Tensioned Fabric Structures
Summer II 2010
NAAB Objectives: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 18, 21, 23, 24, 25, 33.
Type of Course:
Lecture format 3 credit course Meets three times a week: Monday, Wednesday & Thursday
from 1:00 to 4:00 pm Location: Kupfrian 107.
Course Overview:
The course covers the structural technology, history and design considerations of cablesuspended, cable-stayed, tensioned fabric and air-supported structures, and the use of light-tensile
structures in architecture. The course also offers an overview of the engineering standards that
provide guidelines and recommendations for their design. A long list of well-known cable and
tensioned fabric structures will be used to illustrate the structural design concepts. The examples
focus mainly on buildings and roof structures. The tensioned fabric roof examples include some
of the impressive projects of Geiger Berger Associates and Horst Berger Partners who pioneered
the evolution of tensioned fabric structures in the US and elsewhere.
Learning Objectives:
The objectives of this course are to teach the students:
v
The engineering principles at work in cable and tensioned fabric structures.
v
The history of the relatively recent technologies of light-tensile structures.
v
The engineering standards regarding cable roofs and tensioned fabric structures.
v
Different famous case studies illustrating the engineering concepts outlined in this
course.
v
The criteria for the selection of a light-tensile structural system.
v
The different types of materials used.
Course Requirements:
Students are expected to take a mid-term and a final examination and to complete two
projects in relation to the design of cable roofs and tensioned fabric structures. Both exams are
closed book. Tentative test dates are given below. No make-up exams will be given without a
valid reason. Students are expected to submit assignments in a timely manner.
Grading Criteria:
Mid-term examination: 30% - Tentative Date: Wednesday, July 21 st, 2010.
Projects: 20% each Due dates will be announced.
Final examination: 30% - On the last day of Summer II, Monday, August 9, 2010.
