Design optimization of space structures considering geometrical and material nonlinearities is achieved by continuous virtual sub population (CVSP) evolutionary algorithm. The design variables are cross-sectional areas of the elements. Design constraints include structural and stability constraints. Tension and compression stresses are limited to their critical values and nodal displacements are restricted to their allowable values. The overall loss of stability is also checked during the optimization process and some restrictions on design variable are considered. The test examples presented demonstrate that further reduction is possible in the structural weight by including the nonlinear behavior in the optimal design process.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
