Assignment #4: Structural framing, steel

Assigned Oct. 18, 2006
Due: Oct. 30, 2006 (discussion sections: find your room and time)


section Not a group project. Each student must do project individually.

Problem statement:
Submit an axonometric, isometric, or perspective drawing of a hypothetical building framed in steel as shown in the wall section to the right. Label all elements identified in the section using a numbered key or words and arrows.

The point of the drawing is to graphically show, as clearly as possible, the way in which all the parts of a typical steel-framed building fit together. In order to show all the relevant connections and the full three-dimensional complexity of such a structure, it will be necessary to cut-away, or "explode" the drawing to reveal things that would otherwise be obscure. Some examples of cut-away and exploded isometric and axonometric drawings are shown online. Additional images can be found within the ARCH 262/562 archives (Assign #2, Fall 2005)

Additional requirements:
Note that the building's cladding and suspended ceiling are represented in a generic and schematic way: for this assignment, do not attempt to represent these elements in a more realistic manner, but instead simply show them as they appear in the section. The cladding can be shown as being attached to the spandrel girder or slab by clip angles approximately 4'-0" on center.

The foundation consists of a continuous foundation wall and footing directly under the cladding. In addition, columns rest on 1'-0" square piers on 2'-0" square footings, overlapping the continuous footing of the wall as shown in the section. Steel beams can be assumed to be spaced 6' - 12' on center. While it is only necessary to show one column, it is recommended that at least two beams be drawn in order to clearly indicate how the corrugated steel deck is supported.

The column enclosure hides the column within the occupied space, but not above the suspended ceiling. It can be represented schematically as a thin surface (such as 1/2" gypsum board) with or without metal studs to support it. The HVAC unit enclosure shown in the section can be assumed to be continuous between column enclosures; it is not necessary to indicate any of the actual HVAC equipment, fans, or pipes within this thin sheet metal enclosure.

The scale of the drawing should not be indicated, and no dimensions should appear. However, all elements should be drawn to scale. For non-perspective renderings, a drawing scale of from 3/4"=1'-0" to 1-1/2"=1'-0" is probably a good place to start (the section shown here was initially drawn at 1"=1'-0").

Format:
Drawing may be done in any legible medium, and may be constructed freehand (over hardline base), hardline, or using modeling software. Final drawing may be drawn or reduced to 8-1/2" x 11" if it remains legible; maximum size is 11" x 17". Drawings must be flat -- do not roll up.

Academic Integrity:
"Course Assignments. Students are encouraged to discuss the content of a course among themselves and to help each other to master it, but no student should receive help in doing a course assignment that is meant to test what he or she can do without help from others. Representing another's work as one's own is plagiarism and a violation of this Code. If materials are taken from published sources the student must clearly and completely cite the source of such materials."
