  • Can grid lines be imported from Auto-cad?
    • Grids cannot be imported from Auto-cad. For Staad files RCDC auto identifies the grids as per centre of columns and for E-tabs it reads if they are available. User can view or edit the grids label and location. For more information refer topic “Grid Lines” from help Content.

  • Can all design calculation reports exported in Excel format?
    • Design reports are generated in platform independent html format so as to facilitate the user to open it in any software. User can open the HTML File in excel and word.

  • How to freeze drawing style settings in all newly opened RCDC file?
    • Before starting project, settings for drawings style can be modify/update for all element. Please refer help for more details.

  • The load combinations considered for regular/irregular building in sizing are with factor 1 for all load cases. Can this factor be an input?
    • Factor can’t be an input, as for sizing of footing/Pile-cap different factors are to be considered for dead, live and other load cases. However, user can create his own load combination templates by using ‘Add Load Combination’ option and creating a new template. User also can add or remove load combinations as per requirements. For more information refer Topic “Load and Load combinations” from help Content.

  • While trying to design RCC beam using ACI 318, exporting the data from ETABS in FPS (foot-pound-second) system, but the data that is being reflected in RCDC is in MKS (meter-kilogram-second) system.
    • RCDC refers to ACI-318M-2011 (metric units) code. If data is exported in feet and inches RCDC internally changes the forces in to kN and m. Working environment in RCDC is in MKS units. User can provide the input data in kN and M unit for RCDC. The output can be generated in inches unit. Refer ‘Style Manager’ in RCDC for the same.

  • Is the Vertical axis of STAAD and RCDC Same?

    At the time of importing the loads in RCDC if we give X direction to Earthquake X and Z direction to earthquake Z, then it will convert it in its relevant direction?

    • RCDC is a design software and imports the analysis forces from STAAD for design. There is no specific axis of the RCDC.

      example: for column design, RCDC get the forces along major and minor axis. whatever the load cases defined in analysis, RCDC get the forces for local member and it designs the member. 

      Defining direction for Eq forces i.e. X and Z, it just a load case type. it will just help to create load combinations as per load type. if Eq-z is available in Analysis and it is defined as Eq-Y then it doesn't affect the design forces of the member. Forces for that load case will remains same. EQ-Y is just a nomenclature for that load case.
