Modelagem estocástica do comportamento dinâmico de tabuleiros rodoviários submetidos ao tráfego de veículos

In this paper an analysis methodology is developed to evaluate the dynamic response on highway bridge decks due to vehicles crossing on the rough pavement surfaces. The analysis methodology follows a statistical model running in the time domain. The mathematical model simulates the bridge structure...

The analysis methodology follows a statistical model running in the time domain. The mathematical model simulates the bridge structure and the vehicle series as a system, the vehicle-bridge system.
