HI everyone, We are constructing a number of silos in high heat conditions ( approx. 50 degrees Celsius). We are worried that the cement hydration temperature will exceed 75 degrees Celsius( as it happened with other silos). The method of construction is slip forming. Does anyone know any...

Hi Everone. I have a general question regarding a career change. I have 8 years of experience in the design of buildings (steel, concrete, etc.) and thinking about switching to marine (offshore) structural engineering. My job isn't as well paid as I wish, there are crazy deadlines, and I can't...

Hi everyone, I am not used to Eurocode as I design mostly in BS. However, I wonder what Eurocode SLS combination with wind do you guys use to check lateral deflection of a portal frame at eaves( due to wind). In BS I always do 1.5 wind + 1.0 Dead..what about in Eurocode? Many thanks!!

Hi everyone, I am designing a pitched portal frame elastically and need to check the stability of the haunched section of a rafter. As I don't have an option to use software , I have to do it by hand. I know how to conduct checks (lateral torsional buckling,combined lateral and axial,bending...

Hi everyone I have been tasked to provide the value of a line load under a timber wall subjected to wind load. The wall will sit on a beam. I know how to calculate pressure under shear wall/retaining wall, but I have no clue how to approach the problem. All they need is the line load from...

Hi everyone I am really stuck with the design of a 350 mm thick flat slab (no column drops). The structure is a podium supporting five floors above. As the structure has an irregular column layout, line loads and point loads located in random areas I intend to design it with FEM. I previously...

Hi everyone, I have an I beam in torsion due to supporting a section of a masonry cladding. What limit of rotational deflection ( in degrees) do you use? I read that it is 2 degrees, well in the UK at least. Would you share your thoughts on this? Thanks

Hi everyone I am starting a job in structural engineering and something is really nagging at me. The question is probably stupid but..well there it is. In a Multi-storey steel braced building a column splices are located every third floor (as I read that sometimes it might be the case) just...

Hello everyone we have a concrete cement silo structure and contractor is to watertight the roof. The roof is steel deck concrete deck sitting on steel beams. The design of water proofing calls for the use of foam concrete (1% slope) then bitumen layer and screed on top. The contractor wants...

Hi everyone I have a question regarding water resistant mortar. . We have a concrete water tank for cement plant and the drawing specifies that the concrete wall on the inside is to be coated with 20mm water resistant mortar. What would be the proportions of cement\lime and sand for such...

Hi everyone, In the base of a column of a lift shaft there is a requirement to install M20 8.8 Hilti chemical anchor, however the contractor for unknown reasons installed expansion M20 anchors of similar properties. The base of a column is in the proximity of a lift pit ( the closest bolt is...

Hi everyone Quick question.. we have a rigid pavement construction with subgrade ,subsbase ( engineered soil) ,base course (gravel) and finally concrete slab. The contractor compacts subgrade and subbase course with a roller, but I wonder if base course (gravel) also need to be compacted?

HI everyone. Would anybody know the specifications (length of weld, spacing between welds, etc.) of intermittent welding of diamond 4.5 thick hot-rolled steel plates to steel structure, as means of fixation. I have been looking everywhere and I just cannot find anything on the subject. Thank you

Hi there First of all, I have zero experience with drainage…. I am more from the structural side, but I am required to deliver so… The contractor was excavating an area for a drainage channel and encountered a conduit with fibre optical cable in it. The position of the conduit would be almost...

Hi there everyone. First of all, I have zero experience with drainage…. I am more from the structural side, but I am required to deliver so… The contractor was excavating an area for a drainage channel and encountered a conduit with fibre optical cable in it (rerouting of the cable not an...

Hi everyone I have a concrete structure with steel beams and column that support side rails for cladding. The columns and beams are in the concrete frame openings and are connected to the concrete frame with bolted and welded connections as per design. Please see attached drawing for...

Hi everyone I am tasked to deal with sealing openings in metal roof of one of the cement plant structures( belt conveyor). There is a bunch of loose sizable cables running in a cable tray and through single skin corrugated metal roof sheet ( no insulation just the metal sheet). How will I seal...

Hi everyone. There are to be four water pipes running on the roof of a concrete structure building. The roof is already constructed (please see diagram provide depicting all the layers). The pipes will be rest on some kind of supports (it has not been established yet), however I wonder what...

Hi Everyone I was just curious, in the equation for permitted deviation of steel structures ( to Eurocode), what does the small letter 'n' stand for?? I Can't find an explanation anywhere.

Hi everyone During my visit to a site I have noticed steel connections I am not familiar with ( it is a heavy industry Cement Plant and I have zero experience with this).Would anybody know what type of connection is on the picture? I originally thought it was an end-plate pinned connection but...
