混凝土框架柱塑性铰区域剪切破坏形态的试验研究
|
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,详细研究了塑性铰区的主要破坏形态、主要破坏特征及其发生条件,讨论了构件塑性铰区主要破坏形态的分类标准,为混凝土框架柱的抗震延性设计提供了试验依据。
The deformation limits of columns designed according to following current codes of many countries is dominated by concrete crushing or longitudinal reinforcement buckling within yield hinge regions near the column ends,rather than shear failure.But the seismic investigation of the columns shows the unavoidable shear failure of the columns.For more reliable design method of ductility reinforced concrete columns the shear tests of 10 columns and analysis under cyclic load have been made.In the article the suffering failure of columns within yield hinge re- gions and classified standard are expressed in detail to end the confusion of expression and application in the seis- mic ductlity design of the concrete frame column in China.
