Dynamic Analysis of Curved Box Girder Deck Bridge in Autodesk structural Bridge Design 2024

Описание: Vibration of bridge structure under the passage of vehicles is an important
consideration in the design of bridges. Dynamic response of bridges has assumed added significance with the advent of faster and heavier vehicles and the use of structural forms and materials that permits the bridge to be more slender. Interaction between the vehicle and the bridge is complex dynamic phenomenon. This complexity results from the large number of different parameters that may affect the dynamic response .
During the past decades, extensive works have been under taken to study the factors affecting the dynamic response of bridges
investigation the influence of span, radius of curvature, span/depth ratio and the speed of moving load have been indicaed on the maximum values of dynamic factors for individual girders.
In 1997, Senthilvasan etal presented a simple procedure for modeling and analyzing the dynamic behavior of curved box girder bridges based on the curved spline finite strip
method, investigation the influence of several important parameters such as: The curvature of bridge, mass ratio (mass of vehicle/ mass of the bridge), speed of vehicle, support conditions, etc
