; 文章编号:1672-7207(2014)12-4292-08 Probabilistic optimum inspection and maintenance strategy for reinforced concrete bridges due to reinforcement corrosion ZHOU Hao1, HUANG..., ME4 4TB, UK) Abstract: Focused on the deterioration of reinforced concrete (RC) bridges due to reinforcement corrosion, the damage intensity of structure based on local pit depth of reinforcement......
of 13 square hollow section (SHS) X-joints with different β and different types of plate reinforcement under in-plane moment in brace was carried out. Experimental test schemes, failure modes of specimens, moment-vertical displacement curves, moment-deformation of the chord, and strain strength distribution curves were presented. The effect of β and plate reinforcement types on in-plane flexural......
, UK) Abstract: For the deterioration of reinforced concrete (RC) girder bridges due to reinforcement corrosion, the corrosion depth of reinforcement was used to characterize the performance... of detection (PoD) of reinforcement corrosion and maintenance, the service life prediction model was proposed. The inspection and maintenance cost model was also proposed based on the inspection......

of ballasted track of different stiffness sections using polyurethane ballast reinforcement technique QI Wei, LIU Yutao, LI Chenghui (Key Laboratory of High-Speed Railway Engineering, Ministry... reinforcement technique was adopted to form a continuous and even stiffness transition in the ballasted bed which was divided into three different stiffness sections. The dynamic test was carried out......
of reinforcement treatment to the combination section was also discussed. The results show that to some extent, the stability of the combination section between new and old embankment depends on the slop of roadbed and the width of the new constructed embankment. But the unequal settlement depends on the thickness of the new constructed embankment. Reinforcement treatment to the combination......
was verified.The results show that the flexural capacity of PC beams decreases with the increase of corrosion. The yield of prestressing tendon in the ultimate state depends on the reinforcement index and corrosion degree. The corroded strand can yield when the reinforcement index is less than 0.23. For the large reinforcement index, the effect of corrosion on the strength utilization coefficient of the corroded......
