| 摘 要： | 允许钢筋混凝土框架柱端出现塑性铰但又不形成柱铰破坏机构是一个十分现实而又未得以很好解决的课题。通过10个钢筋混凝土框架柱构件抗震剪切抗力的试验研究，明确了加载全过程骶架柱构件中箍筋与混凝土的抗剪贡献及比例，分析了框架柱塑性铰区抗剪机理，为框架柱基于延性的抗震设计提供了试验依据。

| Abstract: | For the design of ductile reinforced concrete columns in seismic zones the shear tests of 10 columns within yield hinge regions have been made. In the article, the shear contribution of concrete and transverse reinforcement as to cyclic shear numbers and displacement ductility level is investigated in detail. With the developing of the test the shear contribution of concrete is decreasing, while the shear contribution of transverse reinforcement is increasing till columns' failure. The shear mechanism of columns within yield hinge regions is also researched. All of conclusions can be used for reference of revising the CONCRETE STRUCTURE DESIGN CODE. |
