Dynamic analyses of composite footbridges excited by pedestrian induced loads

In this study, various types of human running dynamic loads are numerically studied and compared to assess serviceability characteristics of light and slender composite footbridges, with and without the implementation of Textile Reinforcement Concrete (TRC) as compliment composite material. Running,...
