Help needed in modeling a horizontally curved bridge by STAAD.Pro2004
(OP)
I am trying to model a horizontally curved bridge by STAAD.Pro2004. How do i create this model?
I tried creating rectangular concrete beam and then analyze it.But I am not sure is this OK or not.So I need help.If any one can give me any worked out example it will be better.Then I can point out my mistakes.
Help is much appreciated.

If you have no such experienced advisors, you should not attempt such an analysis in STAAD but by using a more specific application such as MDX for steel bridges or CONSPAN by Bently or ADAPT for concrete bridges. At least with these packages you will get examples and expert technical support. Even then, it is avisable to have a senior engineer checking your work within your firm.

But please tell me an easy way to analyze a curved beam only by any available software.

1. ASCE Structural Engineering Journal
2. ASCE Bridge Engineering Journal
You will find articles in each that will demonstrate to some degree what is typically done to model curved bridges in FEA.
Even then I must warn you that there are many, many nuances, especially, in how to connect the various elements of the bridge together. This should be done by an experienced modeler preferably with bridge experience.

Why don't you try with something very simple. Then you can see if you get the same results from the software as you get "by hand". You have to make sure that you understand what the number from the software represents before you use them.
Good Luck

I have tried for straight beam both by hand and software,both give the same result.But I don't know how to do it when the beam is curved.

Don't you know how to calculate it "by hand" or don't you know how to create a curved beam in Staad.Pro?

I don't mean to be rude but if you can't check STAAD.Pro for a simple problem you probably should't use it for a "real" problem.
Good Luck
