  3. 3. 3 / 12 Civil 2014 V2.1 Release NoteCivil 2014 Enhancement Load tab > Moving Load > Moving Load Code > Eurocode  Results > Moving Load > Moving Tracer 1.Improvementsin EurocodeMovingLoadAnalysis 1.1 Centrifugal Forces  Centrifugal force due to vehicle load in the horizontally curved bridge can be generated as a static load from the Moving Load Tracer.  Following vehicle types are supported with “Traffic Line Lane”.Traffic Surface Lane is not supported.  Road Bridge:Load Model 1 Standard and user-defined vehicle  Railway Bridge:Standard Vehicle – LM71, SW/0, SW/2, Unloaded Train,HSLM User Defined Vehicle – LM71,SW/0, SW/2, Unloaded Train  Characteristic value of centrifugal forces are automatically calculated as per EN1991-2:2003,clause 4.4.2 and 6.5.1. RoadBridge Railway Bridge
  4. 4. 4 / 12 Civil 2014 V2.1 Release NoteCivil 2014 Enhancement 1.2 Eccentricity of Vertical Loads of Rail Traffics  The effectof lateral displacementof vertical loads can be considered in Standard and User-defined vehicle dialog box.  Eccentricity of vertical load to consider cantcan be defined in Traffic Line Lane dialog box.  Eccentricity needs to be calculated by the user according to the code provision. Eccentricity of lateral displacement of vertical loads Load tab > Moving Load > Moving Load Code > Eurocode Load tab > Moving Load > Moving Load Analysis Data > Vehicles > Add Standard/User Defined > EN1991-2:2003 – Rail Traffic Load Eccentricity to consider cant
  5. 5. 5 / 12 Civil 2014 V2.1 Release NoteCivil 2014 Enhancement 1.3 Concurrent Stresses  Concurrentstresses of frame elements due to traffic loads are provided as well as concurrentforces. Concurrent stress option Load tab > Moving Load > Moving Load Code > Eurocode Results tab > Results Tables > Beam > Stress Beam Stress Table Concurrent Stress Table
  6. 6. 6 / 12 Civil 2014 V2.1 Release NoteCivil 2014 Enhancement 1.4 User-defined Railway Traffic Loads  The user-defined traffic loads can be used to consider differentNational Annex by countries.In the previous version of midas Civil,only standard vehicles were applicable. Load Model 71 SW/0 HSLM A  Load tab > Moving Load > Moving Load Code > Eurocode  Load tab > Moving Load > Vehicles > User Defined
  7. 7. 7 / 12 Civil 2014 V2.1 Release NoteCivil 2014 Enhancement 1.5 User-defined Permit Truck Loads  The user-defined permittruck can be used to simulate special vehicle loads with any wheel arrangementand any amountof wheel loads. Permit Truck  Load tab > Moving Load > Moving Load Code > Eurocode  Load tab > Moving Load > Vehicles > User Defined
  8. 8. 8 / 12 Civil 2014 V2.1 Release NoteCivil 2014 Enhancement 1.6 Concurrent Reactions  The user can check the concurrentreaction data in a table format for the moving load analysis. Concurrent Reaction Group Concurrent Reaction Table  Load tab > Moving Load > Concurrent Reaction Group  Results tab > Results Tables > Concurrent(Max/Min) Table
  9. 9. 9 / 12 Civil 2014 V2.1 Release NoteCivil 2014 Enhancement 2.Simultaneousdisplayoftop and bottom stressdiagram – BridgeGirderDiagram  In the previous version,either top stress or bottom stress diagram can be displayed.Now,both stress diagram can be displayed at the same time in one graph.  Beam Forces/Moments can be displayed with various components atthe same time. Top and Bottom Combined Stress Diagram  Results tab > Bridge > Bridge Girder Diagram Bending Moment and Shear Force Diagram
  10. 10. 10 / 12 Civil 2014 V2.1 Release NoteCivil 2014 Enhancement Effective width scale factor – PCS box girder  Effective slab width is automatically calculated and considered in the calculation of bending stresses for both PSC box girder and composite steel plate girder.  Code reference:5.3.2.1 of EN 1992-2 for PSC box girder and 5.4.1.2 of EN 1994-2 for composite steel plate girder 3.Auto-calculation ofeffective slab width as per Eurocode Effective width scale factor – Composite steel plate girder  Structure tab > PSC Bridge > Effective Width  Structure tab > Composite Bridge > Effective Width
  11. 11. 11 / 12 Civil 2014 V2.1 Release NoteCivil 2014 Enhancement Buckling Mode Shape New geometry updated based on buckling mode shape Selecta buckling mode to revise the geometry of model. Geometric imperfection can easily be included in the analysis model. The buckling behavior of the model can be further investigated by performing geometric and material nonlinear analysis. 4.Update GeometryofAnalysis Modelusing Buckling Mode Shape  Create a new model file in which the geometry of analysis model is revised based on the mode shape of linear buckling analysis.  The new model can be used for further geometric and material nonlinear analysis to find a buckling load considering geometric imperfection.  The mode shape is scaled by the scale factor or by the maximum mode shape.The scaled mode shape is added to the nodal coordinates. Scale Factor Updated coordinate = (initial coordinate) + (mode shape) x (scale factor) Maximum Value Updated coordinate = (initial coordinate) + (mode shape) x (maximum value)/(maximum mode shape)  Results tab > Mode Shapes > Buckling Mode Shapes
  12. 12. 12 / 12 Civil 2014 V2.1 Release NoteCivil 2014 Enhancement  Strands/Tendons can be created using Tendon Template,which will enable the user to generate prestressed beams easily and quickly.  Auto-generation of the UK PSC section database is supported.  Straighttendons and harped tendons can be defined based on the span and section information. 5.Easyand FastGenerationofStrands/Tendons  Structure tab > Wizard > PSC Bridge > Tendon Template Tendon Template Add/Modify Tendon Template
