LOAD-SPAN : Dynamic Load Redistribution Analysis and Long-Span Structural Stability Assessment with AI-Assisted Analytical Support

LOAD-SPAN is an open-source structural reliability and long-span infrastructure safety framework for continuous dynamic load redistribution analysis, fatigue accumulation assessment, buckling stability evaluation, and AI-assisted monitoring support under strict physics-based constraints. The framework integrates four coupled analytical modules: Dynamic Load Redistribution Module (DLRM) Long-Span Structural Stability Assessment Module (LSSAM) Fatigue Accumulation and Reliability Module (FARM) AI-Assisted Support Layer (AISL) LOAD-SPAN combines direct stiffness analysis, Euler–Riks buckling assessment, Palmgren–Miner fatigue accumulation, Cornell–Hasofer–Lind reliability methods, progressive collapse evaluation, and physics-constrained AI-assisted forecasting into a unified continuous monitoring architecture for long-span systems including cable-stayed bridges, suspension bridges, offshore platforms, viaducts, and large-span truss structures. The framework provides: Continuous structural integrity assessment Real-time load redistribution tracking Reliability index monitoring Fatigue damage accumulation analysis Progressive collapse assessment AI-assisted anomaly detection and forecasting Long-Span Structural Integrity Index (LSII) governance logic LOAD-SPAN is distributed as open-source software under the MIT License and archived with DOI: 10.5281/zenodo.20422430 OSF Preregistration: 10.17605/OSF.IO/H35FU
