Can you use plates and glulam rivets?

The subbase is part of the asphalt pavement system and contributes to the strength. Without it (I'm not sure you can) you would require...

When I first started engineering, there were a couple of Chinese engineers that actually used them... like a sliderule, but very...

Steel may be less expensive than the conc fill and the effect of the concrete fill may be lacking.

Can you increase the column size rather than go for a composite section? It's generally more cost effective. I occasionally use...

I'll be 76+2 in a couple of months... and still playing engineer.

OK... I'll check to see if there's an equivalent to the formula... I just added it as another check to my SMath program. Thanks...

Recoded it decades back to eliminate disk swapping. Current rig has 64G RAM... a real change.

It's the same as the Eq. 9-30 that I added. I checked it for both U values (compression and tension and used Fc to include axial load)...

Thanks... it's 9-30, I've already included it. I'm not so sure... my first 2-D frame program was written so it could run in 64K RAM by...

Does RISA list the formula used that gives the low value? I'd be curious to see what it is.

My 3D FEM program, written in Fortran 50 years ago has seen some marvellous projects. I've used it for tip potentials for...

The capacity based on 9.30 is OK... I have built in more than 25% for my own comfort. "Are you just checking the tube wall itself or...

I've got to send it out to Brian... my 3D FEM program 'broke' when I switched from Win 7.
