Mass to Load

Scripts on this page are available here:

MassToLoad.js

This example shows how to convert convert mass to load

The enclosed js-file mass_to_load.js gives an example on how the mass of a named set can generate a loadcase consisting of constant pressure (from the mass of a plate), constant line load (from the mass of a beam) and point load (from a point mass).

The loads are based on an acceleration vector defined by the user - the enclosed example uses vertical acceleration -9.81 m/sec**2, but you can also include the horizontal components.

To test out this functionality:

  • Make a model in GeniE

  • Make 3 different named sets and call them Nset1, Nset2 and Nset3.

  • Make sure that you have both beams, plates and point masses in some of the sets

  • Read in the js-file MassToLoad.js

  • There are now 3 new loadcases called LC_Mass_Nset1, LC_Mass_Nset2, LC_Mass_Nset3

This utility js-file works for planar geometry. The pictures below shows three different sets and the new loadcases as generated when importing the above js-file.
