Analysis of moving loads using force-based finite elements

Creator:

Kidarsa, Adrian

Abstract:

An analysis method for moving loads computes the internal demand history in a structural member at integration points of force-based finite elements as opposed to the end forces of a refined displacement-based finite element mesh. The force-based formulation satisfies strong equilibrium of internal section forces with the element end forces...

Finite element modeling of reinforced concrete bridge columns with steel jackets using plastic hinge integration

Creator:

Carlton, Adam K.

Abstract:

In recent years confinement requirements for concrete columns have increased in seismic regions. Steel jackets are one way to confine reinforced concrete columns. The increased confinement provides additional strength and ductility for the columns during seismic events. For reinforced concrete columns with steel jackets, there are different section properties in...

3-D finite element modeling in OpenSees for bridge live-load girder distribution factors

Creator:

Scoggins, Luke A.

Abstract:

A generalized, three-dimensional, finite element bridge model was created in order to efficiently and accurately assess live-load girder distribution factors for a variety of bridge types. This model shortens the time required by bridge analysts to develop individual finite element models for bridges of varying geometries. The creation of the...
