个钢筋混凝土梁-钢管混凝土组合柱节点试件在梁端竖向往复荷载作用下的试验研究,其中一个为梁弯曲破坏的"强核芯区弱梁"试件,两个为核芯区剪切破坏的"强梁弱核芯区"试件。试验结果表明,三个试件都有大的变形能力,但峰值荷载时弱核芯区试件的核芯区剪切变形占节点总变形的50%以上,而强核芯区试件的这一比例很小;弱核芯区试件核芯区的箍筋和钢管屈服,而强核芯区试件核芯区的箍筋和钢管未屈服;弱核芯区试件的耗能能力小于强核芯区试件的;对于核芯区破坏的试件,减小核芯区的箍筋间距,可以增大节点的耗能能力和减小核芯区的剪切变形。; Tests about three reinforced concrete beam-composite steel tube confined concrete column joint specimens under cyclic loads at the beam cantilever ends are introduced.Among three specimens,one was strong core and weak beam specimen,and two were strong beam and weak core specimens.Test results show that all specimens have large deformation capacity,but at the peak load more than 50% of the total deformation of the weak core specimens is contributed by the shear deformation of the core,while this ratio of the strong core specimen is small. The stirrups and the tube in the core of the weak core specimens yield while those of the strong core specimen do not yield.The energy dissipation capacity of the weak core specimens is smaller than that of the strong core specimen.For the weak core specimens,reducing the stirrup space can increase the energy dissipation capacity and decrease the shear deformation of the core.; 国家自然科学基金重大研究计划重点项目(90815025)
