| 6. | The results are that the maximum displacement and maximum stress occurs at initial time and the maximum stress is less than permissible stress
结果表明,结构最大应力和最大位移均发生在初始时刻,最大应力小于许用应力。 |
| 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。 |
