Time Dependent Material
|
- 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.
|
| |
|
 |
| |
Time-variant
concrete strength as per various standards (ACI, CEB-FIP,
etc.)

|
- Analysis based on time-variant
concrete strength
- Capability of Refined analysis of Creep & Shrinkage
in a given Stage.
- Database constructed for various
codes for easy application.

Sectional Property Calculator
|
| |
|
Sectional Property Calculator
calculates section properties
of unconventional section shapes, which are imported by
Section Import during
structural modeling.
|
Sectional
Property Calculator reads in an AutoCAD DXF file to
calculate the sectional properties of a complex section
|
|
|
| |
|
A
number of sections are arranged by sizes, and their
section properties are calculated individually
|
- Import data files in the
format of AutoCAD DXF
- Simple data entry using versatile modeling capabilities
- Fully automated mesh generation for the defined
sections to calculate the section properties
- Calculation of Hybrid sections
composed of different materials

PSC Box Section & Tapered
Section
|
| |
|
MIDAS/Civil provides Standardized
PSC Box Sections for PSC Box Girder Bridges
for easy application in practical modeling and analysis.

|
Definition
of a Standardized PSC Box section by specifying basic
dimensions
|
| |
|
|
| |
|
Simply
defining the start/end sections of a non-prismatic member
automatically generates intermittent sections
|
- Where variable sections exist in a member such as
a FCM bridge, section properties
are automatically calculated upon defining
the end sections and the rate of curvature.
- Longitudinal & transverse variable sections
can be specified.
- When auto-generated variable section data are partially
modified, the related sections are automatically revised.
- Effective widths are automatically
calculated as per design codes and subsequently applied
to analysis.

Tendon Placement for Prestressing
|
- Calculation of prestress
loss of tendons of 3D Profile and Curvature
- Prestressing effects considered
for Pre-/Post-tension and Internal/External placing
methods
- Free tendon placement irrespective of nodes
|
| |
|
|
| |
|
Automatic
Placement of 3D tendons based on reference points, counter-flexure
points and eccentricities at a particular position
|
| |
|
|
| |
|
Tendon
Placement may be confirmed at relevant transverse cross
sections.
|
| |
|
 |
- Tendons may be freely
placed and checked on transverse cross sections.
- Short-term prestress losses considered for
the effects of anchor slippage of tendons, friction
between tendon and sheath and elastic concrete
shortening
- Long-term prestress losses considered for
the effects of Creep, Shrinkage and Relaxation
of tendons
- Variation of prestressing in tendons considered
for the effects of loading and temperature changes
