Considering the characteristics of wind-membrane interaction

a block reduced order model is proposed.The fluid-structure interaction is considered to be composed of force model and structural dynamic model.The force model aims at structural force exerted by fluid

including force amplitude and frequency

which can be fitted by inflow conditions.Considering nonlinearities of membrane structures

consider that frequency error correlates with modes

and POD is utilized to adjust the time coefficients of each mode to obtain the nonlinear corrector.The output of the force model inputs into the structural model to obtain the membrane responses.The block reduced order model is applied to a wind-membrane interaction analysis.Wind-induced responses

wind pressure coefficients

and efficiency are computed and compared with those from full-order model.The results show that the proposed reduced order model can accurately predict wind-induced responses and wind pressure coefficients and the computing efficiency is greatly improved.
