摘要
在国内外研究的基础上，设计了两个无粘结预应力扁梁边柱节点试件，并进行了低周反复加载，对试件的破坏过程和破坏形态、试件的承载力及刚度退化、延性与耗能、应变分析等问题进行了研究。提出了实用的设计建议和配筋构造措施。
Two wide-flat beam-column joints under the low reversed cyclic loading were tested to investigste the following properties: failure process and failure state, strength stiffness reduction, ductility, energy dissipation, analysis of strain of non-prestressed bars and prestressed tendons, etc. Based on the results of the tests, some recommendations are presented.
