Analysis of a continuous multicellular curved bridge deck using grillage analogy method

The use of curved bridges in interchanges of modern highway systems has become increasingly popular for economic and aesthetic consideration. This research presents a comprehensive study on the analysis of a continuous multicellular bridge deck using Grillage Analogy Method. The elevated u-turn brid...
