Structural dynamics response prediction method and system based on encoder-decoder

The invention discloses a structure dynamics response prediction method and system based on an encoder-decoder, relates to the technical field of model prediction, and solves the technical problem that heterogeneous data of a time sequence external load and a non-time sequence structure parameter cannot be fused. The structural dynamics response prediction method comprises the following steps: acquiring a plurality of groups of input samples, calculating based on a finite element model to obtain an output sample corresponding to each group of input samples, and generating a sample training set; constructing an initial coding-decoding model, and training by using the sample training set to obtain a trained coding-decoding model; when structural dynamic response prediction is carried out on a to-be-measured dynamic structure, to-be-measured structural parameters and to-be-measured external loads of the to-be-measured dynamic structure are obtained and subjected to standardization processing, the to-be-measured
