| Abstract: | Aiming at strongly coupled partitioned method of fluid-structure interaction in wind-induced vibration of membrane structures,reduced order models are applied to the calculating process of the fluid-structure interaction.Reduced order models of fluid and structure are established firstly,and the procedures for performing strongly coupled partitioned method by reduced order models are established.To achieve strongly coupling of fluid and structure,Jacobians of fluid and structure are obtained by adopting red... |
