Very active Connecticut town Amtrak bridge over ocean inlet built in 1905. Various ‘repairs’ but horrendous overall condition. Amtrak has told us they know what they’re doing.
So I'm doing my dissertation on bridges and I thought it would be a good idea to use FEA so I could learn how to use it before I get into a job but I decided to learn how to use SAP2000. I've got my grasp on the basics of it and followed a bunch of tutorials on how to use and I can confidently model simple buildings. Since I could make simple structures I decided to finally start on modelling bridges the bridge decks I needed for my dissertation but for some reason I just can't mesh my steel beams to the deck and whenever I run the model it looks like the pic I have on this post. There was another attempt I have done however it looks wrong to me since the deck isn't actually on top of the beams when I extrude the objects but idk if that's just how it's supposed to look. If anyone could please let me know how to resolve this please let me know. PS Ik I could be using CSI bridge but I don't have access to it
To me this section looks intended for in-plane rather than out of plane. For a wall that is only taking out of plane wind (not part of the MWFRS) the max moment would be at a zero shear location, so their equation would be divided by zero? Thoughts?
materials: wooden sticks and hot glue.
these materials are obviously limited but how do i know which bridge structure is optimal?
I'm a grad student taking the structural PE in about a month and need study resources! I dont have a company to ask for resources or comp expensive study material/courses so if anyone has any practice problem pdf's or any study material they could please send me, I would be so grateful🙏🙏🙏. Thank you!!!
Hi
I was trying to work out overturning stability of masonry wall for small sections against the Wind speed.
I have seen code but not able to exactly understand what code needs to use for that.
I have a wind speed, dimensions of wall, locality details.
For context it’s Australia standard to be used.
Regards
