钢筋锈蚀对空心板连接铰缝受力性能影响分析

Analysis of influence on mechanical behavior of hollow slab hinge joints caused by reinforcement corrosion

通过试验和理论分析,对空心板连接铰缝钢筋锈蚀对结构受力性能的影响进行研究。研究结果表明:在作用荷载不大时,铰缝内钢筋锈蚀对空心板间的连接作用影响不大,可将其与空心板作为一个整体共同参与工作;作用荷载较大时,铰缝内钢筋锈蚀使铰缝对空心板间的连接作用下降。

Through experiment and theoretical analysis, the influence of reinforcement corrosion of hollow slab hinge joints on the structural mechanical behavior was studied. The results show that when load is small the reinforcement corrosion of hinge joints has little influence on the connection between hollow slabs, and hinge joints will take part in the work with the hollow slabs as a whole. When load is larger, reinforcement corrosion of hinge joints makes the effect of connection between hollow slabs decrease.
