Overview

The programmatic functions of the interior spaces are organized around the structural system that provides the framework for the building envelope and the finishes that define the edges of these interior spaces, the walls including the floors and the ceilings.

Interior spaces span the distance from one side of the room to the other. A structural system must be designed to safely achieve the spans and distances that support a column bay of the case study, supporting the program, the users and all the loads within the space supported by the floor that sits on the structural spans. The selection of a structural element is a process of assessing the pros and cons of the possible variations, their properties, and the size and shape each material is fabricated into, to serve as an economical structural element.

This assignment combines the development of a three dimensional representation of the selected floor(s) of the case study building and the application of a system(s) of structure to span across one or more spaces making a deck for a roof or a floor above the space. Each structural element must be sized using simple structures. The full system will be documented as an axon and a section drawing depicting each of the elements of the system. All elements are to be dimensioned, labeled, and annoted with details including the span dimensions for the referenced structural system.

1) Identifying the structural elements for the steel construction system:

2) Section Drawing –

  • Option – Exploded Structural Section:

3) Axon Drawing of the Structural Bay:

Due Date(s)

Final Module 3 drawings will be due Friday, before the final pin-up.

Instructions

Apply the reading materials to help build a deeper understanding of the concepts discussed in the text, through the development of the calculations and drawings.

NOTE: All drawings will be on 11″x17″ sheets at scale listed below unless otherwise agreed with Professor.

Final Deliverables:

  • Calculations and Annotations (all lettering to be 1/8″ high)
  • Section Drawing at 3″ = 1′-0″ scale
  • Structural Bay Axon at 1/4″ = 1′-0″ scale

Following these steps:

  1. Sketch the configurations for the structural system from the case study floor plan.
  2. Select one configuration and work through the calculations using the simple rules of thumb for each structural element.
  3. Draw each element of the structural section in section with dimensional annotation for the depth and width.
  4. Lay out reference lines for the axon detail starting with the structural grid lines and primary guide lines.
  5. Using guidelines, indicate vertical structural elements (15′ tall, 18″ square or diameter)
  6. Working in the sequence of construction, lay out each layer of element using the peel away strategy to show each layer clearly (see mock up above).
  7. Review the axon and add line weights and annotate each element of the structural system. See lettering guide here.
  8. Add dimensional strings to the column grids and elevations.
  9. Complete each drawing. Scan using CamScanner app or flatbed scanner and format file naming convention per guidelines (use submit on onedrive or email Professor).
