Bridge Designer III (BD3) by Interactive Design Systems

3.82 - What's this?

BD3 is a design & Analyis Package For Bridge Design Engineers and Consultants. BD3 is essentially a 3D version of Bridge Designer. In BD3 the members are 6 degree of freedom beams and the displacement field is 3-dimensional (3 translations and 3 rotations)

Features

  • » Results are provided by BD3 in a 3-dimensional displacement field. Therefore there are 6 degrees of freedom per node (as opposed to 3 degrees of freedom in BD2).
  • » The stiffness matrix of each element is a 144-term matrix (as opposed to 36 terms in 2D). Even with bandwidth optimization the overall stiffness matrix is much larger, and so are all the components needed in the analysis. Therefore, BD3 uses more memory than BD2.
  • » Because of the 6 degrees of freedom, the internal forces resulting form the 3D analysis which now has 6 components, 3 force components (Fx, Fy and Fz), and 3 bending moments (Mx, My and Mz). These forces are produced for all the active members, for all load-cases and all construction phases. There is therefore a large amount of information produced, and this encourages the use of a graphical environment to view results.
  • » In order to be meaningful, results are shown either in local or general systems. For example it is appropriate to show the Mx moment (torsion) expressed in local.
  • » Supports and Restraints may be defined in local systems as well as in the general system, as dictated by the bridge model (horizontal and vertical curvature).
  • » Post-Tensioning tendons are defined in 3D as they are in BD2 as well. However, in BD3 there is a difference between “internal” and “external” tendons. Because of the overall model geometry (for example horizontal curvature), “external” tendons are assumed linear between deviation points (anchors and deviation blocks), and “internal” tendons, being inside the concrete elements, follow the overall model curvature.
