Virginia has this section that gives the AHJ a lot of latitude in what they may request. ‘109.3 Engineering details When determined necessary by the building official, construction documents shall include adequate detail of the structural, mechanical, plumbing or electrical components...

RISA ... hands down ... No I am employee or I don’t get any kickback from them but they are a solid company and have tremendous customer service.

I think if you look close it's 300 ppl in an area ... not total occupancy of the building. Don't quote me on this but I think this was a difference in the IBC and ASCE-7

What is everyone using for seismic connection design? The new provions have an ASD section our people using this or using the ASD? Thanks.

Ok thanks, when I first read it I was thinking it meant that for a flexable moment connection that if the angle was attatched to the column with bolts that the angle must me attatched to the beam with SC bolts. So this really means that the bolts must be slip critical if the weld and the...

Can anyone tell me where to find an explaination of the types of lateral force resisting systems that are listed in IBC 2000 Table 1617.6.2. I'm really talking about what they mean by "detailed"," ordinary", "special" and "intermediate". Examples of what...

In the Schaum's Outline for Steel Design on page 163 in the connection chapter it says if a connection is to be made of both welds and bolts that the bolts must be slip critical? Where I can I find this in the AISC mannual or codes? Are these to be "SC" because of possible load...

Anyone have any good references for designing penetrations through concrete beams? Thanks.

What precaution and adjustments should be made during cold weather for the welding of shear studs onto a composite beam? Any good references or sources?? Thanks.

What are the primary differences in "Auger Cast Piles" and Cassions? Is there another name for an "Auger Cast Pile" Any good references for design? Thanks.

I am trying to reinforce an existing composite beam. The beam is a W12X14, 20' long, with a 5" concrete deck. There are 21 uniformly spaced shear studs across its length. Are their any references that cover something like this?

The reason I was asking this is in Das "Principles of Geotechnical Engineering" 3rd edition page 384 he talks about the how Jaky's equation under esimates the Ko if the back fill is dense sand. He reccomends using the folowing equation: Ko=(1-sin(phi))+(((dry unit weight/min. unit...

I'm trying estimate the min dry unit weight of a cohesionless backfill we will be using. I am in need of this value to estimate (Ko)for a wall with compacted backfill. I have: Max Dry Density D85 D30 Cu D60 D15 D10 Classification Any help would be appreciated. Thanks

What organization is the "Authority" in wood design and construction? What I mean by this is who is the equivalent in wood design and construction as AISC is to steel design and construction? Thanks

Anyone have any experience with using wood I-joists. I am considering using them and wood like some input from anyone that has spec'd them. I am looking at span of around 20-25' with 5/8" flooring above. Thanks.

Any input on top flange bracing of a W-shape steel beam with 5/8" flooring? I've read this is fine to do..Any comments or references on the subject would be appreciated. Intution tells me that the bracing strenth of the flooring is very minimal. Thanks.

Is there a standard for the minimum cover over a compsite beam stud? Any suggestions would be appreciated. Thanks.

Can someone give a me an explanation of the differences and when to use each of the two earth pressures. I've read allot about it it seems kinda vauge about when to use each. If you know of any good references that would be great also. Thanks.

Can anyone give me a good reference for the design of soilder pile walls? Thanks.
