New Forms Of Cable Domes Development And Mechanical Calculation

Cable dome structure is developed in the idea of tensegrity structure; the idea is "continuous pull, discontinuous press". The idea was put forward by the famous American architect Fuller in the1940s. Cable Dome has experienced several years of development and trials, because of its great features of the shape and the force, it get a lot of people’s attention. Built in1996, the Georgia Dome is the one of the most famous dome, designed by American architect M. Levy.At present, the main forms of cable dome are Levy’s and Geiger’s, but the structure from of cable dome is variability, it’s from is not limited to union and ribbed, it’s facade can also have a lot of changes. This paper introduces four new forms Cable Dome. They are Three Direction Orthogonal Cable Dome, Irregular Site Cable Dome, Plane and Facade Changed Cable Dome, Center Opened Cable Dome. We will study those four forms Cable Dome and compare with the Levy’s Cable Dome.This paper is divided into several areas, the first is shape change, based on Levy’s, we design four forms Cable Dome, plane and facade changed, architectural style after lay the membrane. Then static calculation and analysis, analysis vibration characteristics, Spectrum analysis and Time history analysis.This paper presents four new forms of Cable Dome. So, the main purpose of this paper is to show that the form of Cable Dome is variability, focuses on the feasibility of these four forms Cable Dome. Using ANSYS finite element analysis tool for Cable Dome study and compare with the Levy’s Cable Dome. Summarizes the advantages and disadvantages of four forms Cable Dome, and serve the research of the Cable Dome in future.
