摘要:
利用三维数字图像相关技术(3D-DIC)研究了一种新型半开口正交异性钢桥面板横隔板开口部位的疲劳性能.结合宁波舟山港主通道正交异性钢桥面板疲劳试验,对开口部位进行3D-DIC测量,得到了1 000万次疲劳加载过程的开口区域全场位移和应变数据.在此基础上,对位移场和应变场进行演化过程分析,得到了横隔板开口部位的疲劳性能演化规律.结果表明:1 000万次疲劳加载过程中,新型半开口正交异性钢桥面板横隔板开口部位未出现疲劳裂纹,新型结构的横隔板开口部位抗疲劳性能增强,并且能充分利用材料性能来抵抗疲劳破坏.但开口部位也出现了局部屈服现象,为防止实际应用过程中产生过大的塑性变形,其结构形式需进一步优化.
Abstract:
The fatigue performance of diaphragm openings of orthotropic steel bridge decks was studied by using 3D digital image correlation technology(3D-DIC).Combined with the fatigue test of the orthotropic steel bridge deck of the main channel of Zhoushan Port in Ningbo, the 3D-DIC measurement of the opening part was carried out, and the full field displacement and strain data of the open area of 10 million fatigue loading process were obtained. The evolution process of the displacement field and the strain field was analyzed, and the fatigue behavior evolution of the opening of the diaphragm was obtained. The results show that during the 10 million fatigue loading process, there is no fatigue crack in the opening of the diaphragm of the new semi-opening orthotropic steel bridge deck. The fatigue resistance of the new structure is enhanced, and thus the material performance can be fully utilized to resist fatigue damage. However, the local yielding phenomenon also occurs in the opening part. In order to prevent excessive plastic deformation during the actual application, the structure needs to be further optimized.
