Finite element evaluation of pier moment--rotation characteristics in continuous-span steel I Girders

摘要

This paper summarizes the implementation and execution of a reasonably comprehensive set of finite element parametric studies to fill in knowledge gaps in the available experimental data Per- taining to the hogging moment--plastic rotation behavior of steel and composite steel--concrete bridge girders. The paper highlights key requirements for proper finite element modeling of the behavior, outlines the design of the finite element parametric stud- ies, and presents the important 畁umerical test' results. Based on the finite element predictions, simple moment--rotation relation- ships are developed for use in design and rating of bridge Struc- tures.
