Über dieses Buch

This book presents both the fundamental theory and numerical calculations and field experiments used in a range of practical engineering projects. It not only provides theoretical formulations and various solutions, but also offers concrete methods to extend the life of existing bridge structures and presents a guide to the rational design of new bridges, such as high-speed railway bridges and long-span bridges. Further, it offers a reference resource for solving vehicle–structure dynamic interaction problems in the research on and design of all types of highways, railways and other transport structures.

Chapter 10. Dynamic Analysis of Train-Bridge System Under Beam Deformation Induced by Concrete Creep and Temperature Effect
Abstract
In this chapter, the influence of PC beam deformation induced by creep camber and temperature effect on the dynamic responses and running safety of HSR train-bridge system is studied. In this chapter, the influence of PC beam deformation induced by creep camber and temperature effect on the dynamic responses and running safety of HSR train-bridge system is studied. The numerical simulation method for PC beam creep camber is introduced. The vibration responses of train-bridge system excited by creep camber deformation are analyzed, and the safety threshold curves of creep camber under different train speeds are proposed, to ensure the running safety and stability of train vehicles. By numerical simulation and field measurement, the characteristics of bridge sidewise bending and track slab warping deformation under non-uniform temperature field are studied, and their influences on the dynamic response and running safety of the train-bridge system are investigated.
