Abstract

Aluminum alloy is widely used in civil engineering because of the advantages of light weight and high strength. But the elastic modulus of aluminum alloy is only one-third of steel, and the deformation of aluminum alloy is more notable. Second-order nonlinear finite element analysis is performed to analyze a multilayer aluminum alloy frame. Precise second-order nonlinear analysis is compared with the approximate second-order analysis method which is adopted by the Chinese structural aluminum alloy design code GB50429. The approximate second-order analysis method adopted by the code are found partial to be unsafe when material nonlinearity being considered. It is recommanded that the current frame design method be modified to provide a safe and reliable design for Aluminum alloy frame considering both geometric and material nonlinearities .
