RM Wizards

RM Wizards


RM
Wizards are regular data
objects in
the RM data file.



One
RM Wizard item is
stored as one
“parent
” object: a whole bridge
structure.



RM
Wizards will open the connection
to
other products (LEAP
, BridgeKey)
or
interfaces (ISM)








RM Wizards



For non
-
experienced RM user, Wizards should
be understood as
a “Press button”
solution.



For experienced RM user the situation is
different: experienced user will be able to
understand and manipulate generated data
for his special purposes.









RM Wizards



Wizard will automatic generate
data:


Structural model,


Loading definition,


Construction sequence


Calculation of all loadings and load combination


Data for design code checks


Results in form of sheets, diagrams, plots and
drawings.




This automatic generation is following
predefined rules, so user can understand his
outputs.






RM Wizards: Configuration


RM Wizards are designed as following:



User can always go back to dialogs and
change data again



User should normally not change or
manipulate wizard generated data
(structure, loading etc)



Instead of changing generated data, user
should go to original wizard input.




RM Wizards: Design Codes


RM Wizards are designed as following:



Separate dialogs for separate design codes



Currently
implemented AASHTO and
EUROCODE.



Other design codes will follow.


RM Wizards: Superstructure


Each
superstructure has its
own (specific
) definition:
Prestressed Girder,
Reinforced Slab, Steel
Girder Concrete Slab, Steel
Girder Steel Deck.




Although input for
superstructure is specific
for different bridge decks
the whole input sequence
is driven in
similar way

RM Wizards: Substructure


The
sub
-
structure
definition is common for
all wizards.



Drop Cap Pier,
Hammerhead Pier and
Wall Pier are available.



Fixity of support is
controlled within the
wizard.



Complex
logic of
connecting separate
structural part is
implemented
within RM.


RM Wizards: Loads


Self
-
weight, Live,
Traffic, Braking and
Temperature load are
defined in the Wizard.



Seismic loads are
defined with the
Response Spectrum
Method.



Pier settlement and
bearing replacement
are also considered.



Creep and shrinkage
effects during
construction and final
can be defined.


RM Wizards: Analysis



Three different level of
modeling and analysis
are predicted:


Beam


Grillage


Detailed FEM



Current implementation
is beam and
grillage
model.
FEM will follow in
next
release.

RM Wizards: : Future Development


Special Loads

1.
Allowing the user to consider other loads than
standard loads of design codes.

1.
Abnormal convoy

2.
Accident action

3.
Earth pressure

4.
Ice pressure

5.
Vessel collision

6.
Dynamic wind action

2.
Allowing defining special design combinations

1.
Distinguish ordinary actions and

2.
Extraordinary actions (different safety requirements)

3.
Combinations for bearing design only

4.
Design forces for local proof checks (e.g. lateral bending of
slab)

Demonstration





RM Draw Manager

RM Draw Manager


RM Draw Manager is an automated plans
generation tool inside RM Bridge.



Extracts information and results from the
RM Bridge Model and assembles that into
user defined plan sheets.



Plan sheets are CADD files in
Microstation or AutoCad format (dgn,
dwg).



CADD 3D Models are also generated

RM Draw Manager: Drawing Composition


Production drawings will be generated based on Template
Drawings.


These templates indicate what and where the RM Bridge
drawings will be placed into the sheets.
