Transcript of Copy of CSI Bridge

CSI Bridge
Integrated 3-D Bridge
Design Software

Bridge Modeling and Analysis
work required:
Tee girder
length : 32m long
span : 2

Template
starting a new bridge model or structure
Layout Line
For a Quick definition of highway layout and Flexible and powerful control over bridge geometry we use
Superstructure Variation
prepared by
: Praveen Kumar.T

introduction
CSiBridge design allows for quick and easy design and retrofitting of steel and concrete bridges
Modeling, analysis and design of bridge structures have been integrated into CSiBridge to create the ultimate in computerized engineering tools
CSiBridge includes an easy to follow wizard that outlines the steps necessary to create a bridge model
Default definitions of all properties, components, loading definitions, design settings, and other defined items
define the layout line
specify the end end station
Specify a variation for all or parts of the bridge alignment and slope.
for our model we will use the
straight line geometry
Define the lane line
2 lane
each lane is differntiated with different colour
and pathway lane size is defined by considering kerb size , parapet railing
Parametric Deck Sections
Vary geometric parameters to easily modify deck and girder arrangements.
tee beam concrete
girder
we select the girders vertical
Total width: 8.7m Total depth: 1.65m
Diaphragms
Multiple diaphragm options to choose
Solid diaphragm for concrete bridges
we enter Diaphragm for the
diaphragm name and leave the
other data fields at their default settings.
Parametric Variations
Specify a variation for all or parts of the bridge alignment and slope.
Left Span Variation
Components
Substructure
Bearing
we define the Bridge Bearing name
then we modify the users
bearing (translation
along layout line (U3)
Foundation
we define the foundation spring name
and we leave the
other data fields
at their default settings.
Abutment
firstly we must define the frame properties
Frame section type propriety
: Concrete
Concrete Section
: Rectangular
Define the section name and dimensions
section name
: Abutment
depth:
8ft
width:
4 ft
Define the Bridge abutment name
substructure type :
Continuous Beam
Section property :
abutment
Beam length :
30 ft
Foundation spring
: type Foundation
Define Column Section
Frame section property :
circular section
Section name :
Column
Diameter :
5
Define the Bentcap section
Frame section property :
rectangular section
Section name :
Column
Depth:
10
Width:
5

Bent
Girder support condition :
integral
Bent Data:
Cap Beam length :

30
Number of Column :
3
Cap Beam Section :
Bencap
then we modify the column Data
Load
then we select the vehicle class
we define the loads patterns
Load patterns Name :
truck
Type : vehicle live
we specify the vehicle type
Bridge
from the bridge object assignments we get:
Pres tress Tendon:
Tendon assignment
modify Tendon parameter
Run Analysis
Deformed shape
Results
deformation with value
