The deformation monitoring of integrated truss structures (ITSs) is essential for ensuring the reliable performance mounted equipment in complex space environments. Reconstruction methods based on local strain information have been proven effective, yet identification faces significant challenges due to variable thermal–mechanical loads, interactions among structural components, and special boundary conditions. This paper proposes a reconstruction strategy tailored ITSs under combined load scenarios wherein deformations both primary attached panel systems are investigated. proposed approach utilizes Ko displacement theory as core algorithm, while least squares optimization method employed determine integration with unknown initial values during process. Validation conducted through diverse scenarios, results evaluated using errors root mean square. result demonstrates that can reconstruct mechanical thermal loads. Furthermore, optimization-based achieves accurate reconstructed case panels two-point fixed study provides an effective in-orbit reconstruction, addressing posed by loads configurations.
