Spring semester only T Th 2:30 – 3:45 p.m., Anderson Hall, Room 117
The second course in the Building Technology sequence, Complex Primary Systems 02, completes the first year of materials and assemblies. The course operates as an extension of the first-semester course Geometry and Primary Systems 01 building on the introduction to geometry, digital modeling, fabrication, and material form in order to investigate nonstandard or complex building systems. 
This investigation into complex systems begins with concrete. As a rigid system and a liquid material, it operates uniquely as a rigid, monolithic structure. As established in the first course, the system will be introduced first historically in the way we have used and continue to use concrete as a building material in architecture. Following the standard systems lecture, a complex concrete construction lecture will present non-standard uses of concrete looking at precast and tilt-up as well as complex geometries through the work of SANAA and Toyo Ito. The lectures will address issues of production, manufacturing, sustainability, and rule of thumb sizing of concrete systems. After the systems lecture, the associated contingent systems will be introduced through a lecture format. The investigation of the system will be furthered through a field trip to a nearby concrete construction site and a two-part assignment which will require the basic sizing of members, drawing the system and connections as well as how the system connects to its contingent systems. 
This format is repeated through the course as we transition from concrete to shells, monocoques, tensile. Pneumatic, and diagrid systems, all of which carry loads through surface or envelope. Following spring recess, the course shifts towards non-standard systems such as long spans and high rises, which often require a unique approach both materially and structurally. 
This is the second of four required courses in the technology sequence.
