Seasons Greetings - In my new volunteer "job" as in-house engineer for our homeowner's association, we have two (2) pedestrian bridges that need replacement ASAP. My general arrangement sketches of the existing six (6) feet wide wood bridges are shown below:
In both cases replacement...
Engineering-Tips member PEinc is one of the top contributors in Geotechnical and other forums. It's easy to see why after reading the linked article that is published in the current issue of PileDriver Magazine. He founded this business about 30 years ago and has a portfolio of impressive...
The U.S. National Academies of Sciences, Engineering, and Medicine makes available informative books on various subjects. Most, if not all, are available as free .pdf downloads. Here is one that I saw listed and briefly looked at today:

Sinking Cities Preview (1.5 Minutes)
"As the earth warms, sea levels rise and super-storms become more frequent and intense, many of the world’s major coastal cities may soon be under water. This series explores how four global cities are coming to grips with the real-time effects of rising seas...
Whether global warming is "true", "false", "caused by human activities", or "natural" has been talked about frequently in other forums. Sea level change is often linked to global warming. Unlike global warming, sea level change has been documented by comprehensive real-time data collection. On...
Last weekend my wife's daughter and her family visited the area for several days. Had a chance to spend time with my 13 year old technically inclined (step) grandson. Introduced him to the fundamental use of a Slide Rule - he was not only interested but wanted more problems to work.

One of my younger cousins is planning on getting married in the spring. Over the weekend she asked if I would perform the ceremony - I am quite honored... and surprised. It will be a modest size wedding at our late grandmother's home. Of course I told her "yes". Now, am in the process of...
My uncle (a structural engineer) sent the newspaper article attached below in 1988. Neither he nor I had heard of fragipans. Since then, have not seen any more about them. Found some basic info on the internet included this map. Anyone had experiences with fragipans?

For Engineers working on historic project restoration / conversion, I've put together a page on my website with links to a wide assortment of historical building code info:
Assorted Historical USA Building Codes: 19th & 20th Century
If you need just a general idea of early 20th century...
The current issue (August 2015) of "Civil + Structural Engineer" magazine has a number of links to various universities that have online Civil / Structural masters programs. Here is the article:

AISC Design Guide 15 is a recognized source of accurate information concerning the historical use of structural steel in the USA. In general, it provides information on various structural shapes and design criteria since 1873.
Some time ago I realized that Design Guide 15 does not correctly...
The latest scanning project is now complete, and I've uploaded this US Steel catalog to my website. It has not only the usual wide flange, channels, angles, etc., but also crane rails, corrugated sheets, sheet piling, floor plates, and "Wide Flange CBP Sections". The latter are H-piles...
BigH, thanks so much for your recent post card. We were delighted to hear from you. In fact, my wife's grandson has a small stamp collection. He will be delighted to get a stamp from Thailand!

Questions come up on Engineering Tips about relevant design guidelines for out-of-the-ordinary steel structures. The AISC Specification does not appear to cover these situations. The "Steel Interchange" section of AISC's November 2014, issue of "Modern Steel Construction" magazine addresses...

I've scoped out the internet for as many of the classic proprietary steel handbooks, like the "Carnegie Pocket Companion" as I could find. Turns out to be more than expected... 41 so far. They cover wrought iron and structural steel members from the late 19th century well into the 20th century...
Now that your first year teaching at the Gonzaga University is complete, please give us an update on how it went?

I'm advising a local private community's management on a proposed project to seal coat not only the two small asphalt paved parking lots, but also the approximately 2 miles of paved asphalt streets. I used seal coat on a parking lot project many years ago and have a low opinion of its benefits...
I've finished scanning the 1934 Carnegie Pocket Companion and have posted it on my website. It has the usual structural steel products manufactured by Carnegie, but also other information that may be useful to engineers working on older structures. Here are some examples:
