Users can build up beam sections using common shapes (rectangles, triangles, angle sections, channel sections, etc).
Sections are constructed using shapes and even other sections.
Tree View Visualization of Section Build up
Users define materials, and then assign them to a shape prior to building up a section. The following properties can be defined:
- E: Modulus of Elasticity
- G: Shear Modulus
- v: Poisson's ratio
- MaterialColor_Hex: color for all shapes composed of this color (defined in HEX)
Currently, only isotropic materials can be used. Orthotropic materials have been explored, but haven't been fully implemented yet.
Example:
IsoMaterial mat = new IsoMaterial { Name = "mat1", E = 1, G = 1, v = 0.33, MaterialColor_Hex = "#00FF00" };
Positioning: Position shapes by defining a point (specific to each shape type, shown below) and it's location coordinates, xp and yp.
Dimensions: Each shape has a unique set of dimensions that can be defined.
Rotation: Rotate shapes using the ".theta" property
Mirroring: Mirror shapes using the ".mirrorX" and ".mirrorY" properties
Example:
SectionElements.MachinedAngle MA = new SectionElements.MachinedAngle();
MA.b1 = 4;
MA.b2 = 5;
MA.t1 = 0.50;
MA.t2 = 0.50;
MA.r = 0.50;
MA.theta = 30 * Math.PI / 180;
MA.point = "a";
MA.xp = 1.6824;
MA.yp = -0.1334;
MA.Material = mat;
MA.mirrorY = true;
Add shapes to section:
Section sec = new Section();
sec.AddShape(MA);
Calculate Section Properties (EA, EIxx, EIyy, EIxy, Xcg, Ycg, etc)
SecProp sp = sec.CalculateSecProp();
Draw Section to file:
EnvelopeCoords env = sec.GetEnvelopeCoord(); //GetEnvelopeCoords will find the x and y min and max of the section (for plotting purposes)
Bitmap bitmap = new Bitmap(1000, 1000);
PlotProperties pp = env.GetPlotProperties(1); //adds padding to envelope from above
sec.Draw(ref bitmap, pp);
bitmap.Save("Shape2.bmp");
IsoMaterial mat = new IsoMaterial { Name = "mat1", E = 1, G = 1, v = 0.33, MaterialColor_Hex = "#00FF00" };
SectionElements.MachinedAngle MA = new SectionElements.MachinedAngle();
MA.b1 = 4;
MA.b2 = 5;
MA.t1 = 0.50;
MA.t2 = 0.50;
MA.r = 0.50;
MA.theta = 30 * Math.PI / 180;
MA.point = "a";
MA.xp = 1.6824;
MA.yp = -0.1334;
MA.Material = mat;
MA.mirrorY = true;
SectionElements.Rectangle rec = new SectionElements.Rectangle();
rec.b = 6;
rec.t = 0.375;
rec.point = "g";
rec.xp = 2.7359;
rec.yp = 0.0369;
rec.theta = MA.theta;
rec.Material = mat;
Section sec = new Section();
sec.AddShape(MA);
sec.AddShape(rec);
SecProp sp = sec.CalculateSecProp();
EnvelopeCoords env = sec.GetEnvelopeCoord();
Bitmap bitmap = new Bitmap(1000, 1000);
PlotProperties pp = env.GetPlotProperties(1);
sec.Draw(ref bitmap, pp);
bitmap.Save("Shape2.bmp");
sec.Draw(...) output
