| 6. | By the use of dynamic buckling supplementary restraint conditions at the compression wave front of cylindrical shells at the instant when the buckling occurs , the critical load and dynamic buckling modes of shells were calculated from the solutions of finite element characteristic equations 计算结果揭示了圆柱壳弹性轴对称动力屈曲变形发展的机理,以及轴向应力波和屈曲变形的相互作用规律。 |
| 7. | Thin board will have flexure transmutation in part and drop out load when the stress of thin board goes up to the steady critical value , resulting in losing stabilization wholly . 5 . it is the first time to construct a set of monitoring system of cranes mainly on the flexibility and vibration in our country 薄板在迭加后压应力的作用下,当达到稳定临界值时,板的局部将出现屈曲变形而退出承载,由于板的承载截面减小导致金属结构的整体失稳; 5 、建立的一套以应变监测和振动监测为主的门座起重机状态监测系统,在国内门座起重机上尚属首次。 |
| 8. | Experimental results show that the new cfrt - column to steel - beam joints proposed in this paper possess good earthquake resistant capacity . the infilled concrete benefit to restrain the buckling deformation of column webs , increase the strength and stiffness of the joint . the lengthened stiffener can transfer much more beam moment , make the strength of the joint increased 试验表明,在保证焊接质量的前提下,本文提出的新型方钢管混凝土柱?钢梁的节点具有良好的抗震性能;内填混凝土有利于抑制柱腹板的屈曲变形,增加节点的承载力和刚度;加劲肋长度的增加有利于传递梁端弯矩,使节点的承载力提高。 |
