摘要
本文提出了框架结构梁端纵向受力钢筋在节点中锚固滑移所产生的附加转角的简化计算模型,并在梁柱组合件试验所获得的杆端弯矩-滑移转角滞回曲线基础上建立了杆端弯矩-附加滑移转角恢复力模型。该恢复力模型包括一条基于计算的双线型骨架曲线和一系列基于试验现象的滞回规则。计算结果与试验结果的比较表明,本文提出的杆端弯矩-附加滑移转角恢复力模型可以较好地反映试件的滞回性能,可供框架结构弹塑性地震反应分析时参考。
This paper presents a simplified analytical model for simulating hysteretic moment-anchorage slip-rotation relationship of RC frames. The primary curve of the moment-anchorage slip-rotation relationship is constructed by computing the extension of tension reinforcement in the beam-column joint and the bond decay under cyclic loading is considered based on test data. A series of hysteretic rules are obtained from experimental hysteretic curves. A comparison of experimental and analytical hysteretic relationships indicates good agreement.
