Create a Structural Composite Floor with Metal Deck Profile in Revit

hi guys nyle here come back to the 80/20 BIM Channel today we're going to talk about can create and model a structural composite slab floor in revs complete with a profiled metal deck as you can see in the example here the video contents are going to consist of generating your profile from scratch your profile family from scratch using a card detail as a base and then bringing that into our live projects to develop the actual floor itself the slab the composite slab itself complete with the deck to the underside of us and then finally a little to known trick the tip that people and don't realize is present in the floor and modeling functions on how to control cantilevers so that your steel and your concrete can actually have different extents on the boundary conditions so that further adue give me one moment and I'll be back to you and we'll get started so the first thing we need to do is generate our structural profile family that will represent the comm floor 60 profile that we'll be using as the structural deck within our compass at floor system so in order to do this we go to file or the Big River button depending on what way you have it set up and on the drop-down then we're going to go to new family and I'm using the UK metric library you may be using a different mark library and but for the most part they should be similar to this and what we're going to do is select metric profile now that we're in our metric profile family what we need to do is actually generate our proposed deck profile and we need to generate one segment that we know is going to repeat consistently down this section of the floor so the way we actually create the profile lines themselves is via the line tool here and there's two ways that you can do this you can do this if you want to create a generic profile that you you know yourself you could merely draft it in so you can do something akin to this and what you'd have there is a very very basic profile deck so let's say you're not sure what type of deck you're going to specify in the early project stages but you still want to represent something for provisional details let's say at a pricing stage you could quickly draft in something similar to what I have here and save as name is whatever profile that you want and use it in your ever profile for your comps of floor systems but in this instance we're going to show you preferred method and what I like to do is typically manufacturers have your card details available they still haven't caught your push and Revit families but they normally have card details available so what I normally do is I go and find the manufacturer specific profile that I'm after and I used US within the family as the basis that we draft over so in order to do that we go to our insert tab import cut and then we navigate to the floor profile that we've derived from the manufacturer in cod4 okay I'm gonna put it in current for you only color isn't on a preserve positioning I'm not gonna worry too much about that for the moment correct lines everything else is okay import units Auto detect now you can see there are come 460 profiles out to snapping over here okay so what we're gonna do is I'm going to take this element here I'm going to select the midpoint of the repeating detail those they've shown us and I'm gonna put us with the midpoint with the intersection apologies I forgot to unpin owes a lot of my gracious to the intersection of the reference planes here so we know where the center overs is now going again to create the actual lines for the family we go into our line tool and now we can select pick lines but the first thing we want to do was under subcategory we want to change in the family profiles apologies we want to change the profile usage too you slab metal deck and that's telling the family that this is going to be a slab metal deck profile and not similar profile variant throughout the project okay so then I'm gonna go to our Creator we're gonna press line and we're going to press the pick line tools here okay and when we highlight just one line segment of the card file we can press tab and you can see that nearly the entire thing is selected in a chain okay so I'm going to select that and what that's doing there is that's generating our lines over the card data now what you see here is there was some sort of missing connection between the card drawing here so again I'm going to go to create I'm going to go to line I'm gonna use the pick lines but then I'm just gonna pick the single lines in isolation here and I missed one of them there which I taught it is so lying again pick lines no this is as straightforward as it is to create the come floor profile deck family okay so now I can go into this isn't the link in fact it's a it's it's a an import so I can select the card data and I can merely delete it away and what we're left with is there a repeating come floor detail so this is the comm floor sixty so what we're gonna do is we're gonna go sick file save as family we're gonna decimate location I'm just going to leave us on desktop Lamont and I'm gonna Carlos come floor sixty profile unsafe and now I'm going to notice into the projects and it's loaded into the open project that I had in the background okay you can also bring your family into the Revit environments into your project environment but going to your insert tab load family and navigate to wherever you have saved those your new profile so now that we've generated our profile what we need to do is actually generate the structural floor slab so that we can append the profile to the underside of us so in this model here if I turn off the section box temporarily you see that we actually have a portal frame design but we have a mezzanine internally that's kind of the halfway height level and what I want to do is I want to actually put the composite slab across this level here okay so we're gonna migrate to the view Association stuff and the plan view associated to that is mezzanine top of Steel camera going to go to our structural tab we're going to select floor structural and we're gonna draw a boundary so I'm not gonna be too pushed about the boundary for the moment I'm merely going to click and drag like that for the moment okay no one's gonna bring out some of the snaps to the extremities of the steel now bearing in mind if you have more time yourself you'll be going in and out around your columns to my knowledge your details are so this is the boundary for our floor okay and you can see that because we're at our mezzanine top steel level on the right hand side in the project browser the level that the floor is all Rotta matically been generated us is the mezzanine top of Steel level okay the floor at the moment is called generic 300 mil you can see that we have previous examples present in this model but I'm not going to use those for this instance I'm gonna go with the generic okay so we've got a generic 300 mil floor and we have a top of steel TOS okay the mezzanine top of steel so what I actually want in total is a 150 mil deep slab on a comp floor 60 so I'm gonna set my offset for the top of the slab to be the mezzanine top steel level plus 150 mil to account for the full depth of the build up of our composite deck now thus we have designated some of the properties to start with what we need to do is ensure our spawn Direction is moving in the right way okay so using this tool here to spawn direction we can pick a boundary and our our floor will span parallel to the boundary that we select for the span direction okay so the previous iteration was correct because we have the short span of the beams in this direction I want to set the floor to span across the short distances of the beams so our floor is going to span left to right now so we're going to finish the edit mode on the floor and we've generated a structural floor slab to begin but this is without the presence of the structural deck and it's incorrectly sized at the moment its depth is too great so snapping back to the 3d view you'll see this we're actually going down into the depth of our members which we don't want so we're going to select our generic floor again we're going to press edit type and we're going to duplicate and we're going to call us 150 mil consus apologies come to the slab con floor 60 deck okay and now we're going to go under construction to the Edit tools do you're gonna see that we have structure here as the only and I see as the only material item assembly item within the actual structure of the floor so first I'm gonna do is we're gonna designation a concrete for our build up so I'm gonna say concrete cast in place and I'm gonna set the thickness disaster to 150 mm okay so now we have 150 ml total build up okay but what we also want to do is insert another assembly item so I want to insert okay and you can see this automatically went to both so I'm going to move my new inserted item below the country because we want to concrete to be to the top and the deck to be on the bottom okay then under the structure drop down we're gonna drop down to structural deck and you'll see that we are prompted here with the various come for variations and you start to see the repeating profile presence in the you once it's opened okay so I'm going to scroll down and you can see that we have multiple come floor variants here we have the Coruscant floor and we got the roof decks and so on okay we have a standalone deck or bound by the layer of both if you are leaving the material present then you want to leave bound by arrabal okay so in this instance we're gonna scroll down we're gonna select come floor 70 and we're going to press the material and we can select whatever we want here so in this instance I'm going to say calve I'll just put in steel and see what we have here okay I'm not gonna get too concerned about that for the moment I'm just going to use this steel for the moment okay Midd you're going to use the galvanized steel and now that we have done all of that we can press ok and yet again all the rest of this information is okay it's nice and we don't need any additional so I can press ok and now you'll see that what the floor depth has decreased so obviously we're still going to our columns where we haven't cut out the the floor direction from the columns but generally you can see that the flora depth is correct so now go back to mezzanine top of steel level and I generate a section through you can now see that because we've generated a section across the span direction you can now say each and every member of the profile repeat so we Helen II have a profile that has two sides down the centerline but you can see it repeating across the entire deck okay there is another thing that is worth noting and a gun combat here in a moment to show you how it functions but basically you can control the cantilever and the offset steal from the boundaries the tool set okay so I've come stop recording I'm gonna come back into you in just a moment on that okay guys a back with you and you can see here is us I've went back into the plan view and I've created this intersection mark here okay and on the right hand side you can see how that section is interfacing and with the geometry adjacent okay so what you're seeing here is the slab expanding onto the very very outer edge of the beam okay and what we actually have is we have a void between the slab and the inside face of the cladding rail that we want to infill but we also don't want our structural deck to carry out as far as the cantilever actually what we want to do is we want to reduce it so it's landing just centrally on the grid line so what we have here is that you can see on top I've got two dimensions on top here that we need to control the cantilever around the boundary with so how do we extend the concrete in isolation but actually retract how far the structural deck protrudes as has extruded down the length of the composite the composite slab and there is a tool that's now built into the structural floor system okay so when you select it in plan you can press edit boundary and when you select a boundary line that you want okay once you'll see is just actually up just underneath the top toolbar there's a new tool setup pops up and it gives you offset values a defined slope well more importantly it has cantilevers and has a concrete cantilever and has a steel cantilever okay what we're gonna do is we're gonna manipulate these values so that they report too much the dimensions that we have here and what you'll see is that our steel should trace back to join the grid line and our concrete should extend out to the back face of our cladding resum so I'm gonna change that value 258 and I'm gonna change that my value to minus 77 now I may have to the plus and minuses backwards here I'm not sure okay but I'm gonna press ok there and you can see that I actually importers incorrectly all right and the reason I am put it incorrectly is it actually matters which part of the building this section is code true so because we're on the left-hand sides those values should have been reversed so if I control Z if I go back here sorry into the plan view edit boundary and I slacked up boundary again and I put the minus in front of the concrete and leave the steel as a plus value press ok now you'll see that we have a concrete cantilever that extends independently of the structural deck that the structural deck is traced back from the edge of the beam it was resting on to the midpoint of the beam and at our concrete for the overall slab has carried out in a cantilever independently so that's just a tip that very few people are aware of within the structural flooring systems in Revit so thus pretty much concludes the tutorial on how to create a composite floor system inclusive of a structural deck within Revit if you have any questions on this Val please let me know in the comment section below make sure to LIKE comment and subscribe as always if there's anything that is absent from this tutorial that you'd like to go through and a little bit more detail by all means let me know and we can run through and just one closing note for you to be aware of you cannot present the profile in 3d view and Revit as a default so it doesn't matter that you have the profile present in the model it's too demanding on the its to graphically demanding on the program to render the profile repeating underneath a whole slab so as a default it doesn't allow you to do that so if you need this methods to produce 3d renderings to the underside of the slab for any reason itself it's not sufficient what you're gonna have to use is something like a facial profile hack or something like that that you that you array down the underside of the slab and it carries through so that's just another thing to be aware of before you finished and other than us I think we're all set here and done and as always thank you for checking out the h20 p.m. channel and we'll talk to you again thanks take care bye bye
