INTRODUCTION:
A tension structure or tensile structure is a structure that is characterized by a tensioning of the fabric or pliable material system to provide the critical structural support to the structure. Tension structure utilize technical fabric roof membranes, a combination of catenaries cables and clamping systems, and a minimal amount of framing to create proportionally lightweight structures capable of spanning great distances.
A.TYPE OF TENSILE STRUCTURE TO BE USED Cable structure which is a long-span structure that is subject to tension and uses suspension cables for support.
B.STRUCTURAL FUNDAMENTALS: The building envelope or building enclosure is the physical separator between the interior and the exterior environments of a building. It serves as the outer shell to help maintain the indoor environment together with the mechanical conditioning systems and facilitate its climate control. The functions of the building envelope are to support or resist and transfer mechanical loads, to control the flow of matter and energy of all types and to meet human desires on the inside and outside of the structure. The building structure is the structure itself which support the building envelop inside and outside the building.
C.FUNCTION:
The structural system of the structure are subject to pure tension under the action of external loads or tension structure and the function of the structure would be Metropolitan Domestic Airport terminal building which the tensile stress is uniformly distributed over the cross sectional area of members, the materials would be utilize in the most efficient manner.
D.CRITERIA:
a. SAFETY: The first and most important performance property of tensile structure is the tensile strength of the architectural fabric. Second, the Tear strength properties are related to a combination of factors involving the base fabric, weave/knit construction and adhesion values to obtain the
