DENVIR AIRPORT by Fentress Bradburn Architects
Introduction The massive, 1,200- by 240-foot facility features a striking “mountain range” canopy that utilizes Birdair’s innovative steel cable systems and durable PTFE Teflon-coated fabric membrane. Punctuating this “ridge and valley” structure is a 900-foot atrium, known as the Great Hall, which rises to a height of 126 feet and welcomes visitors with an abundance of translucent, natural light. This graceful, lightweight roof incorporates two layers of fabric membrane to ensure proper sound control and sufficient insulation against Denver’s demanding climate conditions. Architect : Fentress Bradburn Architects Building type : Airport Project scope : Airport Terminal Building Size : 189,000. sq ft. (17,558.sq.m.) Completed : 1995 Location : Denver, Colorado, United States.
FORCESS & LOAD DISTRIBUTION Tensile forces Compressive forces
Tensile Fabric Membrance Chemically inert, highly resistant to dirt and pollution, and provides a long lifecycle with minimal service.
Mast top
Mast
Edge cable with clamps
This is where the ridge cables, Arch-shaped valley and horizontal cables are attached to the masts.
The masts are anchored to the framing of the roof surfaces along the east and west sides of the terminal.
Used mainly for PTFE-coated fiberglass fabric, but also for PVC-coated poly ester fabric when edge spans are longer than 20m.
STRUCTURE ELEMENTS
Cable anchor structure
Arch-shaped valley cables
Ridge cables
This is where the ridge cables, valley and horizontal cables are attached to the masts.
It resist upward and outward loads (wind loads).
It resist downward forces (snow loads and dead loads) and are draped between the masts.
EXPERIMENTAL MODEL Conclusion: We learned how tensile structure functions and works by doing mock-up model. This was a good opportunity to test the tensile forces and find out what materials are more suitable to strengthen the structure and well presented aesthetically. Materials Used: 1. Foam board as a base. 2. White fabric material represents the tensile fabric structure as the roof. 3. Satey stick working as mast as a primary structure, it supports the tensile fabric structure. 4. Fishing string functioning as a cable for tieding down the roof structure.
