CHUNGDAM GRAND Br. (Type Steel Frame Br.)

Profile of Model

Node: 34269
Element: 33732
Element Type: Plate

Design scope

An open shape, 190m long structural steel composite bridge consisted of 60, 70 & 60m long segments. A full model was created for the entire structure using plate elements. Detail Analysis was carried out to evaluate the effects of concentrated reaction forces on the diaphragm, which was open at the top. Pipe shaped bracing, U-shaped ribs and reinforcements at the support points were fully reflected in the model.

GULPO Br. (Steel Arch Br.)

Profile of Model

Node: 34269
Element: 33732
Element Type: Plate

Design scope

3D Solid Elements were implemented to represent a Lug-Pin connection part of a Cable Hanger of the Arch Bridge. Compression-Only Members and Gap Elements were used to resolve the contact Problem at Pin and Lug.

Detail Analysis Model of Transverse Tube connection to an Arch Rib. Beam elements were used at the boundaries of the detail model. Relevant displacements at the boundaries were obtained from the analysis of the entire model, which were then applied to the detail model as specified (forced) displacements.
