I am trying to get some information on this curved girder bridge design/analysis program developed by Bridge Sortware Development International, Ltd. Somehow I couldn't find the company's website or any information related to their product. Does anyone have experience using this program before...
I used to use traditional ANSYS GUI to build, solve, and postprocess the results. Now I have Workbench and also DesignModeler installed on my computer. DesignModeler seems to be very fancy but I am not sure if it is easy to learn and whether or not it can replace the traditional GUI...

I am working on the design of a concrete integral pier cap for a two-span curved girder unit. The column is about 48' high and the overall roadway is 50' wide. My question is how to perform the column analysis? Some technical papers I read required full longitudinal frame analysis with girders...
Hi, there -
I once used the traditional GUI of ANSYS. How hard does it take to get familiar to the Workbench? I sat in a presentation about Workbench recently and it really looks like a very good product. But where do you start? The help menu does not seem to provide good tutorials as for the...
Thanks everyone for your help! I've contacted Dr. Fu as some of you suggested during the analysis of the bridge using Descus-I. He was very helpful and responded quickly for the questions I raised. That made me feel comfortable with the program. Overall, the program is very good, but you need to...
Thanks so much , cbrn! I never used Workbench before but I do have it loaded on my computer. I actually scheduled a Workbench demo at our office later this week. Hopefully those guys from ANSYS can give us a jump start on this new product. Also, MicroStation can export to IGES files too. We will...
We are trying to import the geometry of a steel bridge from MicroStation file into ANSYS. MicroStation is a CAD program like AutoCAD. It can export files in formats such as IGES, SAT, CGM ... The file format we selected is SAT. When imported into ANSYS, we got lines curved and areas not shown up...
Well, I've had LRFD bridge designs before but this is the first one with curved girder. You know the 2005 interim has combined both straight and curved girder designs into one unified code, which I really don't know if I should appreciate or not. It's my first curved girder design no matter what...
Thanks everyone for the input! I just got the newest version of DESCUS I on my computer now. Since this is also the first time I use this program, I have so many questions about it. The one I am having right now is the Live Load Distribution Factor. For example, if Girder 2 is the primary...
I am about to use DESCUS I to design a curved girder bridge with 2005 LRFD spec. Is the program able to handle the new code? Thanks ahead for any input!
Thanks WillisV! I never used SAP but will give it a try. I've never had ETAB either. Seems like it is not as simple as I thought of. No wonder RISA can't solve the problem.
I am working on the load rating of a historic truss bridge. All the diagonals are steel rods which can't take any compression. I tried to use RISA but the program can't handle Tension Only (even you turn on the Euler Buckling option) and keep the truss stable at the same time. Even worse, the...
I wonder how AREMA specifies the rocking effect exactly. Chapter 15-1.3.5 says all the impact effects should be applied on top of each rail. But the rocking effect is actually calculated for individual girders. For example, if I have four girders spaced at 2.5ft, the gage is 5ft, then RE is 24%...
