You'll want to remember that building footing frost depths are not only based on how far down the frost goes. Frost heave on structures has a great deal to do with how the soil freezes to the exterior foundation wall and lifts up the building from the side. While frost depths vary...

I have run into this problem on almost every multistory stick framed building I've done since the IBC came around. My company has come to the conclusion that if you have joists framing into a fire wall - using a double wall or adding a post and beam line at each side of the fire wall locations...

In my opinion it would be tricky to share the design of a PT parking ramp with the supplier. It could work, but you would have to set up good channels with the supplier's PT engineer and preferably have them on staff prior to bidding the documents. The main issue that I see you having are with...

You can surely use bolts to attach to the column and a weld to the beam without the bolts being slip critical. You need to consider the force level of your free body diagram and not so much the member level. For example, on a moment connection from a beam to a column you could weld the shear...

I've been involved with light gage for awhile and I've never seen anyone camber floor or roof joists for the serviceability benefit. Not that it wouldn't help, but I don't think it would be economical and (nothing against drywallers) they may not be installed properly.

Some further gossip on the matter: I have heard the Masonry Society has stated the requirement in the ACI (short lap lengths) is staying the way it was written and the IBC (long lap lengths) are changing to match. This source said that the IBC lap lengths came from ultimate design and was just...

Thanks for the input so far. Prior to posting, I did read thru a couple of previous threads, including rrmiv's prior thread. They had some very interesting information in them, alas my extensive thirst for knowledge has not been quenched yet. I'm not sure that just "ignoring" the...

As I'm sure most of you masonry rebar lappers know, the IBC has some hip, neat and groovy provisions for the development lengths of rebar in comparison to our old, able-bodied friend, ACI. Being a good, conservative engineer, I've limited my masonry wall reinforcing to #5's. This is mainly...

I have a 1960 doxplank manual which includes original spec and allowable loading info. Let me know if you want something: agrant@bkbm.com.

I have had good luck with helical (screw) piles in vibration sensitive situations. For examples look at: http://www.atlassys.com/
