| 摘 要： | 在疲劳荷载作用下力学损伤的不断累积会引起混凝土结构的疲劳破坏.在腐蚀环境中,腐蚀介质会造成钢筋锈蚀.钢筋锈蚀对混凝土结构疲劳性能的影响比其对静态性能的影响更加严重,这是因为锈蚀削弱了钢筋的有效截面,而且钢筋锈坑的不均匀性导致了钢筋应力集中,相应地疲劳荷载作用会加速腐蚀介质的渗透过程,从而加剧混凝土构件的损伤,降低混凝土耐久能力.

| Abstract: | The action of fatigue load leads to the damage of concrete structure,mechanical damage to accumulate the results of a large number of projects in recent years.The survey showed that the corrosion environment,corrosion medium will cause steel corrosion.The influence of steel corrosion on concrete structure fatigue properties is more serious than that of static properties.Because corrosion weakened the effective cross-section,and rust pits nonuniformity will lead to reinforcement stress concentration,correspo... |
