Space Elastic Frame Analysis with Linear Static Applications (update:08-09-07)

Space elastic-frame systems

Description:

Space elastic-frames systems has finite element applications are very significant for more civil engineer of areas. Also, in this areas of more books had wrote with general theory, application and methods. I perused more books and all books are not intelligible for space-frame transformation or conversion matrix components.

In this matlab sub-program had perused space-frame system analyis with linear static model. Especially, in sub-functions had compared general and special transformation matrix as axial-rotation matrix (beta-transform).

I wish, this works will be usefully for more researcher by this reason.

Example:
[Pg,Pl,Hu] = space_frame
