Explore the intricate details of sheet S401, focusing on the beam schedule, sections, and details, including width, depth, reinforcing, and remarks. Delve deeper into the specifics of beam diagrams, rebar extension, stirrup schedules, vertical beam penetration detail, and various types of stirrups.
Key Insights
- The beam schedule provides essential data such as the mark, width in inches, depth, reinforcing, bottom bars, stirrups, and remarks. It serves as a comprehensive guide to understanding the construction and design of a beam.
- Details relating to rebar extension in columns, stirrup schedules, and vertical beam penetration are carefully illustrated to provide a thorough understanding of the structural requirements and specifications in construction.
- The document further breaks down different types of stirrups - type S and type D, explaining their placement, clearance requirements and the role they play in maintaining structural integrity.
Note: These materials offer prospective students a preview of how our classes are structured. Students enrolled in this course will receive access to the full set of materials, including video lectures, project-based assignments, and instructor feedback.
Let's spend some time reviewing sheet S401, the beam schedule, sections and details. Let's begin looking at the beam schedule. You can see in the beam schedule, there's the mark, the width in inches, the depth, the reinforcing, where bottom bars are and how many, top left, if need be, top right, stirrups, which are cages, and we'll learn more about that, and there are remarks.
So here is a typical beam diagram. You can see that this is a column under a structural grid, column at a structural grid, another column at a structural grid, and a projection, for example, like a balcony. Between the face of the columns, there's a length.
This is showing that the rebar coming out of the column must extend a quarter of the length into the beam. There's rebar here against this column, 0.3 times the length of this. On an interior, we have 0.3 times the length, 0.3 times the length.
You can see we have a class B lap, and then we have a length right here. There's a schedule for the stirrups that go from here into here, and we'll see the stirrups down here. An interior span, scheduled stirrups, and scheduled stirrups for a cantilever.
The typical vertical beam penetration detail, you can see that we're saying at 8-inch diameter, sleeves are larger, provide two J-hook bars at 6 inches on center each side of sleeve, centered about sleeve, match bar size of typical beam stirrups. So that's what's going on in here, and they're saying three additional stirrups at 3 inches each side of sleeve, match size of beam stirrups. Then they have their note that's going on right here.

There are three different types of stirrups. There's a type S stirrup, where we have the floor, a beam, the floor continues. We have an end condition, and then we have a much broader type D stirrup.
So you can see they're talking about the clearance requirements from the edge of the beam to the rebar. Typical stirrups at the sides. And by a stirrup, we're looking at this guy coming up and over, down, up, and down.
It's going around this rebar right here. And then we have this coming over and coming down. So you'll notice this comes straight down.
At the end condition over here, it comes in. If we look at the detail over here, detail at ramp. Again, you can see we have a beam down here.
You can see how the reinforcing bars are coming in through here and the standard hooks at the end of this ramp beam. Here we have a section through a ramp. We have coming up and over, a class B lap.
You can see a curb here at the edge, six inches horizontally and vertically. There are callouts for the rebar and widths of the wall. There's a ramp concrete beam schedule.
There's the mark, the width, the depth, the kind of reinforcing, and information about the U-bars. And these conditions here would be called the U-bars. So here it continues up over to there.
Pan down to this detail, detail at ramp slab. You see the dimensions. You see the callouts for top and bottom, the size, and the hook around the beam.
You see essentially the cage that's going on here. Once again, a class B lap. We have it here.
And you can see that there's a pour joint because this system here would be poured separately from this system here. Here we have a trench drain. And you can again see the rebar.
It talks about the spacing on either side of the trench drain. It's talking about waterproofing on the bottoms and sides of the trench drain. And they're saying, see ramp detail for reinforcing.
Go to image eight on page S401 for additional information. So that would be over here. So again, we have three quarter of an inch detail, three quarter of an inch detail.
These details are drawn to scale. Detail at ramp slab, again, drawn to scale. We have the conditions happening here.
See architecture for information about the trench drain. Distance from edge of footing to edge of trench drain. This is the expansion joint.
And it's saying go to details eight and nine on this page for more information. So again, nice information presented. Most of these details, at least these down here, are drawn to scale.
The rest of these are not to scale. So again, please enjoy this drawing, and I'll see you in our next video.
