An example is presented to illustrate the way Advance Design exports geometrical and loading data to Advance BIM Designers Footing. The model consists of a reinforced concrete column resting on a fixed rigid point support, as in the image below. Loads are expressed relative to the column local axes.
Column properties in Advance Design
The Footing dimensions are established in the point support Properties list in accordance with the local axes of the column.
Definition of footing dimensions
a – is the width of the foundation block (footing); it is considered along the y local axis of the column above.
b – is the length of the foundation block (footing); it is considered along the z local axis of the column above.
h – is the height of the foundation block (footing); it is considered along the x local axis of the column above.
After the FEM (finite element method) calculation, the footing is exported to Advance BIM Designers Footing.
- Imported column properties:
When exported from Advance Design to BIM Designers, the column dimensions are transferred as follows:
The dimension along y local axis in Advance Design (width in this example) is represented in BIM Designers on the x axis and is defined as “Width (a)”
The dimension along z local axis in Advance Design (length in this example) is represented in BIM Designers on the y axis and is defined as “Length (b)”
The dimension along x local axis in Advance Design (height in this example) is represented in BIM Designers on the z axis and is defined as “Height (h)”
Column properties imported in BIM Designers
- Imported footing properties:
When exported from Advance Design to BIM Designers, the footing dimensions are transferred as follows, where:
The dimension along y local axis in Advance Design (width in this example) is represented in BIM Designers on the x axis and is defined as “Width (A)”
The dimension along z local axis in Advance Design (length in this example) is represented in BIM Designers on the y axis and is defined as “Length (B)”
The dimension along x local axis in Advance Design (height in this example) is represented in BIM Designers on the z axis and is defined as “Height (H)”
Footing properties imported in BIM Designers
The geometry of the footing is transferred from Advance Design to BIM Designers in accord with local axes directions of the column above it.
- Loads from load cases transferred to BIM Designers:
The forces acting on the foundation are produced by the column and Advance Design displays them according to the linear elements conventions (see “Linear and planar elements conventions” section in Help). When transferred, they are converted to follow the BIM Designers convention.
BIM Designers convention and converted forces
V – is the axial force acting on the foundation (compression from the column, Fx, is taken with positive sign)
Hx – is the horizontal force acting on the foundation block on the x direction. In Advance Design, this is the shear force acting on the y local direction of the column, Fy
Hy – is the horizontal force acting on the foundation block on the x direction. In Advance Design, this is the shear force acting on the z local direction of the column, Fz
Mx – is the bending moment about de x footing axis produced by Hy
My – is the bending moment about de y footing axis produced by Hx
Conversion of Forces from Advance Design in accordance with the BIM Designers convention
The loads are transferred from Advance Design and adjusted to the BIM Designers convention and axes, keeping the global effect on the foundation.
