How do I save the graphic to my documentation (or print it)?

The following steps describes how to save Window's graphic to a documentation.   They are basic Window operations.

  1. Save your graphic to Windows' clipboard.  You may save the whole screen image to the clipboard by pressing the 'Print Screen' button of your keyboard.  If you simply want to save a specific window (of many opened Windows on your screen), position the cursor inside the target Window, press and hold the 'Alt' key, and press the 'Print Screen' key.  Now, only the image of that Window is saved to the clipboard.
  2. Paste the saved graphic onto your favorite text editor (or WinEd.exe).  Open (or Create) your documentation with your favorite text editor and click on the menu 'Edit' - 'Paste' to paste the clipboard's image to your documentation.  That's all.

Once the graphic is on your documentation, it can be resized, repositioned, or printed.

Window's clipboard is a holding place for all the saved items.  You can view the contents of the clipboard if you use the Clipboard Viewer ( Start - Programs - Accessories ) program.  In most case, you don't need to view the contents of the Window's clipboard.  Once the graphic is saved to the clipboard, it can be pasted to almost any text editor.

Again, follwoing is the step by step description:

  1. Bring up the desired graphic on screen.
  2. Save the image of the whole screen or a specific Window to Window's clipboard. (see the above step).
  3. Open (or create a new) documentation file,  position the cursor, and click on the 'Edit' - 'Paste' to paste the graphic.

How do I make the moment and shear diagram of my frame?

Following is the steps:

  • Make a model, define the load and solve the problem.
  • Use the Post Design option to select member(s) and load cases to plot the moment and shear diagram
  • After the moment and shear diagram is displayed, you may interactively code check and size the member.

In addition to the interactive code check and sizing of the members illustrated here, you can also batch code check and sizing the members by using DESIGN command of WinSTRUDL.

For example, let's use the demo1 problem (the input file is included in your WinSTRUDL subdirectory). 
The roof beams are numbered 11, 12, 13, and 14.  Whereas, the columns are numbered 1,2,3,4, and 5.  Here is the plot of the model.  Three load cases are defined for this problem: deadload, windload, and a load combination.  They are labeled as load cases 1, 2, and 3.

Run WinMaster.exe and load the 'File' demo1.  Click on the 'Run' button to ask for a solution, then click on the 'View Result' button to view the result.  Once the result file is generated, the information for moment and shear diagram is also saved.   Next, click  the 'Post Design' button.

wpe9.gif (11741 bytes)

This is the dialog box capable of generating enveloped shear and moment diagram for you.  In our case, let's ask for a shear and moment diagram of roof beams.  The roof beams consist of members 11, 12, 13, and 14.  So, specify these four members in he Edit box next to 'Member Selected' label.  For load cases, let ask for the enveloped moment and shear diagram of load cases 1, and 2.  So, specify 1,2 in the edit box next to the label 'Load Select'.  Note that, you may use either space or comma to separate the numbers.  If only one load case is selected, then, the moment and shear diagram will be the moment and shear diagram of that load case alone.  If you specify more than one load case, the enveloped moment and shear diagram will then be presented.
Click 'OK'.

Following is the enveloped moment and shear diagram for roof members.  If this is a 3D problem, the first moment and shear diagram is the major moment and its corresponding shear diagram.  You may click on the 'Minor' menu to switch to the minor bending moment and its corresponding shear diagram.

There is another way to define the roof members. It is called the 'Continuous member' definition.  Instead of specifying '11,12,13,14', you may say '11 continuous', or '11 con', or '12 con'.  Either way, WinSTRUDL will select all the members connected to member 11 (or 12) and group them automatically.  Following is the example of specifying '11 con' instead of '11, 12, 13, 14'.  Click on the 'OK' button and you will find that it yields the same picture as above.

wpe4.gif (11866 bytes)

In addition to the 'Continuous member' select, WinSTRUDL is capable of doing 'similar member' selection.  In our example, columns are numbered 1, 2, 3, 4, 5.  Instead of being continuos, we have similar members and we want to perform a typical design for all the columns.  In this case, we simply specify '1;2;3;4;5' using ';'  to separate the members.  When WinSTRUDL sees ';' is used to separate members, it will treat members between ';' as similar members.  WinSTRUDL will then generate a shear and moment diagram that envelopes all of the members.  Following is the example.

The enveloped moment and shear diagram for all columns of the two load cases is shown below:

Finally, the continuous member and similar member specification can be combined.   Use it wisely, you may design hundreds of members in one command.

How do I control my output unit in WinSTRUDL?

In WinSTRUDL, You may use the UNIT command to control the input/output units.   There are two ways of specifying the unit command.  The first one is to control the unit globally and the second one is to control the unit locally.

Global UNIT:  If the UNIT command is the only command included in that line of input and is specified within the first three columns, it is a global UNIT command. A global UNIT command changes the active units to the specified units until the next global unit command is encountered.  Any information defined thereafter will carry the active global units except the input effected by the Local UNIT command (see below).

Local UNIT:  If the UNIT command is specified with other information and is specified beyond the first three (3) columns, it is called a local UNIT command. A local UNIT command temporally switches the unit of the problem to the specified local units only for that particular line of input. When the next input line is read, the  units will switch back to the active global units. NOTE: Unlike the global UNIT command, the local UNIT command must be spelled out (four (4) characters).

For example, (Information after the '$' sign is comment)

TYPE PLAN FRAME     $ This is a 2D frame problem
$ first define the Global UNIT is FT
UNIT FT            
JOINT COORDINATE        $ Start joint coordinates     
1 10 0                                    $ X coor. of joint 1 is 10 ft.    
$ next line uses Local UNIT;  X coor. of joint 2 is 240 inches.
2 240 0 UNIT INCH        
$ Back to global UNIT again, X coor. of joint 21 is 30 ft.
21 30 0            
22 1000 0 UNIT CM     $ X of joint 22 is 1000 cm, Local UNIT
UNIT IN            $ Global UNIT now is in inches
31 500 0             $ X of joint 31 is 500 inches
......
......
......
.....
$  next line uses Local UNIT;   stress output is in ksi
LIST MEMBER STRESS ALL UNIT KIP INCH   
......
$  next line uses Local UNIT;   force output is in kip-ft
LIST MEMBER FORCE ALL UNIT KIP FT   
$ Switches global unit to mm
UNIT mm                  $ Global unit now is in mm
$ The displacement output is in mm
LIST JOINT DISPLACEMENT ALL

How do I supprss the header or control the line per page on my WinSTRUDL or WinBeam report?

WinStrudl:You may use the 'OUTPUT' command to control the format of the output. If you specify 'OUTPUT logo off' at the top of your input, all of your output will be suppressed without page break and header.

If you want to keep the header and the page break, use the 'OUTPUT lpg' command. For example, if you have a printer that prints 80 lines per page, you need to specify 'OUTPUT lpg 80' at the top of the input so that WinSTRUDL knows every 80 lines of output a page break need to be inserted. The defaulted lpg is 55

WinBeam: The defaulted lpg is 55. If you want to change it, create a file entitled 'WinEd.DEF' in your WSTRUDL subdirectory, use a text editor to create a line that defines the number of lines per page for your printer. The command is "3DLPG=???". For example, if you have a printer that prints 90 lines per page, specify 3DLPG=90 in the file WinEd.DEF.
