Abstract

<p> From the revision of the Specifications for Highway Bridges in 2017, it was required to consider Level 2 earthquake ground motion for the Verification of the decks. In the calculation example corresponding to the Specifications for Highway Bridges, the verification result was shown when the deck bears 100% of the sectional force generated in the superstructure This design method may be significantly more unreasonable than the previous design method. In this study, partial FE analysis was performed using a solid element for the reinforced concrete deck and a shell element for the main girder. At the same time, a frame analysis using fiber elements was performed. Based on the analysis results, it was confirmed that the decks and the main girders were integrated to resist the lateral load. Then, the load sharing rate was evaluated.</p>
