elements would be located and what type of system is to be used, along with a very brief
narrative (bullets) indicating the relative advantages and disadvantage of each of these
For the alternative lateral load-resisting systems, you might consider moment-resisting
frames, braced frames, shear walls, and so on.
In discussing the possible alternatives,
various issues will need to be considered, including economics, strength, stiffness,
redundancy, overall torsional resistance, and possible interference with interior floor
spaces or views.
In carrying out this assignment, you should consider or comment on issues such as:
If you consider a moment-resisting frame, where will the moment-resisting
connections be located (i.e., in all frames in both directions, only in perimeter
frames, in all or only some (one?) bays around the perimeter, one or more interior
core frames, etc)?
What spacing of exterior columns will you use (e.g., you might
alter the column spacing along the perimeter of the building while retaining the 30-
ft. module on the interior)?
In the original 1994 design, two perimeter moment
frames, each with three bays, were used in both principal directions of the building.
