Dynamic Behavior of a Prestressed Concrete Bridge with a Switching Crack Subjected to Moving Trains
Concrete bridges chronically exposed to the natural environment are vulnerable to cracking. Under prestressing forces, the crack may close, but it will open under large dynamic loads, such as heavy trains. So the crack state can switch during the vibration. This paper investigates the nonlinear dyna...
