Code Check Results
Click on the Tiling button, select Member Steel Results and click OK.
The first things you will notice are the red members in the model view indicating
that we have members that are failing.
Notice that the spreadsheet results are now reporting the “worst case” results as a
result of the envelope solution we ran. The columns labeled “lc” report the load
combination that generated the controlling values. Other results not shown here
such as the member forces display Maximum and Minimum results in order to
capture the worst of both negative and positive results. When you perform an
envelope solution the spreadsheet results will contain this additional information.
Optimizing Member Sizes
The fourth spreadsheet from the top reports what RISA-3D is suggesting for
alternate shape sizes along with the member that is controlling the design.
On this spreadsheet RISA-3D suggests an alternative shape for each section set or
member. If we are already using the optimum shape for a section set or member,
then it will not be listed on this spreadsheet.
Note that if you have modified your design lists by adding or removing shapes
RISA-3D may pick different shapes than are shown here.
Click on the Suggest Shapes spreadsheet to make it active. The Window
Toolbar presents the Replace and Resolve button. Click this button and
agree to resolve by clicking Yes.
Now only a couple of members are in trouble. Let’s look at another way to
substitute suggested shapes.
Press Ctrl-Alt-F7 to substitute the shapes and resolve the model.
All of our members should now be optimized.
Excluding Results
We will use the Wood Code Checks spreadsheet to sort the members and then
hide results for members that have a code check value lower than “0.6”.
Click on the Tiling button, select Member Wood Results and click OK.
Make Envelope NDS Wood Code Checks the active window by clicking on it.
Stretch the bottom of the window down so that you can view more of the results.
