Dynamic analytical modeling of horizontal outline turn of T-girder simply supported bridge

Layout line of bridge structure is a direction line which is used to define the horizontal and vertical alignment of the bridge structure. The objective of this study is to evaluate and optimize the different designs of bridge horizontal outline turn and compare the results with horizontal layout...
