  • Analysis on health inspection results and maintenance work cost records on road bridges

    Tamura Hiroshi, Wakabayashi Yukiko, Yamada Hitoshi, Katsuchi Hiroshi

    Journal of Structural Engineering, A ( Japan Society of Civil Engineers )  67 ( 0 )   464 - 478   2021

     View Summary

    <p>Analysis on bridge health inspection results and maintenance work cost records were conducted targeting road bridges in Kanagawa prefecture, which may provide a helpful perspective for estimation of future maintenance cost of bridges. The inspection results of 336 bridges were analyzed by type of structural members and implied tendency so that corrosion in steel girders and cracking in concrete girders and slabs progress relatively slowly but some types of concrete member deteriorations are found after escalation. The maintenance work cost record showed that total cost accumulation for repairing work of concrete bridges occurs rarely but drastically at one time. Besides, in steel bridges total cost accumulation for repairing increases slowly but steadily due to paint deterioration or corrosion.</p>

     View Summary

    Conducting a buckling experiment with the use of steel may provide high educational benefits in the experimental class of civil engineering course because it enables detailed observation and measurement, covering elasto-plastic buckling and offering extraordinary experience. This paper proposes a flexural buckling experiment with steel which possesses the degree of freedom as much as that of experiments for acrylic board, wood, paper and so on. This experiment also has advantages in cost and adjustability of the contents. This paper also reports the results of application of this experiment at the department of Civil and Environmental Engineering, Tokyo Institute of Technology. According to the results of the questionnaire survey, the experiment, especially the usage of steel, was highly evaluated by the students after the class.

     View Summary

    <p> In frictional type pretensioned bolted joints, one specification is employed for contact faces in each joint in principle. Meanwhile, in some cases such as protection works of existing bridges and fabrication of box girders made of weathering steel without coating, introduction of usage of different contact faces in one joint might often allow labor-saving and accelerated works.</p><p> In present study, bolted joints including different contact faces are defined as a hybrid faying surfaces joint, and 33 bolted joint specimens were used in bolt pretension relaxation test and slip test. This paper reports these results and compares degree of pretension loss and slip resistance in hybrid faying surface joints with homogeneous (i.e. normal) joints. Finally, also on the basis of previous research, the applicability and slip coefficient for designing of hybrid faying surfaces joints are discussed regarding.</p>

     View Summary

    <p> Relaxation of high strength bolted joints causes large bolt pretension loss at an initial stage of relaxation. However, the detailed characteristics had not been clarified. In this study, relaxation tests targeting many types of high strength bolted joints were carried out. Then, we investigated characteristics of bolt pretension loss at an initial stage of relaxation by literature search. From these results, we discussed the initial value setting method for relaxation tests in high strength bolted joints.</p>
