| 摘 要： | 利用有限元软件ANSYS建立考虑箍筋间距、直径变化的钢筋混凝土构件锈胀裂分析模型,研究箍筋对纵筋锈蚀导致钢筋混凝土构件保护层胀裂的影响.结果表明:箍筋间距在100 mm以上时,对引起纵向裂缝的最大锈胀力影响很小,.但对裂缝产生的位置有一定影响,即箍筋位置处首先出现裂缝的可能性最小,而相邻箍筋中间位置处可能性最大;箍筋间距在50 mm以内时,能有效抑制或延缓试件表面纵向锈胀裂缝的产生,箍筋直径变化对保护层纵向锈胀开裂影响甚微. |

| Abstract: | Considering the change of the spacing and diameter of stirrups,a corrosion-induced cracking module for concrete members is built by ANSYS.The effect of the stirrup on cracking of concrete cover due to longitudinal reinforcement corrosion is analyzed,and the following conclusions are reached.The peak value of the corrosion pressure inducing longitudinal crack is influenced slightly by spacing of stirrups over 100 mm,but the position of cracks is influenced remarkably.In fact,cracks appear firstly at the loca... |
