bridge analysis
(OP)
Hi
I am busy with the design of concrete bridge. the length is 24m and the bridge is divided in four(4) equal span of 6m. At the internal support I have expansion joints. My question is how to analyse the bridge. My approach was to analyse it as a single span of 6m because the expansion on the support will give me zero moment and because of the expansion joint at the internal support I did not think to analysis it as a continuous beam ( 4 span of 6m each) because that will give me a sagging and hogging moment. Can someone help on that.

Is this a student project?

There is a free program developed by WSDOT and TX Dot called PGSuper.
That is used for design bridges.Not sure what kind of superstructure you have though.

I suggest you get a consultant to guide you, it is too much to run it by this forums.
Good Luck

Help the guy out if you can that's what this forum is for. Advising him to go to a consultant because it is complicated maybe one answer, but if that were the answer for all the posts in this forum, it would cease to exist!

JedClampett summed it up well: "If you're designing a 24 meter long bridge and need this clarified, it scares me. "

Complicated drainage systems are almost as bad. I once spotted a drain pipe with 11 (Yes, ELEVEN!) 90-degree elbows. No wonder it was full of debris and didn't actually drain any water.
