摘要 为研究钢混组合梁焊钉部件在腐蚀环境下锈胀诱发混凝土板开裂的行为,基于内聚力模型理论,利用全局插入内聚力单元的方式建立焊钉局部锈胀模型。通过对焊钉位置、直径、间距等参数的分析,研究各参数对混凝土板锈胀力分布、裂缝面特征及开裂过程的影响。结果表明:组合梁内部焊钉,在锈蚀中后期锈胀影响区内的混凝土将产生大量微裂缝,混凝土表面呈现局部网状开裂;焊钉直径从16 mm增加至25 mm,初始裂缝开裂时锈胀力减小了0.82倍;当焊钉纵横间距比大于2时,自由边水平方向产生多条斜裂缝;全局插入粘性单元的有限元模型可以有效且直观的模拟锈胀开裂过程。

Abstract: To investigate the cracking behavior of concrete resulting from rust expansion of anchor bolt components in a corrosive environment within reinforced concrete composite beams, a local rust expansion model of anchor bolts was established using the cohesive force model theory and global insertion of cohesive elements. Analyzed anchor bolt parameters such as position, diameter, spacing, and then examined their impacts on the distribution of rust expansion forces, characteristics of resulting cracks, and the overall cracking process in concrete. The findings indicated that an increased anchor bolt diameter should lead to a reduction in rust expansion force at the initial cracking stage. Specifically, augmenting the anchor bolt diameter from 16 mm to 25 mm resulted in an 82% decrease of the rust expansion force at the onset of initial cracking. When the longitudinal and transverse spacing ratio of anchor bolts is greater than 2, multiple diagonal cracks emerged in the horizontal direction of the edge. The finite element model with global insertion of cohesive elements effectively simulates the rust expansion and cracking process.
