Haunched girder with floor beam deck system. I will use Midas Civil to run the analysis, extract all the load demands of consequence and use spreadsheets to run the capacity check and subsequent load rating factor calculation.

I do this a lot for bridges that are not appropriate for modeling in Brass Girder. Otherwise, you will need to establish your own set of excel spreadsheets (or similar) that can perform the capacity checks based on your analysis from the model. They can analyze beams based on stiffness as well, so your haunched beam problem can be correctly analyzed for live load demand and capacity in these programs. These programs are not hifalutin but they are excellent number crunchers per AASHTO code. I don't like them and I find other options to be quicker and more transparent.ДЇor your particular problem, unless this bridge is curved or highly skewed, I would use Brass Girder/BrM (as MIKE 311 mentioned). So, with this being said, I have used the Load Rating features of Midas Civil in the past but I don't anymore. Member check for a large steel truss with lots of members (think overhead sign bridge) 2. What I don't use it for is design, and by that I mean to calculate capacities of an element. I use Midas Civil a ton for analysis, and what I mean by that is that I use it solely to extract force demands from the structure under a particular loading combination. Once you have gotten good with Midas, you can model even a complex bridge in a matter of a few hours.Analysis and Interpretation not included. What I like is that it can still be used as a general FEA program that gives the user lots of freedom to create custom models but is tailored toward bridge design.

Maybe not as powerful as Lusas but still really good and a lot cheaper. I find it to be a really powerful program.

I guess, technically I am signed up as one of their 'Experts' but don't really do anything with that title. I use Midas Civil exclusively as a FEA tool in my office.
