中文摘要：

利用有限元软件ADINA对一栋6层现浇钢筋混凝土框架结构的梁柱节点做了拟静力分析与地震动力反应分析,并对普通梁柱节点与周围楼板设角缝节点的结果对比。分析计算结果表明,对于普通梁柱节点,在梁柱节点处采用开角缝的措施之后,梁受力主筋屈服明显提前,柱混凝土裂缝明显减少,梁、柱塑性铰出现时间间隔增加。首层柱柱脚处塑性铰的出现延后,更加接近总体机制破坏。

英文摘要：

A numerical quasi-static and dynamic earthquake response model was established with ADINA software for beam-column interior joint in a reinforced concrete frame.The results for traditional joint specified in design code and that for the joint with slot around were compared.It is shown that for the joint with slot around,the yielding time of beam reinforced bar will shift to an earlier time,while the number of cracks on column becomes less.The time interval between the occurrence of plastic pivot on beam and on column becomes longer,which exhibits a failure type closer to the beam-pivot mode.
