Kurzfassung:
A physics-informed Rigid-Plate-Spring (RPS) method is established to learn compression-only spring laws for symmetric tunnel joints. The method is then developed to be able to consider asymmetric joint configurations and connectors. Taking full-scale joint tests and structural tests for validation, the developed method can accurately capture joint behavior both in joint level and structural level, enabling efficient design and O&M assessments.
