| 内容記述 | Corrosion of the members of a steel structure leads to impairment of its operation and progressive weakening of that structure. Therefore, the effect of corrosion on the strength, stability and serviceability of hydraulic steel structures are of high concern among the bridge Engineers at present. The consequences of corrosion are many and varied and effects of these on the safe, reliable and efficient operation of structures are often considered than simply loosing of mass of metal. Various kinds of failures and the need of expensive replacements may occur even though the amount of metal destroyed is quite small. One of the major harmful effects of corrosion is the reduction of metal thickness leading to loss of mechanical strength and structural failure, causing severe disastrous and hazardous injuries to people. Since actual corroded surfaces are different from each other, only experimental approach to estimate the remaining strength of corroded members is not enough. Therefore, using of numerical analysis method should also be considered to have a reliable estimation, concerning the mechanical behavior, stress distribution and ultimate behavior which are not been clarified yet. But these analytical results will give important knowledge for not only the strength estimation but also subsequent repair and retrofitting plan. So a simple method to calculate the remaining yield and tensile strength by using a concept of representative effective thickness (t_<eff>) with the correlation of initial thickness (t_0) and the standard deviation of thickness (σ_<st>) is presented in this paper and the proposed effective thickness and strength estimation method, which based on the results of many tensile coupon tests of actual corroded plates and verified by numerical modeling results as well. | |||||
