Abstract:
The nonlinear dynamic time history analysis method was an effective approach to solve the wind-induced response for cable-membrane structures. If the scale of the problem was large, the number of times of the nonlinear dynamic time history analysis would be confined, and the statistics of structural response obtained for parametric analysis were too limited. As a result, the statistics for some parametric combinations were difficult to be predicted. To solve this problem, neural network was used. The idea was that the relation between the parameters and structural responses could be established after training with the samples. The results show that the proposed neural network aided parametric analysis method is efficient and accurate. Therefore, the proposed method is an effective access to sufficient data. The rules of variation of response statistics and dynamic coefficients with mean wind velocity and with the structural prestresses are obtained, which provide a scientific basis for calculations of design wind loads and extreme response of structural members.
