Rules

I am searching for a good manual or guidance with worked examples if there is any. The software itself seems to be outdated a bit but very useful.

I'm a preschool teacher and the kids are currently fascinated with bridges, thei designs, the stories, and the beauty. I am pretty unequipped with my knowledge of bridges and was wondering if any of you bridge experts had any book recommendations for myself as well as for the children.

Thanks! Go bridges!

Thinking about visiting Guizhou province, China since there are obviously quite a few impressive bridges there. Would love to see them in person. Anyone has done just that?

Would be great if I can see 3d models or construction plans of some of them beforehand but they are obviously nowhere to be found...

This is a question for my bridge engineers of reddit. How do you put Bridges an alligator infested waters? Lakes, rivers, etc? I haven’t found this anywhere on the Internet or even reddit, so I guess I’m the only one who’s wondering. The thought process that started this whole scavenger hunt was the fact that I went somewhere that has a little bridge and you could walk out onto the water and look at the turtles and such but there was a whole fkn alligator in there; So naturally this made me wonder, HOW THE HELL is this process done with dangerous animals around???? please lmk or share your experiences.

Hi there,

Came across this subreddit recently, would be great to bounce ideas off one another when working projects. I live in the UK so use a mixture of the DMRB and Eurocodes for design.

Where are you working? :)

Hey everyone, I tried searching but didn't find anything that helped. I'm building a wooden hiking trail bridge that requires 24 foot stringers. I'm making 3 laminated stringers using 2x10 treated lumber. The problem is the longest dimensional lumber I can get is 20 feet, so I'll need to splice them together, and I know that the splicing will weekend the beam.

So, my question is, is it better to space the splices out over the length of the beam, or better to have as much intact wood towards the center of the beam and have the splices closer together but towards the outer portion closer to the banks. I know the compression and tension forces will be highest in the middle, so my gut says to move the splices to the outer portion.

Any thoughts would be much appreciated, and thanks in advance!

Hello,

Can you please share any resources to prepare for the IStructE CM exam, especially for the bridge question?

For those of you not familiar with the exam, the bridge question requires one to propose two different concept designs for a given situation. These are almost always unique design situations including several site constraints. The biggest challenge (particularly for me) is to be able to come to the best solution in terms of form selection.

Amsterdam’s robot printed footbridge welds steelwork with state-of-the-art technology

The award-winning design, developed by Dutch technology start-up MX3D together with designers Joris Laarman Lab and a host of collaborators, offers a glimpse into how computational design together with state-of-the-art robotic welding technology could shape our cities in the future.

Hi all, I am a bridge engineer with about 12 years of technical design experience at the moment, and I am interested in understanding how you have picked up the specialist skills that our discipline requires?

Particularly in closing the gap (bridging you might say...) between university degrees, and construction ready bridge design, detailing and drafting. To develop high quality, robust but non-conservative designs there really is a steep learning curve to be navigated.

Did you get to spend time on site see bridges get built? Did you have the benefit of joining a team of grey hairs who were willing to share their knowledge? Or are you self-taught?

I myself joined a really small bridge team in an office of a multinational (Arup) and was lucky enough to have to do all of my own design, detailing, drafting and construction supervision for the first 4 years of my career. My direct boss was also a good bridge engineer, although not an absolute expert, so i needed to self teach a lot of the more complex aspects. I had access to an internal network of others, however they were often more keen to ask more questions than actually provide any meaningful answers, and the rest is history. I have designed about 70 bridge structures ranging from 6m span culverts right up to 2.5km long road viaduct type structures, and plenty of road signs, fences, retaining walls and pits along the way.

Keen to hear some of the collective views on the way you got to where you are and how you picked up some of the more complex skills like, secondary effects in prestressing, construction stage analysis, non-linear analysis etc. etc.

I am currently working on an integral pier bridge. My solid section super tee is not working since area where i can put reinforcement is very limited.

Does anybody has related experience regarding this?
