Optimization Method vs Trial and Error Method:
Many
panel lifting designers have painful experience of playing around insert
locations to lower the Maximum Bending Moment. It could take you
half a day, howerver the result is not the best one yet. Here comes the
breakthrough technological innovation. When using the optimization
feature in TiltMAX, you can obtain the lowest Maximum Bending Moment
just in seconds.
Let's try some examples. (Panel1, Panel2 and Panel3)

Trial and Error Method
Fig 2 describes different insert locations between using Optimization function of TiltMAX and using traditional trial and error method. (Green color represents Optimization result, red color represents trial and error method result.) We should notice that the Maximum Bending Moment is very sensitive to the insert locations. Guessing from experience is far from enough.

- M represents Maximum bending moment
- Time means how long it takes to get the results
The above table compares the results of two ways in panel lifting sequence: Maximum Bending Moment and engineers working hours. From the table, you can see TiltMAX not only saves designers working hours but also and most importantly save more than 30% of the building materials.
BendingMoment Optimization vs Stress Optimization:
|
When
panel shapes become more and more complex, we introduce a function
call Stress Optimization. when you use Stress Optimization,
the program try to distribute the bending moment according to out
of plan stiffness of the panel, therefore reduce the necessary of
placing extra reinforcement in the panel. Here
are some analyze
results using BendingMoment
Optimization and Stress
Optimization respectively. The panel shape
and dimension shown on the right. (Click the text in blue to view
individual diagrams.) As you can see from the results, although the Bending Moment Optimization gives you the lowest maximun bending moment, but it introduces a higher maximum bendingmoment at the section of the circle window area. Thus you have to place extra reinforcement into this section. On the other hand, the result of the Stress Optimization gives you a little bit higher maximum bendingmoment, however its maxi bendingmoment at the section of the circle window is lower, so you do not have to place extra reinforcement into this section. In other words, it will save you material and money. |
