Grading:
Isometric description:
Collaborative learning is an educational methodology where students work in small groups to construct knowledge; where knowledge is considered to be a consensus constructed through individual contribu-tions and group discussion. In order to ensure each team project is the result of equitable individual contributions each student will submit a concise and critical evaluation of their team members. This evaluation is to be submitted on the project due date. Team members that fail to make sufficient quan-titative and/or qualitative contributions will receive a reduced grade for the respective project.

Structural Integration: Exercises in Structural Framing [Pavilion + Tower]arc321 Structures III _ Fall 2009, arc322 Building Technology V _ Structures II _ Spring 2010-12
Structural design can be defined as the art and science of configuring material into self-supporting and load bear-ing systems employed to accommodate a specific programmatic use. In the context of architecture, the program includes the technical mediation of site, the definition of quantitative space for human occupation and the rendering of qualitative space for human experience.
Previous laboratory projects have provided students the opportunity to explore and study structural behavior in abstract realms; as self supporting sculptural systems and as elements and systems defined in terms of force, form, material and connection. This laboratory project addresses application. Students are provided a simple archi-tectural program which establishes constraints and quantitative requirements. Aspects of the program are flexible and subject to interpretation in order to provide students the opportunities typically afforded an architect during schematic design and design development. Students are required to conceive and develop a structural design for the program. The structural designs focus on framing, tributary areas, horizontal and vertical systems, and foun-dations. Students are required to utilize references and rules-of-thumb for the sizing and spacing of all members. The designs are developed and illustrated in a series of structural drawings and physical models. Students work in teams of four. This exercise is repeated two to three times; each with a different programmatic challenge and a different material palette [open-air pavilion in wood and observation tower in steel]. Following the completion of this series of laboratory projects each student is expected to have the ability to effectively design a simple and techni-cally accurate schematic structural design, given a simple architectural program.
Objectives: following the completion of this project students should have:- the ability to conceive and develop a comprehensive structural design for a small scale architectural program- the ability to schematically size and space structural members- the ability to illustrate a structural design in drawings and model- an informed understanding of tributary areas, structural framing and foundations - an informed understanding of the qualitative and quantitative relationships between structural and architectural design
Course Context: The 1-2-3 way exercise is administered concurrently with lectures on structural systems, structural space and strategies for structural integration. It is also administered concurrently with computational exercises related to tributary areas and force flow, and the calculation of loads, reactions, shear and moment in beams, and the sizing of wood beams, columns and connections.
