1. Static Calculation: usual structural analysis

For RM Bridge inside OpenBridge Designer, at AnalyzerAnalyzer/Schedule/Stages/Schedule Actions/Static Calculation the users will find the available standard static structural analysis:

Calc: Calculate static load
Stress: Calculate internal primary forces of tendons by stepwise applying the tensioning actions defined in a stress label.

As next step in prestressing calculation the actual prestressing load case is calculated ( ++Calc action with a load case of type TEND0)
ducts of internal tendons are grouted as final step ( action ++Grout )
Action > GroutGrout ducts of internal tendons and establish composite cross-sections by adhesion (calculation options set in the .: Recalc - pad apply).Action: TStopThis action is used to ‘freeze’ creep, shrinkage and relaxation for given elements. This may simplify modeling of structures with a number of similar independent stages, such as balanced cantilever bridges built from two ore more piers.Action: Creep (static calculation)Creep, Shrinkage and Relaxation calculation. Results are stored to a given (empty) load case.Action: UpdEmodTemporarily update the young’s modulus for all materials with an Emod(t) definition. An existing given load case is calculated with the modified young’s modulus and the differential results are written to the output load case.Action: CabSagManual definition of virtual young's moduli (Ernst-Moduli E*) for individual cables to take non linearity due to sagging into account. Definition of multiplication factors.

Construction Schedule .: Stage Actions : Static Calculation

Available actions for static structural analysis are:


Action > Infl	Calculate influence lines for given traffic lanes.
Action: LiveSet	Influence line evaluation for non-linear analysis. A load train position is calculated according to the influence line for the given structure point. The result is a load arrangement of the load train stored into a load set.
Action > LiveL	Influence line evaluation of a load train moving along a lane. The influence line has to be calculated from lane definitions with the action ++Infl before.
Action > TempVar	Process temperature points (collected by an attribute set) for non-linear temperature loading. A load set is created with this action that represents the temperature load (temperature loading according to AASHTO and BS)
Action > Buckle	Calculation of buckling eigenmodes and buckling factors for a reference load case.
Action: Failure	Increase the loadfactor in a given range until buckling of the structure occurs (full geometrically non-linear analysis ).
Action > ReloadLc/ReloadSup	Cracked concrete - Reload considering cracked tension zones. The internal forces of the given load case are redistributed in the cross sections planes for cracked tension zones.
Action > ReloadLc/ReloadSup	Cracked concrete - Reload considering cracked tension zones. The internal forces of the given superposition file are redistributed in the cross sections planes for cracked tension zones.
Action > OpenTcl	Open and run a TCL module from the TCL-Script library.
Action: RunTcl	Run an existing TCL-script file.
Action > Restart	Calculates the new constant load case factors for variable load cases from AddConstraints
Action > Store	Store the calculation for later restart at the label
Action > PushOver	Non-linear calculation action using a load-stepping procedure
