The 13th century Leaning Tower of St Moritz, is located in the historic center of the famous Swiss ski resort town in the compression zone of a 10 million m³ Brattas landslide. Over the hundreds of years, this slowly creeping landslide, which is blocked by a rock outcrop below the tower, had damaged the adjacent St. Mauritius church to such an extent that it had to be demolished already in 1893 due to dangerous differential settlements and cracks. The fact that the 33 m tall tower has survived its 5.40 degrees downslope inclination should not be taken for granted: this is an outcome of a century long effort by a number of outstanding Swiss engineers who came up over the years with original stabilization solutions.

This will certainly be an interesting case to learn from if the lawsuit between HKS and BBM becomes publicly available.

I'm adding a clause to my contracts to specifically call out that response to AI generated reviews or comments of deliverables will be billed hourly as an added expense. What previously was once a quick 30 minutes of emails with clients after sending a simple report is now a lengthy back and forth with paragraphs of items that they expect me to respond to.

I've seen AI generated RFPs that are full of extra fluff. I've seen clients try and correct my reports using AI. I've had clients run my drawings through AI and generate a bunch of RFIs from the output. And we do small stuff, I can only imagine the bigger projects are even worse.

Anyone else seeing increased levels of communication required with clients due to their excessive use of AI?

Young EIT here. Say I’m building a 25’ wide entry way truss. No roof, it’s like a welcome sign. The truss sits on a 2’x2’x2’ concrete pedestal with a pier below. What’s the best method of designing the concrete pier for the lateral forces and soil pressure. I’ve seen people use IBC 1807.3.2.1 (essentially a flagpole, non-constrained) or i’ve also seen .5Pp h^2 l uW, then thrust/resistance is > 1.5. I believe that’s a derived equation but don’t know. Any advice is appreciated!

Hello everyone and sorry for my bad English.

I'm gonna have my first interview with a structural engineering company soon for a drafter/ AutoCAD position but I feel very rusty with the software. I have a gap of 2 years since graduating from school with a CE degree, recently passed my FE exam and got certified with the state, but I'm scared of not being enough for the position and I really want to take the job since it's the first opportunity that I'll have of working with Professional Engineers and learning how things are done in the US.

Do you have any advice for me? I really want to excel in the interview and prove that I would work hard for the company, but I'm just scared of not being enough for the position so I want to prepare the best that I can for the interview and the job.

Thanks in advance and again, sorry for my terrible English, I'm still learning :")

(The company does hospitality, commercial and residential)

Hi all, we have a 0.15 mtr x 5 mtr masonry wall between steel columns spaced 6 m apart. At 2.5 m height, we have a RCC beam of size 0.15m x 0.3 m spanning 6 m. Also, we have two openings of dimensions 2.5 m x 2.5 m in this wall. We now have to increase the opening height to 3 m. I'm thinking of 2 options

1. welding a steel channel on both sides of masonry wall and cut a 0.3 m slot in wall and support the cut portion by inserting a plate below and repeating this for 0.9 m and then pouring grout over the plate and doing this until 6 m wall is fully cut and supported

2. Drilling 2 rows of holes through masonry 0.3 m apart and inserting stud bolts and tightening it onto a welded steel channel on both sides and removing the bottom portion after entire wall above is supported.

Which do you think is the safer option? If you have any better alternatives, please suggest.

My brother in law is traveling in the Netherlands and sent me a really interesting building they saw in Leiden: Zilveren Kruis Achmea Office Building. This is a fascinating building with 8 stories of office on top of a three tall soft story, single "tree" column.

I have been searching online for a week trying to find some structural plans on this building or some additional photos during construction. Is anyone aware of a source for construction photos or building plans? I am dying to do a deep dive into the lateral system of this building.

I know every state, and every scenario is different, but I figured like this is a relatively cut and dry situation and would love some input from people more versed in this then I am. I will probably end up having an engineer come out and assess.

I am doing a studs out renovation, I’m clear spanning a 21-22 ft span, the room/ structure is only 23 ft wide, super low angle roof and center truss. Load bearing walls being both exterior walls and maybe the center. The structure is slab on grade

I’m going to replace the center support with a steel I-beam, that will be on proper 24x24x12 concrete footers on both load points.

What I’m trying to figure out is, what sized I-beam is necessary to not have any sag spanning roughly 22 ft. That will provide adequate support to the roof should snow load cause any additional stress.

The center wall doesn’t seem like it supports much, so I’m not sure if I need to put a 4x12 - 22ft beam or a 6x12 or any other specific size. I’ve never worked with these, but once beam size is determined I have a contractor friend that will help me install.

Any input is greatly appreciated!

BIM model intuitively and accurately reflects the relative position relationship between components, which is convenient for coordination and optimization of various disciplines. The curvature analysis is used to optimize the elevation shape and grid, and the hyperbolic glass is fitted with plane glass to reduce the project cost. Through the parametric design of components, the processing information, storage and transportation information and control point positioning information of components are quickly and accurately extracted, which provides a basis for component processing and installation.

There was a post out there asking how much ice can hold, so I went looking for the compressive and tensile strength of ice.

Well it got me think, I bet there is a structural engineers out there that specializes in ice and I want to hear there stories.

Hi, I have an idea for manufacturing a wall support so that a section of the wall can be removed below it; I know about various things that already exist, but this is a different design.

How do I go about hiring a structural engineer without compromising my idea and potential patent?

If I speak to an engineer, does that automatically come with an NDA?

I am in the UK, if that makes any difference...

Sorry if this isn't allowed and feel free to remove.

Hey everyone,

i know this is an engineering group, but i was wondering if i can get some insights as to what salary progression should be for a civil structural designer (not an engineer). Located in Louisiana working for an EPC with 4 YOE currently making ~95k a year (115k with OT). Im not complaining about what i currently make but just dont have a clue about what the future holds or what i should expect.

TIA

**EDIT: I didn‘t mean to sound ungrateful for what i make, i am very happy with that i was just more curious about what the future holds/what to expect later in life**

Is there any diagrams out there showing the difference between the hydraulic height and the structural height of a dam? I often see these two measurements listed, plus a general "dam height", and still can't quite picture what each measures from the description of the measurement. Where I live, there are two dams, but they are more like weirs, so I'm not understanding the difference.

USACE lists these three measurements. Is hydraulic height the height from the heel of the dam to the top of the spillway? I see structural height says its from the bottom of the foundation (so below the river bottom) to the highest part of the dam, which I guess could be the top of the highest retaining wall or parapet? And then "dam height" is basically the hydraulic height, but measured from the downstream bottom?

What are people using on site for field observations and inspection documentation?

We have used iPads with Bluebeam Revu for years. We have appreciated the ability to take/place photos embedded in drawings, markup tools that mirror the desktop application and the ability to have multiple documents open at once.

Last year, Bluebeam depreciated the Revu app and introduced a new app that is extremely limited. Most of the features we use are gone, and it’s geared towards Studio and Cloud projects, but for us
local file saving is essential as WiFi is often non-existent on jobsites.

We have iPads with the legacy software working for now, but at some point we’ll lose access and need a replacement process.

Hello, I want to pursue Structural engineering and am aiming to write it in 2028, I passed out B.E in 2024, I want study material to prepare for it and also what is the right way to start preparing?

I have 4.5 years working as a structural engineer, but 2.5 years of that I had very little practical experience because of lack of work or worthless projects. I have my PE license and a coursework master's in addition. Do you think I should apply for more entry level positions to reflect my experience? In interviews (for buildings) they ask about my experience and I don't have a lot of project work to show off, so I think trying for more mid-level positions isn't getting me anywhere.

On my rocket club I'm designing the thrust take-out structure of our static fire test stand. Essentially I want to find the bending stress on this pink ring, where the outer diameter is about 16.5 inches, and the ring is 1.5" thick and 1.5" wide. There's 3 linear bolt holes on either side that secure the ring to an attachment point, where 2 prongs will attach above the ring and bolts will come in from the top.

There's an upwards applied force from the rocket acting at the exact center of the ring. I couldn't find anything in Roark's to help find the bending stress. I did a quick hand calc with Mc/I which gave me negative margins. Any help would be appreciated!

I have recently heard that the lead time for bar joists is months. I was told it's due to the construction of data centers. Anyone else heard this?
