I still need to know what ASCE 7-16 says for deck loading. I know the ICC committee for 2018 IBC has rejected the proposal to raise deck and balcony loading to 1.5 times the load of the area serviced. They are keeping the 2018 IBC and 2018 IRC requirement at the same as the area serviced. The...
Can someone who has a review and comment copy of ASCE 7-16 tell me whether the requirement in Table 4-1 that decks and balconies be designed to 1.5 times the live load for the served area has been changed. The state of Washington issued an amendment to the 2015 IBC raising the live load for...
Mike,
You know architects don't always get what they want. I'm waiting to see your detail. I work with a lot of professional deck builders and I've never seen a detail through brick veneer without posts next to the wall that I like.
Here is some basic info on AWPA use categories and types of preservatives currently approved for use in USA.

According to IHS MS35338 was cancelled in 1996 and replaced with Aerospace standard NASM35338. It is a direct replacement. The M is for zinc plated. I can't give you the copy from IHS due to copyright but it should be available.
Correction. I hit a wrong key on my calculator. Your log girder is very overstressed if you have a 19 ft tributary width acting on the girder. I knew something didn't seem right.
From the pictures it looks to me like a round log flatted top and bottom which is not unusual for log homes that I work with. Although unusual I have seen a log girder split/check vertically top to bottom along about half it's length in a log home after an earthquake. As Mike said, check for...
I mentor a lot of young engineers in my job. Don't be afraid to ask your boss questions and learn from him/her the specifics of what you are to do. Develope that line of communication. It is important. Don't expect them to give you the final answer and do the work for you but do ask questions.
"Structural Engineer in let's say Washington? Washington requires an SE for structures essentially classified as III and IV."
Don't forget local restrictions also. I'm licensed as a Civil PE in Washington but do a lot of residential structures. I can't do any structural engineering in the...
There are a lot of parameters you have to put in before you can use the unity check option. Go to Bentley's web site and download the STAAD V8i Technical Reference Manual. Section 2.14 will lead you through all the parameters you will need to enter...
It goes back to (V*Q)/(I*t). On an I beam strong axis the large area creating low shear stress in the flanges so (V*Q)/(I*t) is very close to V/d*tweb. On the weak axis the web is at the neutral axis and is ignored. Q/(I*t) is equivalent to 1.5/(2*b*t) of the area so V/(2/3*Aflange*2)...
KIRO news from Seattle just had a Washington DOT representative state an over height vehicle struck the bridge and caused it to collapse. Well see if that story hold up.
It's normal to design a 4 point lift to only use 2 legs unless you have a specific method of equalizing the load. Sometimes I will model a third leg going to one corner and then show there is no load in that leg from the results. For rotation about Y I would restrain one corner in x and one in...
ASCE 7-10 refers to storage racks being designed to ANSI/RMI HM 16.1 which is put out my the Material Handling Association. I haven't seen the document but it may be a good place to start [glasses]
I have my current position because I gained a lot of knowledge from my outside work I would never have gained from my normal job. My bosses know my broad background and bring things to me that are out of the norm and other engineers don't have the broad background for. It depends on your job...
I've been doing engineering as a side business since about 1990. I carry $250,000 per project professional liability through ASCE (American Society of Civil Engineers). I do residential and log home engineering and tell my clients up front it is my side business and what the time frame is. If...
ASCE offers professional liability insurance program specifically designed for people who are already covered under their regular job and do work on the side. It is reasonably priced. I have used it for years. Even when you add in the ASCE annual membership dues it is far less than anything...
...was conservative and put the stiffeners at 60" oc. The problem comes in sizing the stiffeners per 3.5.4.3.
The stiffener sizing equation is
I>1.2*(h^3)*(t^3)/(a^2)
where h=Web height (108")
t= web thickness (3/4")
a= spacing of transverse stiffeners (actual?)
I= Minimum Moment of...
