Comparative Evaluation of Vorticity Transport Modeled Distortions and High-Fidelity ANSYS Solutions Using Modal Assurance Criterion
… Bulk Swirl, Twin Swirl, and Quad Swirl. Modal decomposition through singular value decomposition (SVD) is performed on the resulting in-plane velocity profiles for both the ROM and high-fidelity RANS simulations. The accuracy of the ROM is assessed through both conventional error analyses …

An attempt to quantify errors in the experimental modal analysis process
Experimental modal analysis (EMA) techniques have become a popular method of studying the dynamic characteristics of structures. A survey of literature available reveals that experimental modal models resulting from EMA may suffer from inaccuracy due to a host of reasons. Every stage of EMA could …

Experimental Damage Diagnosis of a Model Three-Story Spatial Frame
… metal frame building was constructed. Using Star Modal software, dynamic structural properties were obtained from modal decomposition on experimental tap test responses. The natural frequencies and mode shapes of the structure established an as-built baseline for comparison to ten other scenarios …

Effects of structural repair and strengthening on stiffness and ultimate capacity of corrosion-damaged RC beams
… and dynamic properties (natural frequencies and modal shapes). The effect of patch repair and strengthening on corrosion damaged beams was deduced from the changes in their ultimate capacities. From the deflection measurements measured during the corrosion process, stiffness decreased with the …

Damage detection in reinforced concrete square slabs using modal analysis and artifical neural network
… based damage detection methods, particularly modal based methods, are found to be promising in evaluating the health condition of a structure in terms of detection, localisation, classification and quantification of the potential damage in the structure. Damage in composites and the …
