Dynamic Amplification Factors for Bridges with Various Boundary Conditions

Bridge & Infrastructure Research in Ireland 2010, Cork Institute of Technology, September, 2010It is important that the assessment of bridges be as accurate as possible. Dynamic amplification is one area in which the codes are sometimes overly conservative. Bridge dynamics is well researched but the majority of this research has concentrated on simply supported bridges. This paper examines the effect that introducing support rotational restraint has on bridge dynamic amplification factors. Finite element models are used with rotational springs at the bridge supports. This paper examines the effect of vehicle velocity on the dynamic amplification for the different end restraints.Deposited by bulk importTS 11.02.1
