A little more information.. (I read a few other related posts on here, so I thought I should clarify) I'd like to know if there is a standard for frequency and procedure for inspecting anchorage points - not how to design them, although I may need to do this eventually to evaluate what's there...

Does anyone have experience re-certifying/inspecting the suitability of anchorage points on a roof for attachment of a personal fall arrest system. I've searched the OSHA website with little luck. Although they give some general testing guidance in 1910.66 & 1915, they go on to state the...

yachtdr, Thanks for replying, I'm surprised no one else is in our boat. I checked out NU's website, it was actually the first private college to offer an engineering degree in the country, 185 years ago. The program requires a 1 week residency at the university upon completion of all...

I am considering a Masters of Engineering through an online program offered by Norwich University. Norwich is a 'real' university in Vermont (i.e. not a Phoenix type) with an ABET accreditation. The program is composed of 1/2 engineering coursework (structural) and 1/2 program management. It is...

I've enjoyed this chain and thought I'd chime in. I've worked at three different companies over the past 5 years in senior engineering/project management positions, all with different types of managers and have left each time by my own decision. I now have a low stress job with decent pay in a...

For what it's worth, I've read that a minimum you should look for is the NYSHD Certificate # on the bottle's label. Not sure what the qualifications are, but at least it's been through standardized testing. As a side note. I just ordered a water filtration system for my home. Our drinking water...

Okay, need help with this one... I'm a structural engineer and I've been asked by a customer what type of sand should be used for a drying bed; Lindeburg provides not guidance and that's as deep as my WWT knowledge goes. Can anyone help with a typical spec for drying bed sand? (My guess is...

Thanks again BigH.

BigH Thanks for the info. Can you please check your links, the first one sends me to EBay and the second to Quest. The timber piles are currently in use and supporting a concrete beam that a travel lift moves on. The owner wants to upgrade the travel lift. I have been asked to determine the...

Clarification, the timber capacity is for 40' x 14" o.d piles, about 20 years old in brackish water. Thanks.

Does anyone know if there is a simple method to go from SPT data to existing timber capacity? Is the ENR method acceptable if the area of the SPT is scaled to the pile's area? Thanks

Thanks for the input. Yes the pistons are stainless but they have seen quite a bit of salt spray. I haven't researched the type of stainless so I can't comment on their resistance to corrosion; I doubt it's an exoctic type (i.e. duplex stainless). The bottom line is it's that the client has...

I am designing a system that utilizes two large dual-ram hydraulic units for deployment of a satellite antenna. Our customer is concerned about pitting of the stainless steel and sand/grit sticking to the surface; ultimately the concern is that both conditions could lead to possible leakage at...

Okay, so it's a new year and no luck finding this book. Suggestions are still being accepted. Thanks to everyone who has taken the time to reply.

Sorry to hear about his death, I found an online resume (apparently rather out of date)indicating he worked at JPL. I haven't seen any other books available that deal specifically with this subject. I called Reiters about 3 days ago and the employee said that they had just sold their last copy...

IEEE needs to update their website, it's no longer in print or available there. I think they have may turned over their printing to Wiley. I've also emailed the author (Roy Levy) at JPL but haven't heard from him. Thanks anyway.

I am looking for a copy of "Structural Engineering of Microwave Antennas", published 1996, author Roy Levy. I have checked with no luck, every possible place I can find on the internet (new and used). I'm more than willing to settle for a used copy. Suggestions are welcomed.
