Construction If the construction of girders and cross frames needs to be divided into multiple stages, this component can be utilized. However, during the typical design process of steel I-girder bridges, a detailed analysis of the erection sequence for girders and cross frames is usually not necessary. Engineers who are responsible for girder erection typically conduct this detailed analysis after the design processdone in several stages (or, in other words, if segmental girder construction is required for various purposes), this object can be used.
Girder Erection
Is Closure?[Yes/No]: Choose 'Yes' if the closure segment station information has been entered. For the closure segment, “Cast Stage” and “Stiffness Stage” information is collected since the load is applied first, and then stiffness is gained. For other segments, stiffness and weight are applied at the same stage, so only one stage is selected.
