A wood panel diaphragms in a single family homes or duplexes are permitted to be idealized as a flexible diaphragm without justification per ASCE 7-05, 12.3.1.1.
Wood diaphragms in larger buildings such as multi story apartment buildings, warehouses/supermarkets, etc shall be explicitly...
I do share the same frustration in the amount of error in the AISC manuals as it is similar with other manuals/codes we use in the practice of structural engineering.
The number of errors in future editions will not decrease if they continue their attempts to make an exact science out of what...
Same as Mike here. Foundation plan shows structure above, all other levels show structure below.
I like reverse-polish too but does that mean most non-engineers prefer the polish logic?
I agree with JStephen. Review of anything, ideally, should be done by someone of equal or better caliber. Of course, it is very subjective. As a minimum, PE's work should be reviewed by a PE and SE's work should be reviewed by an SE, which isn't the case in many jurisdictions.

An engineering package shall be self-contained and in itself, fully describe the engineer's design. It is not acceptable if a "competent" reviewer has to physically communicate with the engineer to understand what he is doing. At the same time, it is not the rold of an engineer to "train" the...
While using a hatchet where you need a scalpel is inappropriate, the reverse is also not appropriate. When producing calculations, include sufficient units, equations, references such that when you see it five years from now, you can still follow. Expect the same from the submitters.
For top of slab, I use T.O.C. for Top of Concrete (not to be confused with Table of Contents). T.O.C. is used whether it is on slab-on-grade or top of concrete filled deck.
Provided that SOG is defined in the list of abbreviations and no other disciplines defines SOG as something else on their...
I find doing it by hand by far the quickest way to distribute a single level horizontal distribution to LFRS below. This gets you a "rough" idea how the story shear will distribute. Understanding of direct shear and torsional shear is essential.
Creating a computer model may get you more...
- Before performing ANY task for anyone, get the job number to charge to.
- Don't be too far ahead of schedule. Stuff will change.
- Get used to the QA/QC process.
- As many already mentioned... think twice, speak once.
Older codes simply required 100% of the story shear taken by the concrete walls and 25% of that into the moment frames. Newer codes require the story shear be distributed to the shear walls and moment frames in proportion to their relative rigidities, but still moment frames shall be designed...
Purchase a copy of the 2005 Edition ASD/LRFD Manual for Engineered Wood Construction published by AWC AF&PA for general information on engineered wood products.
For specific manufacturers, like others indicate, iLevel is the site to visit. I had no idea Weyerhaeuser introduced this new "brand"...
Mistakes in the "content" of the drawings fall under "unforgivable" and the guilty shall be punished. The degree of punishment depends on the amount of money it costs the company to fix the mistake. For the most part, mistakes are common and it doesn't cost anything to the company. Treat...
Many companies don't disclose salaries when advertising for positions. They usually say DOQ, DOE, etc. Your qualification or experience means very little. They want to know what you are making now so they can offer you a bit more.
Some companies have known salary ranges for various levels of...
