A Simplified method to minimize exterior girder rotation of steel bridges during deck construction
Engineering Structures（2019）
Abstract
•More than four thousand finite element models are built by varying bridge geometries.•Stepwise variable selection method is used to remove the redundant parameters.•Effects of bridge geometrical parameters are inspected.•Three regression models are developed and compared.•A simplified method for determining the B/D ratio is developed and validated.
