Understanding Structural Drawings in Building Design: A Detailed Overview

Exploring the Detailed Structural Grid System and Framing in Architectural Drawings

Discover how structural drawings are used to communicate intricate details and enable seamless collaboration among various teams working on a building project. Learn how different elements such as structural grid systems, detail references, legends, and publication schedules are incorporated in structural drawings to depict a clear picture of the building's design.

Key Insights

  • Structural drawings effectively illustrate the building's design using a structural grid system, which runs from 1 to 8 along the top and from A to H along the side. This system allows easy communication about the location of information within the building.
  • Different elements such as legends, roof structure notes and publication schedules are incorporated in the drawings. Legends give more information on specific details within the structure notes whereas publication schedules guide on how to build certain structures within the building.
  • The method of presenting information in structural drawings is quite common and involves detailing that often refers to other details within the set of drawings. This approach makes it easy to trace information and understand the design better.

If we continue to the next page, we are in the plane of the roof structure. When you look at the drawing once again, you see the structural grid system. From 1 to 8 along the top.

From A to H along the side. Again, this allows us to easily communicate with other people, regarding the location of the information within the building. Look again and you will see that we have the references in detail.

Again, if I zoom in on this area. You can see the detail 1 on the sheet, S 5.1 that will represent the slit right here in the building. And the first time we see it is on page S 3.1. You will notice that some of this information is showing a plot or pattern.

If you remember, the roof of this house is a roof with cherry armor. So, this indicates that we have a frame filler. So, again, we have standard trusses that are used in the building, but we fill in between the trusses.

To allow the roof to present itself appropriately. In the upper right part, I see that I have legends. I have my roof structure notes, and as before, instead of including all the text within the structure notes themselves, I say that to get more information about this, check this detail here.

I also have a publication schedule. You will see that it is called P 1, 2, 3. And for example, if I look at this area and here, I am seeing different types of posts, structures and in the list itself. We are informing people how to build the posts properly.

Not all posts are considered 4 × 4 or 6 × 6. Sometimes we have to do them. I go to the next page. I am showing details of the foundation.

Again, if I zoom in on this detail, you can see that there is a detail that we are seeing here. But this detail refers to other details within the set of drawings. If I look to the left, I see that in this image, I am showing a section.

So I have the section cut, A, diagonal, A. And if I look down here in the detail, I am getting a better presentation of what that sliced section looks like. So again, here is a detail that refers to another detail within that drawing. In this image below, the same is happening.

I have a section cut. And for more information about this specific frame, I look at section A, diagonal, A. So, this is a way of communicating information within a set of drawings, is relatively frequent. I go to the next page and once again, I'm looking at the ceiling frame.

If I zoom in here, you can see again details that refer to other details. And again, we have a note, I follow the reference line and point exactly where that information is going. So, this method of presenting information is very common within the structural drawings themselves.

Nuestra siguiente página es información adicional de enmarcado. Esto es relativamente sencillo, de nuevo, detalles con otros detalles a los que se hace referencia en ellos. Y nuestra última página es de nuevo información de enmarcado más estructural.

Espero que esta descripción general de los dibujos estructurales haya sido útil. Espero trabajar contigo en nuestros dibujos, M, E, P. Nos vemos en el siguiente video.
