Hello everyone, We currently have a problem with an access to a property which will require a ramp inside the property to compensate for the level difference. We are trying to design the ramp (in the property) such that a truck has no problems. At the beginning we thought a ramp with a 7.5%...

So Newman's book is not very clear about it (see attached). Isn't placing a secondary vapor barrier under the roof the typical detail for timber houses? In this case though, I don't have a plane substrate to support an underlayment so indeed It shouldn't go underneath. Metal sheet is an R panel...

Hello, There is a small fairly typical pre-engineered metal building which is going to be partly retrofitted for commercial use. The retrofit consists of placing a mezzanine inside of the building, and closing the envelope of this mezzanine laterally with insulated panels. The question comes...

Thanks everyone, Around here topsoil is not really valuable such that they come to get it. I lied, the owner does not clear all the soil, but removes only at the perimeter, for a firebreak indeed. Grass takes 1 year to grow back. I have come to the conclusion that the best is to keep doing...

This is a typical column for exterior cladding with a parapet wall, it makes a better constructive detail for collecting water and general detailing of the parapet. The roof should be placed at the discontinuity and so indeed it doesn't make sense to use it in the way you are showing. Maybe...

There is a 2 hectare piece of land which remains undeveloped but soon (between 3 and 6 years from now) the owner will start developing it (warehousing). This piece of land is essentially uneven dry grasslands, and each year the owner clears the organic topsoil as a fire management precaution...

Hello guys, thanks for the ideas. The metal sheets are corrugated, texture is galvanized (unpainted). Do you know if that's a good substrate for the liquid membrane? As I'm seeing on videos this is essentially a more elastic paint coating. Another option I'm considering is placing a new...

I have a small size metal building with a metal roof full of leaks. The roof is a 25yo metal roof with some air wind extractors here and there. The roof needs repair, but I wish it to be a cost effective and not so durable solution, as in 4-5 years the building may be demolished. What solutions...

Thanks everyone!

Can I achieve a slab on grade without control joints by placing sufficient steel mesh reinforcing? I know there are solutions with SFRC + mesh without control joints. I also know documents claiming 0.5% steel mesh works without control joints. Has anyone placed successfully concrete + steel...

anything?

Hello guys, A detailing question; What is your preferred way of detailing the eave (intersection of the cladding and the roof) in a regular metal building considering rainwater behaviour?. I attach some examples of what i'm talking about. I have seen many details and I haven't given it much...

Why not use continuity plates? thickness should be easy to dimension using tables (e.g., roark) with conservative assumptions

Hello everyone, All the cold storage building projects I have seen (-20°C) have either some sort of ventilated slab or some floor heating system to prevent frost heaving. This has been done this way for at least 20 years around here, in cold storage buildings. To me this seems as a very...

Hi everyone, What's your preferred way of sealing a concrete slab on grade subject to occasional oil spills (truck vendor)? Most of the time polished concrete + hardener works for me as it gives a smooth finish, but so far oils spills have not been a concern (they clean them with an oil stain...

Hello everybody, What's a good reference on cold storage/freezer buildings? Particularly regarding the detailing of thermal bridges and general technology available for energy efficiency. Kind regards.

Hello everyone, I typically design floor decks with studs in all beams and considering composite action for both the perpendicular and parallel to the deck beams, at least for the purpose of deflection checks. Nonetheless I have seen people who consider composite action only on the secondary...

Hello everyone, Is there any particular guidance documents, codes, or any writing, regarding the use of second hand steel members (beams, columns, purlins, etc.)? I'm referring to typical steel sheds or buildings that have been disassembled and now they need a new use. I would assume...

Sorry, attached you will find a picture of the situation. Interior pavements of the building is 6 inch concrete and exterior is asphalt. I finally ended up putting a small T steel shape in between. Its a detail I have seen (nor particularly elegant). Standard driveway curb is not very...
