Hey guys,
Thanks for your opinion on the subject. I've joined a picture of the glulam columns. You also can see the beam that support the hang the bridge crane on top of the column.
Yeah it is millimeter, pretty huge column indeed. They are holding a overhead bridge crane. I don't think it is delamination since the cracks aren't in straight line.
The cracks are principally between the lamina. But there is some important crack in the perpendicular direction of the lamina. The columns are ±300x600.
Hello everyone,
I recently did an inspection of a glued laminated wood structure which had a lot of cracking in the columns. The beams seemed to have little to no crack.
I think it's principally due to shrinkage of the wood, since I could unscrew bolt from the wood by hand. The problem is...
Any of you have a rule of thumb of about how long of shear wall you need in a building according to it's area/number of floors? I feel like I have a lot of shear walls, but the force is still huge...
I have a 1 1/2" slab on each floor. I used 20 psf for the roof and 50 psf for the floors.
The national building code won't allow me to use such smalls loads.
I also have to consider 25% of the snow load and 50% of the live load.
We also have the worst soil category for this, obviously...
I don't know yet, still trying to figure this out. I have shear wall of 30' long with uplift of 33.7kips and shear wall of 6' long with 45 kips.
Can you tell me if my seismic load is out of proportion? I got 461 kips for a 4 stories building of 12000 ft^2.
Thanks for the answer :)
Hello everyone,
One of my colleague is designing a 4 story wood building and having some trouble with the design of the hold down. The shear wall are parallel to the joist, so they don't support any dead load. The uplift at the base of the building for the smaller wall is 45000 lbs, we can't...
