Replication of Analysis in Bridge Designer
In order to make sure results of the hand
analysis correspond to online Bridge Designer I use every square as a two time
two square. The length of the bridge is 36’’. That meant that I use 18 little squares
as my base and my high is 10’’. That made my bridge has 5 squares high. So my
hand analysis has same angle as the online bridge. Same angle is very important
in the calculation. That make sure I have a correct number in my online bridge
designer. The online bridge designer also is a tool to make sure my calculation
is right. My number of calculation is mostly match to the online one, so my
calculation should be right.
We change our bridge a lot to follow the
ruler of member add 3 equal twice the nodes. The online Bridge Designer cans
only calculation particular member and nodes. That made the calculation it give
did not match the number the number we get in the text. But I try my best to
get it as close as possible. I put 35 pounds load on the bridge. It should that
some member get a lot of forces in other hand some member did not get any of
the force. I do not know is that number come out because my changer of the
structure or our bridge have this problem in the first time. However get to
know force on each member is very helpful in future design. We can improve our
design and made it became more effective by that way. Such as cut up the member
in the place that have less force or do not have force at all. Add more members
to the place, which has a lot of force. In the picture shows that middle has a
lot of force. We may add some member in the middle. The online bridge design
was very helpful. I hop we can made a better bridge next time.
