A file `Cbeam.ini' keeps information of the location of
the main window, language setting and sign convention of
the moment diagram explained in Sec..
This file is read when this program is executed
and is revised when it is stopped.
If you accidentally erase this file, by NotePad or
an editor you must make a file named `Cbeam.ini' containing
four lines as
in the directory where `Cbeam.exe' exists. The first two data are coordinates of the main window. The third data represents language selection, and![]()
Every time of analyses; i.e. at every double-click in the Results Window, six files are created in the directory where `Cbeam.exe' exists.
[l] CntBeam.dat: Simple data (text file)These files can be used to draw figure from results, or can be input to this program `Cbeam.exe' as a setting data. All of these files are over-written every time FEM analysis is carried out. Therefore, if you want to use some of these files afterwards, you must move necessary files to a different directory or you must rename them properly.
Cbeam-d.tex, Cbeam-r.tex, Cbeam-s.tex, Cbeam-m.tex,: Picture files for LATEX
Cbeam.cbm: Setting file for this particular program
A data file `CntBeam.dat' contains lines of numerical data of settings and results. For example, the lines of results look like
% Results % Elmnt Node w/L w' SL^2/EI ML/EI 1 1 0 0 5.417556 -11.63432 1 2 24.57116 44.62769 5.417556 -6.21676 2 2 24.57116 44.62769 5.417556 -6.21676 .......and are simply lists of calculated results. At the beginning of this file, information about the boundary conditions, rigidities and loading conditions is also given.
Since many drawing software can handle such a file of data
separated by spaces as an input data,
this file can be used to draw, say, moment diagrams by some software.
As an example, a display by a freeware of
Ngraph
is shown in Fig..
Four output files are distinguished by a letter following a hyphen as
[l] d: Conditions and deflectionand contain expressions of figures in the picture environment of LATEX. However, since some `
r: Bending rigidity ratio
s: Shear diagram
m: Moment diagram
\special
's of EPIC code
are used, you must need two style files as
`epic.sty' and `eepic.sty.'
The latter can be replaced by another version of
the similar style files, `ecleepic.sty.'
A file `Cbeam209.tex' in the archive is an example source
file in LATEX209, while `Cbeam-2e.tex' is for LATEX2e to
typeset such diagrams.
After an analysis of a certain beam, please compile one of these files.
Then the diagram figures as is shown in Fig.
can be obtained.
As you may see several numerals in the right figure of Fig.,
numerical results of some quantities are also output
in these LATEX files.
These lines can be found to be
% string \CbeaM(200,1500){{\tiny $-12.345$}}%in such files. If these output are not necessary, the lines starting by a command
\CbeaM
must be commented out or removed.
You can find a tip of handling this command
in the example files `Cbeam209.tex' and `Cbeam-2e.tex.'
Or replacing \CbeaM
by \path
yields output of such values.
If you need a neat output, you must adjust coordinates
manually one-by-one.
Otherwise such numerals sometimes lie upon lines of the diagram
as is seen in Fig.(200,1500)
in the above example.
The number at the left (200) is a horizontal coordinate
positive to the right direction,
while right one (1500) is a vertical one positive to the upward direction.
It should be noted that the values of loads
shown in the deflection diagram are non-dimensionalized
as has been explained in Sec.; i.e. the values of
,
and
are
shown.
Also the part above the line showing
% BC's and others above this line. Deflection below this line.includes only the settings of BC's and beam itself, and lines below this line express deflection curve. Therefore, if you process lines above this particular comment, you can get a figure of the beam structure with BC's.
A file with extension `cbm,' for example
`Cbeam.cbm,' can be directly input by this program
as a basic data file of boundary and loading conditions.
The method will be explained in Sec..
Such a file is always output by this program after each FEM analysis.
