Thanks averyone, if someone has different opinion it's welcome.
@JohnRwals, all bars are almost at their full tension unfortunately, 2 bars are not enough.
I will let you know if the designer has a different opinion, a justified one, when he replies my report, I don't see this happening...
Hi everyone!
I am reviewing a retrofit project where I found a connection detail I have never seen before, I have serious doubts that this can work.
There is concrete overhang beam which is partially interrupted by a circular HSS column, the beam top bars, which are working at full capacity...
Hi everyone!
I am designing some steel latticed structures for an electrical substation using ASCE 10-15.
I have some pretty dumb doubt. The specification dosen´t show any load combinations and I can't find any resistance factors neither. It does however mention "Desing-factored loads"in 2.2...
Hi all,
I've been asked to design a stone masonry gravity retaining wall (rocks + mortar) 9.6 feet tall.
I know EN 1996 (Eurocode) covers stone masonry, is there any American code for this?
Thanks!

Hi everyone,
I am working on a timber structure, first time dealing with timber. All my design are based on AWC-NDS 2018. I am dealing with a 3 ply 2"x8" SYP single span pinned beam. Total beam length is 12ft subject to 60 plf wind load. In order to control deflection and strength I need the...
Hi all!, I am designing an industrial platform wich supports a hoist, see attached image. As the columns supoprting de runways are quite long I am concerned with the vibration of the structure. Does anyone have some recomendation or reference of what minimum natural frecuency should the...
Hi all!

BAretired, thank you so much!! that is exactly what I was needing! really helpful!!
dnlv, thanks for the tips I haven't finished reading APA's document yet, maybe i'll come back later on your suggestions! I was supposing all lateral forces (parallel to the plane of the A frames) go through the...
BAretired, yes, inside face of rafters do get compressed by flexure but bending moments on this direction are lower allowing for larger unbraced lengths.
Anyone has recommendations on how to nail down and connect plywood sheeting to each other and to rafters to assure right performance as...
Thanks Nor Cal SE! Regarding the 1st question, it think i wasn't clear enough, i was actually concerned about wind perpendicular to the plane of the A's. In this case i am trying to determine if the plywood sheeting could take the load or if i braces on the inclined plane of the rafters are...
Hello everyone,
I'm assessing a friend of mine who is an architect who is working on a project of an A-Frame cabin as in the attached picture, he is using some drawings and references form some do it yourself books and asked me to check the designs. I don´t have much experience on wood design...
