AISC says that if there is a significant stress reversal, the connection should be designed as slip critical. This is clear for connections that have wind uplift reversing gravity loads; however, should this also include lateral force reversals such as for shear walls? I have my thoughts on...
Another wood structure collapse. This one has clean drop at joist buckets. Hmmmm.....fastening issue perhaps?
News story notes it as a "balcony collapse"; however, it is an elevated deck.

I'd be interested in your thoughts on the Daubert rule for expert testimony. (Google it...there's plenty of info on it) It has been required in Federal courts in the US for quite some time and is now being adopted by various states. In essence, it requires that expert testimony rely on...
I was recently involved with a case that was a personal injury (death) on a construction site. I don't usually get involved with personal injury cases but this was for an existing client and involved construction issues at the root of the death, so I was called.
A PEMB iron worker was setting...
Bear with me...this is a bit long: Litigation is over. Settlement received.
Contacted in 2007. Case settled in 2011. Remediation started in 2012.
Initial task was to evaluate potential water intrusion and deterioration of a 15-building, condominium facility in Northeast Florida, USA...
A bit harsh on the scientists in Italy, aren't they?!!
Penalty scale for geotechnical engineers in Italy....
1. Wrong soil classification.....10 years in jail
2. Incorrect prediction of long term settlement.......50 years at hard labor....the Pisa designers moved to France before being...
continued from an earthwork forum that I didn't want to completely hijack!
dgillette...can't do much in Polk County without it being related to the phosphate mines! I was in Orlando from '82 to '94, also with a company (Law Engineering) that is now part of AMEC (Law bought my company in '89)...
My practice is largely in construction/structural forensics. I have a need to show a "cause and effect" demonstration of improper installation of waterproofing on a wall assembly.
I've looked at several commercial packages for technical illustration, but would like some ideas on software that I...
Does anyone know of a source for older versions of the Metal Building Manufacturer's Association (MBMA) Manual? The 2006 version is readily available, but older versions seem to have disappeared. I checked with MBMA and they don't provide.
Specifically, I'm looking for translucent roof panel...
I am investigating an etching issue on some window glass in a building. I'm fairly sure that the etchant is hydrofluoric acid because of the rapid attack on the glass surface. Phosphoric acid would not have produced the same "signature" of damage and I don't know of any caustic material that...
Rather than hijack ControlNovice's thread on PE Reference, this is a different twist to similar issues...
I was recently asked to provide a reference for someone applying to take a certification exam for registration in a specialty consulting area (not required to be an engineer or architect)...
I am going through software reviews to decide on a new structural analysis package. I have now narrowed to RISA 3D, GT-STRUDL, and RAM-Advanse.
Your comments on any or all would be appreciated.
Thanks,
