A New Approach in Numerical Modeling of ETFE Cushions Based on Interaction Theory

摘要：

　　ETFE cushion is made by filling air into ETFE films.An ETFE cushion maintains its shape and bears the external loading through the enclosed air.A new method of numerical modeling of ETFE cushions are proposed based on the interaction theory model of enclosed air and outer membrane.The interaction FE mod el of a regular hexagon ETFE cushion is established then, and the form-finding, filling air and loading analy sis are performed to verify the validity of FE model.It is shown that the numerical results agree with the test results well.
