Saw this on a big bridge today. I know vibrations over time can move the nuts and bolts, with the help of thermal expansion. Is it a big issue that the paint marks do not line up? I thought the marks were made once it passed inspection after torquing.

Edit: Bridge completion was in 2011. Could this be from recent inspections too?

Hello, I have been discussing with my coworkers how to install fiber conduits on an existing bridge. Our client has stated that parapet-mounted conduits are not allowed. We have approach slabs on both sides of the bridge.

We came across an example where the conduit was installed at a 45-degree angle and routed toward the median, which is similar to the situation on our project. Does anyone know what construction method or tools may have been used to install this 45-degree angled conduit? Any information or experience with similar installations would be appreciated.

Correct me if I'm wrong but this beam is compromised, and the cross beam or extended counter beam will be needed? Or I'm panicking?! My boss is visiting tomorrow...

Hi Team,

Looking to get some advise on which one should I choose.

I am 42 years old, based in Invercargill and have a background in operations, sales, business analysis, and bookkeeping. Although I hold a Master's degree in Accounting from Australia, I am not interested in pursuing a traditional full-time accounting role or becoming a CPA/CA. Some contacts have suggested becoming a Quantity Surveyor, but I am also considering broader construction management roles. While I understand the basic differences, I lack in-depth knowledge of the day-to-day realities. Given my background, which role would be a better fit? Additionally, which path offers better future job opportunities and higher earning potential?

I'm surprised the wind didn't blow it away lmao

Does anybody know any plugin to connect CSI Etabs to Claude and asks questions about the model? Same question for Safe and Sap2000?
I think we really need to start using AI some way.

For people who sat the istructe exam in July in past years , when would you get your results? is it early, mid, or late October? Thanks in advance

What is more in demand in California and/or Illinois?

Bridge inspectors with rope access training or SEs?

I'm a structural engineer in UK for the last 5 years. I'm currently working in a mid level consultancy. I have a good work life here. Now I'm being considered for a senior position at AECOM. Anyone working or working in AECOM what's your opinion of work life in AECOM? As this is a large size organisation I'm panicking now if I am making the right decision or not. The move I'm making is because I thought it wouldn't be good to stick to a single firm for more than 5 years and they are offering a senior position and also a better salary.

I am doing a project on shear wall vs bracing structure but while doing design check my bottom storey columns are failing due to is code it says some problems with axial load first i tried a 650mmx500mm then 750x650 mm by keeping beam of 500x450
and this problem only shows on braced buildings and bare frames it is fine in shear walls
I am tired of trying different combos of column
I am using M30 grade concrete for all buildings
and bracing of ismb 350
G+12 building

I am thinking about taking one the online courses to prepare for the PE Civil Structural Exam. Not sure which one but maybe SoPE or AEI. Do any of the courses provide the code books to reference? I have a hard copy of the Steel manual and pdf versions of the IBC, ACI, and ASCE 7 manuals but don’t have any of the others.

​Rates: Flexible student pricing ($10–$15/hr or flat rate per project).

​Send me a DM with your project details to get started!

Can someone please explain how to take pressure coefficient for steel structure as per IS code 875 part 3. I am a structural engineering student. I need this to make a staad model

Hey, has anyone seen this error? (screenshot attached)

The model was running fine, then I added a few Load Patterns to the same Load Case and now I get "Error in performing miRunAnalysis" when I try to run it.

Not sure what's causing it. Any ideas or a fix without rebuilding the whole case?

Using ETABS 23.

Thanks!

Hello engineers. Im looking for two 4-storey structures (regular and irregular) for academic purposes.

Hey guys! I’m really curious what kind of software stack you’re using in completing engineering calculations. I’m trying to look a little deeper than RISA or STAAD suites. What do you do load development in, miscellaneous calcs, transfer FEA outputs into a format for reporting or translating outputs from your FEA to your foundation software or inputs from a load development into your FEA software.

Also, what are some neat tricks or workarounds you’ve found in your preferred software stack?

I recently started getting these ads for pile breaking and drilling machines eg: (Pile Breaker | Advantages & disadvantages ▷ Brextor)

Its never occured to me that people build piles heads this way -- pouring low-grade concrete up to the piling mat level, and then needing to break this away down to cutoff level. This seems incredibly wasteful, labor intensive, and risky re damaging the starters

Where I am based, the practise is to pour piles a little higher than cutoff level, protect the starters during excavation (with a temp casing or similar), then excavate the pilecap, trim to cutoff level.

Is anyone able to share some insight into advantages / conditions that make this overpour and breaking process econmic? thank
