Thanks everybody for participating, the Clark Dietrich website has a lot of information, haven't checked it all yet. Also the CSSBI book is very helpful, but i was also looking for information on how to "configure" these buildings, like how to globally design the structure (determine which walls...

Yes, cold-formed light steel framing, especially for residential and low-rise (up to 4 or 5 story buildings).

I am from Nicaragua, today i joined a construction group on social media and saw somebody offering to build homes with "light steel framing", looking closely at the pictures i saw regular drywall studs for the walls, is this allowed?. I am new to Light Steel Framing (LSF) or timber framing for...

Has anyone used ETABS for light steel framing design? Do you recommend a different software for this structural system? Thanks in advance.

Thank you. Instead of modifying the properties, could it be the same if we use different wall thicknesses?, i.e. the Masonry design code for Dominican Republic includes a table where they give you "equivalent" wall thicknesses according to the spacing of the rebar (assuming only the rebar cells...

Hi everyone, i was working on modeling a masonry structure in ETABS 2015 and i wondered if ETABS always considers the wall to be fully grouted?. If a partially grouted wall be needed, what would be the best way to model it?. Thanks in advance.

Thank you TXStructural for your response, i believe in my case ductility is very critical since the masonry walls do not contain any steel and the confining elements provide the ductility for the wall, the main supplier for the A496 (now A1064) wires in Nicaragua is advertising it's product...

Sorry, here are the links to the documents, they are free to download. http://www.preventionweb.net/files/2732_ConfinedMasonry14Dec07.pdf http://www.confinedmasonry.org/wp-content/uploads/2009/09/ConfinedMasonryDesignGuide82011.pdf

hokie66, here are a couple of documents that explains what "confined masonry" (CM) is, personally, i don't like this construction system, when building with masonry, reinforced masonry is the way to go, but, CM is the most used in Nicaragua, i'll say almost exclusively, and not even done right...

Can A496 bars be used instead of A615 rebars?, ACI 318 limits the deformed bars specifications to A615, A706, A995, A996 (Sec. 3.5.3.1) and A1035 (Sec. 3.5.3.3). Here in Nicaragua the masonry construction method used is "confined masonry", concrete elements are usually 6"x6" and these A496 bars...

I am in Nicaragua, Central America, we are working on the San Jacinto Geothermal Power Project. It is a private job.

The Coal Tar Epoxy is what the engineering company specified on the drawings, by the way it is Carboline Bitumastic 300 M. Thanks for all the comments.

Thanks for the comments. After speaking over the phone with the manufacturer technical assistance department, these are the answers i got: 1.- Muriatic acid is not recommended because it will not create the profile needed for the coating to properly adhere to the concrete, besides it creates...

Hi, We need to use a Coal Tar Epoxy Coating to coat a cooling tower on a Geothermal Power Plant, the spec says we must cure the concrete for 28 days at 75°F (24°C) and 50% relative humidity. The weather here is very hot at this time of the year, around 34°C (93°F) and sometimes hotter, at night...
