为了使梁的延性充分发挥，试验研究了梁内主筋在节点核芯区的不同的锚固方案以及装配式节点中梁内主筋的坡口焊焊接方法。
For the full development of beam ductility, different kinds of anchorage of beam reinforcements in the joint core and groove welded connction on longitudinal main beam b…
在其他条件都相同而核心区配箍率不同的情况下，核心区配箍率越小其损伤值越大，其延性也越差。
If the rate of stirrup used in core area is smaller and the damage is larger, the ductility is worse.
试验结果表明，随着受拉区非预应力筋配筋率和预应力筋配筋率的增大，梁的延性逐渐减小；
The experimental results show that the ductility of the beams decreases gradually with the increasing of non prestressed and prestressed reinforcement index in the strained zone;
中强匹配接头蠕变断裂位置在远离焊缝界面的低强度母材区，呈延性断裂性质。
However, the creep fracture of medium strength match joint, located in the low strength base metal remote from the weld interface, showed a ductile fracture character.
