| 7. | The conclusion of reappearing analysis is that crane bridge be used as usual because main weld maximum stress of upper cover plate of main beam lower than yield limit though it higher than permissible stress . inner stress of secondary beam was over ultimate strength , and deforming is ultra big . so it was unfit for produce and secondary beam must be changed
再现分析得出的主要结论为：桥架的主梁上盖板主焊缝的最大应力超过了许用应力，但小于屈服极限，可以继续投入使用；副梁内部的应力远远超过了强度极限，变形特别严重，不能满足生产要求，因此更换新的副梁；端梁内部的应力超过了屈服极限，小于强度极限，在应力较大的位置焊接补强板；投入使用后，要对整个桥架进行定期检查。 |
| 8. | Comparing with these several strengthen formal , towards strength limit ' s improvement , the effect of torsion - tension and tension - torsion - tension was close ; simply tension - torsion - tension required a little larger prestrain quantity . whereas , towards yield limit " s improvement , the effect of torsion - tension - tension action ' s strengthen was the best
从几种硬化形式的比较来看，对于强度极限的提高，扭转-拉伸和拉伸-扭转-拉伸的强化效果相近，只是拉伸-扭转-拉伸所需的预应变量要大一些；而对于屈服极限的提高，扭转-拉伸-拉伸作用下的强化效果最佳。 |
| 9. | When the a3 steel specimen was operated by tension - torsion - tension action , both the yield limit and strength limit had very large improved compared with that of monotonic tension . the improve scope of the yield limit could be 109 . 36 % , the strength limit could be 56 . 26 % . the yield limit value reached the max
A3钢试件在拉伸-扭转-拉伸作用下的力学性能与单一拉伸相比，试件的屈服极限和强度极限都有很大提高。屈服极限提高幅度最高可达109 . 36 ，强度极限提高幅度最高可达56 . 26 。 |
| 10. | After pretorsion the successor tensile yield limit and strength limit both improved very highly , but the trend of the increase of the strength limit was suspended till the pretorsional capacity reached 17 , when the pretorsional capacity was greater than17 ( prestrain value was 81 . 19 % of total strain ) , the successor strength limit rapid failed and approached the yield limit . this illustrate the a3 steel specimen translate from plasticity into friability after pretorsion strengthen . when the specimen was operated by tension - torsion action , the yield limit had very large improved , but the strength limit changed very little . furthermore , the trend of the increase of the strength limit was suspended till the pretension capacity reached 0 . 25 ( prestrain value was 66 . 93 % of total strain )
A3钢试件在预扭转后，后继拉伸屈服极限和强度极限均有很大提高，但强度极限的增大趋势到预扭转量为17为止，预扭转量大于17 (预应变值为总应变的81 . 19 )后强度极限迅速下降，与其屈服极限接近，这说明a3钢试件经预扭转强化后逐渐由塑性转化为脆性。该预应变值为a3钢试件的韧脆转变点。 a3钢试件在拉伸-扭转作用下，屈服极限有很大提高，但强度极限没有多大改变，而且，屈服极限的增大趋势到预拉伸量为0 . 25应变(预应变量为总应变量的66 . 93 )后就不再增加。 |
