Delve into the complexities of a Level 2 Hotel Framing and Reinforcing Plan for a building's structural integrity, and discover the purpose and arrangement of reinforcing bars inside the concrete. Explore the structural details such as the expansion joint, nominal slab elevation, and rebar configuration that contribute to the building's stability and seismic resilience.
Key Insights
- The Level 2 Hotel Framing and Reinforcing Plan contains crucial details such as the top of the nominal slab elevation being 54 feet and the use of an 8-inch-thick flat slab post-tension system north of the expansion joint.
- The plan includes information about the reinforcing bars inside the concrete, their direction, size, and configuration. These bars, also known as rebar, play a vital role in enhancing the structural integrity of the building.
- An important feature of the building design is the 4-inch expansion joint between the left and right side of the building. This feature allows the building to 'float' during seismic activities, enhancing its resilience against potential damage.

Let's review page S105B, which is the Level 2 Hotel Framing and Reinforcing Plan for Part B of the building. If we zoom down into here, we will see notes that the top of the nominal slab elevation is 54 feet. Structural concrete slab is an 8-inch thick flat slab post-tension system north of expansion joint unless noted otherwise.
And then it says look at page S102A for additional notes. For the most part, what you're seeing here is information about the reinforcing bars that are inside the concrete. So you can see the direction that they're going and the size of the reinforcing bars.
There's a 4-inch expansion joint between the left and the right side of the building. So this is essentially where we have two independent buildings. There is a space between the two buildings.
It allows the building to float seismically. And then this expansion joint is covered with metal. You can see the match line for parts A and B of the building.
References to details. References to sections. It's showing here that the rebar comes out and turns back.

It just doesn't end. There's a physical turn to it. Again, more detail references.
Some note references. Again, you can see how they're dealing with the rebar here in the elevator hallway. Call-outs of rebar.
That's for this going up here in this direction. This is the extents of how long that rebar configuration exists. You can see that it extends 9 feet below the bottom edge of the elevator shaft.
Detail referencing. Noting about spacing the bars, the reinforcing bars at this location. The call-out that this is a shear wall.
And you'll also note that all of the structural grids are shown. And dimensioning to those grids is reflected on this drawing. A very good informative page with a lot of referencing to other details.
Again, this is primarily a sheet that shows information about the reinforcing bars that are inside this thick 8-inch slab. So once again, enjoy reviewing the drawing, and we'll get together in our next video.
