Videos related to the steel reinforced concrete construction industry. Concrete Reinforcing Steel Institute (CRSI) is the authoritative resource for steel reinforced concrete information. CRSI authors many industry-trusted technical publications and standards documents; and whose members include rebar producers, fabricators, placers, accessory manufacturers and suppliers, and design/construction professionals.

Stay away from bridge decks if you can hamstrings will hate you at the end of the day haha. loved being an apprentice on bridge decks because we carried it all out the JIWs had to do the 50% tying haha
This code has been created to protect public health and safety for everybody. The changes are a response to developments in materials structural systems and seismic design. Chapter 10 defines the limits for reinforcement of compression members. Great video.
Rebar being tied in my understanding is only to hold bars in place before they're reinforced by concrete, I'll be starting my ironworking career next week
@@flacko001with the company I work with, hell. I work with my dad and brother and they Don't take it easy on my at all, you're outside working in the elements, packing a lot of weight while getting bitched at for not loving fast enough, I'm starting to really enjoy it now but at first it sucks
Gentleman, you can't introduce any heat to the Rebar. It will weaken the strength of the Rebar. That's why you don't tack weld intersections. Tie Wire is a sufficient means.
Thank you. I live in the Malaysia and I'm currently doing a residential project using reinforced concrete. We are under Restricted Movement Order (RMO) due to Covid-19. I was worried about this as the RMO started when I was about to fill the first floor with concrete and the site has stopped for a month now. The formwork and Rebars are all exposed to the elements which got me really worried about the effect it has. After watching this, I'm more assured that it actually increases the bond of the bar to the concrete. I measured a 6% nominal weight deterioration for a 10mm bar would be 9.7mm. That's a low margin. I will check the bar size once the RMO is lifted.
Jerry Hubbard did they have a reason? normally the smaller the bar the more ties we put on it, but the 32mm bars we normally put a few ties on a 6m length.
Back in the day, everything relating to nuclear was overdone or engineered. I guess they took no chances that it was being done right. Even the # 18 bars were tied at every joint with 9 gauge wire. The outside retaining wall, 4 feet thick, 400 feet in circumference had 60 % steel in the concrete. Some of the steel was so tight the entire pour and slip form had to be cleaned after all the re-bar was installed. If anyone was caught throwing anything in the form before pouring including spitting, you were fired on the spot. They took this stuff seriously.
Jerry Hubbard thanks for the reply, sounds like a good job to have been involved it. did you use a high flow concrete to help get around the steel congestion? i bet u guys had to make sure u caught all ur wire cut offs to
believe it or not, the concrete was poured at no more than a 4-inch slump. They used 2-inch vibrators and plenty of them to get the concrete in place. All concrete poured in an area they called safety related, which meant it was anywhere around the containment building had to be 5000 psi. The concrete poured inside that reactor building that the steam generators and the vessel itself were a 9000 psi concrete. It had steel pellets in it. As far as cutoff wire, before the concrete was poured, the labor force would come in with water and air jet hoses and clean out anything that fell into the formwork. At the bottom of all the forms were clean out holes. NO cut off wire was left in the pour. It was hard work especially in the summer here in South Carolina.
Jerry Hubbard i would have loved to be on that job, concrete construction is my favourite job. ive been formworking for 13 years now. my trade has taken me to every state in australia i have done the same process with clean out holes and air hoses aswell,
Does someone know the double loop tie wire? It's for tying rebar too.And it's convenient and stable. Please contact me Wechat/Whatsapp: +86 13820324169
