To　investigate　the　effect　of　loading　rate　on　the　bond　capacity　between　corroded　reinforcement　and　concrete,16　RC　beams　(mass　loss　rate　of　0%—8.　7%)were　tested　under　different　loading　rates　(0.　5—300　mm　/　min).　Based　on　the　above　data,the　bond　strength　prediction　model　was　proposed　incorporating　the　effect　of　loading　rate　and　steel　corrosion.　Meanwhile,the　bond　capacity　of　corroded　RC　beams　was　numerically　simulated,in　which　the　effects　of　high　loading　rates　(30—30　000　mm　/　min,strain　rates　of　10-4—10-1　s-1)were　analyzed.　Results　show　that:　(1)loading　rates　rarely　influence　the　shape　of　the　bond　stress-slip　curve　of　corroded　RC　beams,and　the　ratio　of　the　bond　strength　over　the　residual　bond　strength;(2)with　the　increase　of　loading　rate,the　bond　strength　and　residual　bond　strength　between　corroded　steel　and　concrete　significantly　increase,and　the　steel　stress　at　peak　within　the　bond　zone　obviously　increases　with　gradually　approaching　the　loading　end;(3)the　proposed　bond　strength　prediction　model　incorporating　the　effects　of　loading　rate　and　steel　corrosion　can　be　applied　within　the　loading　rates　of　0.　5—30　000　mm　/　min.　©　2024　Cailiao　Daobaoshe/　Materials　Review.　All　rights　reserved.
