Abstract:
Researches on fluid-solid interaction effect of wind-induced vibration response and membrane structure were discussed. The two methodologies for solving this problem were introduced firstly. The first was a simplified aeroelastic model method. In this method, these additional aerodynamic feedback terms were described as added mass and aerodynamic damping, which could be studied by potential flow theory or wind tunnel test. The second was computational fluid dynamics simulation method. In this method, the computational fluid dynamics codes and computational structural dynamics codes were integrated into one program. Using this program, the process of wind-structure interaction can be simulated in time domain. Based on these two methods, corresponding works were done by means of theoretical derivation, wind tunnel test and numerical simulation. According to these works, some preliminary understandings of the mechanism of wind and membrane structures interaction were gotten. Finally, a simplified numerical simulation method was proposed. It is proved that this method is easier to handle than those above mentioned methods. It can be concluded that the couple effects are favourable for wind-induced vibration response under most conditions, which mean the results from wind-structure interaction analysis are about 30% smaller than those analysis methods without consideration of the couple effects. Meanwhile, it can not be excluded that there maybe exist some special cases that membrane structures can be destroyed by aeroelastic instability.
