Abstract: Japanese design code for highway bridges has adopted the allowable stress design concept which specifies the structures should be elastic against the design loads excluding the seismic loads. On the other hand there are some design codes in foreign countries that include the plastic design concept,which can contribute to the cost reduction of steel bridges. The final goal of this study is to establish the plastic design concept in Japan. In this research,considering the parameters in stress-strain relation of steel as random variables,Monte Carlo simulation is carried out in order to obtain the probability distribution of positive flexural strength of steel-concrete composite sections.
