This invention achieves three-stage variable stiffness friction adaptive energy dissipation by providing constant friction force during the small displacement stage, exponentially increasing friction force during the medium displacement stage, and mechanically limiting and locking during the large displacement stage, which can better adapt to the differentiated requirements of structures for damping force and stiffness under earthquakes of different intensities.

This application relates to the field of artificial intelligence technology, and in particular to a knowledge graph question answering method, system, and storage medium based on structural induction and differentiable connectivity constraints. It decomposes natural language questions to obtain seed entities, employs personalized random walks around these seed entities to obtain their structural importance distribution, and integrates this distribution with semantic similarity as a retrieval criterion to filter candidate entity subgraphs. A gated graph neural network with geometric features such as hop count and node degree is introduced into the candidate subgraphs for structural inductive reasoning. Furthermore, differentiable connectivity constraints are constructed to softly model entity rewards and edge costs, ensuring the compact connectivity of the reasoning subgraph. End-to-end optimization is performed by combining question answering main loss, ranking loss, and connectivity regularization, thereby achieving accurate reasoning and prediction of answer entities in the knowledge graph.
