Generating RC column design cases with API - problem with reinforcement def.

[Anonymous]

Hi All,

I am trying to automatically generate column elements in RC design module. The internal forces have been calculated by other software, this time I am keen to use Robot for automated column rebar verification and report generation. Currently I am using the latest Robot available in company - 2016. However, I can downgrade if that helps.

I read this post: http://forums.autodesk.com/t5/forums/forumtopicprintpage/board-id/351/message-id/25090/print-single-...

It is kind-of what I want to do, I just feel that using ROBarShapeDb library may be an overkill if I only want to let Robot know my straight longitudinal bars and transverse rebar. Only thing I need is calculation note - no need for fancy detailing.

So below is my C# code. I am just trying to add one longitudinal bar just to test it.

I don't receive any error, but neither the bar appear. My job preferences are set to BS bar shapes, thus "00" should work as straight bar.

What am I doing wrong?

             iapp.Visible = 1;
            iapp.Interactive = 0;
            //iapp.Project.Open(Filename);
            iapp.Project.New(IRobotProjectType.I_PT_CONCRETE_COLUMN);

           
             ColumnComponent = iapp.Project.ComponentMngr.Create(IRobotProjectComponentType.I_PCT_COLUMN, "supercolumn", "1");
             RCcolumn = ColumnComponent.Data;

            //geometry
             RCcolumn.Geometry.Section = IRConcrColumnSectionType.I_CCT_COLUMN_SEC_R;
             RCcolumn.Geometry.set_Dim(IRConcrColumnDimensionType.I_CCD_COLUMN_DIM_A, 1); // b=
             RCcolumn.Geometry.set_Dim(IRConcrColumnDimensionType.I_CCD_COLUMN_DIM_B, 0.25); // h=
             RCcolumn.Geometry.set_Dim(IRConcrColumnDimensionType.I_CCD_COLUMN_DIM_EPD, 0.2); // hs= , slab thickness
             RCcolumn.Geometry.set_Dim(IRConcrColumnDimensionType.I_CCD_COLUMN_DIM_HSD, 2.85); // =h.c-h.s             
             RCcolumn.Geometry.set_Dim(IRConcrColumnDimensionType.I_CCD_COLUMN_DIM_HSP, 2.85); // =h.c-h.b            
             RCcolumn.Geometry.set_Dim(IRConcrColumnDimensionType.I_CCD_COLUMN_DIM_HSP_X, 2.85); // =h.c-h.b one direction            
            RCcolumn.Geometry.set_Dim(IRConcrColumnDimensionType.I_CCD_COLUMN_DIM_HSP_Y, 2.85); // =h.c-h.b second direction

            //materials
            RCcolumn.Concrete.CharacteristicStrength = 40000000;

            //cover
            double cover = 0.05;
            RCcolumn.CalculationOptions.Cover = cover;
            
            //loads
            IRConcrColumnLoad columnLoads = RCcolumn.Loads.Add();
            columnLoads.CaseName = "firstCase";
            columnLoads.CaseType = IRConcrColumnLoadCaseType.I_RCL_LOAD_CASE_DESIGN_ACC;
            columnLoads.N = 4000000;

            //rebar
            double diameterLong = 0.032;
            IRConcrReinforcingBar bar = RCcolumn.Reinforcement.Bars.Add("00", IRConcrBarType.I_CBT_BAR_TYPE_LON_MAIN, IRConcrBarSubtype.I_CBS_BAR_SUBTYPE_DOWN, diameterLong);
            
            
            bar.SteelType = IRConcrSteelType.I_CST_STEEL_TYPE_LONG;
            bar.SetDirections(0, 0, 0, -1, 0, 0);
           bar.Position.X = 0.05;
           bar.Position.Y = 0.05;
           bar.Position.Z = 0.05;
           


            //buckling parameters
            RCcolumn.BucklingModel.IsSwayY = false;
            RCcolumn.BucklingModel.IsSwayZ = false;
            RCcolumn.BucklingModel.IsDirectionYOff = true;
            RCcolumn.BucklingModel.IsDirectionZOff = true;
            RCcolumn.BucklingModel.KY = 0.85;
            RCcolumn.BucklingModel.KZ = 0.85;

            RCcolumn.Save();


            iapp.Interactive = 1;

I have personally never played with reinforcement by API but as far as got to know your code will not work.
Rebars must be defined by RoBarShape

Rafal,

Thanks for update. I'll let you know the progress - hopefully I will manage to do this with RoBarShape.

I just returned to solving this problem. And realized that RoBarShape library seems not to be included in default Robot 2016 installation.. Where is it hiding?
