Thanks guys, when comparing to lightweight topping in light frame construction, my main concern is the heavy traffic in a high school (I would not be certain with the lightweight gypsum topping...)

Hello all, We are working on the design of a new high school and the client's intent is to go with CLT floor panels covered by a non structural concrete topping. They want the topping to be maximum 2 inches thick. I found papers and case studies where they had 2 in toppings, but my concern is...

Hello all, anyone know of a smart way to reinforce Floretyle concrete system? The architect wants to add weight... Thanks!

Thank you all, have a great week-end!

If so, is there any documentation on this?

Hello all, I have a case where the formwork system has tie rods that are removed with the formwork (see image). Cones at both ends of the tie rod are filled with mortar, but it leaves a cylindrical void inside the wall. Does that affect the fire rating of the wall?

Awesome, thanks a lot!

Hello all, Does anyone know good technical references for building relocation? We have a project where we need to move an historic (wood structure)building and I don’t want to miss something. Thanks!

Interesting article Enable! In my project, which is also in the great white north, wet curing is done with Ultracure blankets that are wetted once before applying thermal blankets (no continuous water flow). As for the hydration, the way I see it, if there is a problem with the heat in the first...

Hello all, A contractor on a pretty large project is arguing that we should not apply wet curing for suspended slabs during the winter (cold weather, below freezing point). I don’t agree with them, slabs are heated from underneath and insulating blankets cover the slab... do you have any...

In my area wet curing is mandatory for slabs. Curing compounds will never be equivalent in terms of shrinkage control(in addition to the flooring issue)

Thanks a lot Mr Kootk, much appreciated!

Hello all, I have to design a RC corbel that is anchored on the side of a RC shear wall (parallel to the shear wall, see below). This design is quite simple for a RC column, where the truss analogy is well defined. In my case, since the wall in long, I have a hard time figuring out how to define...

In theory, I would say the answer is yes. The flexure/shear component of the stiffness changes with the slenderness of the frames. However, if the building is very simple and regular, it is safe to assume that the relative stiffnesses is constant for every floor.

It wouldn't make sense if it was the area of the zone. The way I see it, gust speed can be higher for a small area, thus a higher CpCg

Hi, I attended a seminar in Quebec City on 5-6 story lightweight wood structures. I recall 3 major challenges specific to these structures: 1. Fire safety requirements (non combustible cladding, fire separations everywhere, etc); 2. Vertical deformations from shrinkage and creep in sill plates...
