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.

MIDAS/Civil provides
the Wizard to create a completed
model of a Cable Stayed Bridge extremely fast. Initial prestressing
forces are calculated through Optimization
for initial equilibrium state analysis. It also provides the
Construction stage function, which
enables us to reflect Creation/Deletion of elements, change
in boundary conditions and loading changes that may occur in
various stages of construction.

Unlike conventional structures,
a special analysis approach is required for Suspension Bridges,
which are composed of flexible cables. Suspension
Bridge Wizard in MIDAS/Civil automatically calculates
the cable coordinates and tensions of the completed structure.
Also, using 3D Elastic suspension line element and Equivalent
truss element can consider nonlinear characteristics of the
cables. It supports Geometric nonlinear
analysis as well as Construction
stage analysis.

scope
A structural analysis model of existing Youngjong
Bridge was created for the purpose of maintenance management
during its life cycle. Cable and Beam elements were used
for the superstructure.
Elastic Links and Rigid Links were used to represent the
boundary conditions. The entire structural model was tuned
to represent the true behavior of the bridge, reflecting
the displacements and natural frequencies measured from
a series of load tests. |

Time dependent material
properties are defined to reflect the variation of modulus of
elasticity relative to concrete maturity and the long-term deflection
effects due to creep and shrinkage. MIDAS/Civil provides Standardized
PSC Box Sections for Post-tensioned Box Girder Bridges
for easy application in practical modeling.
Analysis accounts for prestressing effects considering Pre-/Post-tension
and Internal/External placing methods. FCM,
ILM and MSS Bridge models and construction stages are
generated after having entered only cross sections, tendon placement
and bridge information.
