Synopsis "Vehicle-Bridge Coupled Vibration (in English)"
When a vehicle is driving on a highway bridge, it causes the bridge to vibrate, thereby affecting the vibration of the vehicle. This interaction and influence represent the coupled vibration between the vehicle and the bridge. From the perspective of dynamics, a car is a multi-degree-of-freedom vibration system composed of a car body, wheels and suspension system. Due to the weight of the vehicle and the unevenness of the bridge deck, the moving vehicle has a dynamic impact on the bridge structure, forcing the bridge to vibrate, which in turn affects the vibration of the vehicle. In this way, the vehicle and the bridge influence each other through the contact between the wheels and the bridge deck, thereby forming a complex multi-degree-of-freedom coupled vibration system.Dynamic performance of different bridges subjected to moving vehicles are conducted in this book, including of simply-supported girder bridges, continuous girder bridges, steel-concrete girder bridges, rigid bridges, concrete-filled steel tube arch bridges, large-span cable-stayed bridges, large-span suspension bridge. Also, dynamic load allowances corresponding to different responses in different positions of highway bridges under moving vehicular loads are deeply discussed. In addition, some key points on design, construction, reparation, and maintenance of highway bridges are detailedly discussed.This book can be used as a teaching book for civil engineering majors and transportation engineering majors, and can also be used as a reference for technical personnel of related majors.
