Development Study on Large Span Aluminum Alloy Dome Structure

The dome structure has unique advantage among the large span structures. With the favourable mechanics characteristics and corrosion resistance of aluminum alloy, it will produce perfect effect to apply the metal to dome structure. The structural characteristics of the dome structure are studied at first; and the design methods for aluminum alloy dome structure are discussed also, including the selection and check of section, the design of gusset plate and support, etc. The CAD software ADD is coded to be convenient for design and research. Finally, the study is verified by a typical structure model test. [
