| 摘 要： | 提出一种框架梁端腹中开水平缝新型人工塑性铰方案,且建立了其内力和承载力计算公式.并在此基础上,进一步分析了该人工塑性铰的转移条件、开缝位置及开缝长度,分析并提出了该新型人工塑性铰的延性系数计算方法,计算结果与试验结果比较,吻合较好,完善了该人工塑性铰的设计理论.，Opening horizontal slit in the middle web of the beam end formed a new type of artificial plastic hinge. The calculation formulas about the hinge's interior force and bearing capacity are set up. Based on these, the condition of transfer, the location of crack and the cracking length of the artificial plastic hinge were studied further. The calculation method for the ductility factor was also presented. The calculation results and the test ones were compatible.
