BlueprintAgent: Constraint-Triggered Targeted Revisits for Simulation-Ready Generation from Scanned Structural Blueprints
Zhouyuan Xu, Chen Yang, Linhao Wang +2
Converting in-service reinforced-concrete (RC) building blueprints into simulation-ready models---structured frame representations that support deterministic FEM export and qualifi…
Beyond Arbitrary Geometry: Topology Generalization In neural PDE Operators
Peiyao Chen, Zhouyuan Xu, Ran Ding +3
Neural operators that accept arbitrary meshes are often treated as geometry-general, but unseen domain topology changes both the invariant and decaying subspaces of a PDE operator.…
Thinking in Structures: Evaluating Spatial Intelligence in Constraint-Governed Spaces
Chen Yang, Guanxin Lin, Youquan He +10
Spatial intelligence is crucial for vision--language models (VLMs), yet many scene-centric benchmarks evaluate unconstrained environments where a single image may admit multiple pl…
Formula-Guided Machine Learning for Ground Vibration Propagation and Attenuation Modeling
Pei-Yao Chen, Chen Wang, Fang Yan +4
Understanding the propagation and attenuation patterns of ground vibrations is critical for evaluating the impact of environmental disturbances on large-scale scientific facilities…
Data Fusion for Full-Range Response Reconstruction via Diffusion Models
Wingho Feng, Quanwang Li, Chen Wang +1
Accurately capturing the full-range response of structures is crucial in structural health monitoring (SHM) for ensuring safety and operational integrity. However, limited sensor d…
