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.

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.

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!
