Modal identification of Bridge 44 of the Carajás Railroad and numerical modeling using the finite element method

Revista IBRACON de Estruturas e Materiais
Regular use and the effects of time can affect the behavior of a structure. Over time, problems such as the occurrence of small fissures, oxidation of steel elements, and excessive displacements at some points may arise in a structure.

Revisiting damping identification: limitations and comparative evaluation under impulse, white noise, and seismic excitations

Frontiers in Built Environment
Eigensystem Realization Algorithm (ERA), Stochastic Subspace Identification (SSI), Continuous Wavelet Transform (CWT), and Enhanced Frequency Domain Decomposition (EFDD) are four widely used damping identification methods.

Long-Term Structural Health Monitoring of Kashima Lighthouse

Buildings
The Kashima Lighthouse, one of the lighthouses that suffered damage in the 2011 Great East Japan Earthquake, required a careful investigation to estimate its long-term behavior and seismic vulnerability.

MODAL ANALYSIS AND VERIFICATION PERFORMED TO CYCLIC SYMMETRIC STRUCTURES BASED ON STOCHASTIC SUBSPACE IDENTIFICATION

Jixie qiangdu, 2016
To determine whether stochastic subspace identification（ SSI） based on the output-only measurements can identify the doublet modes of cyclic symmetric structures accurately,taking a brake disc as an example,modal analysis based on SSI and traditional ...

Application of Covariance Driven Stochastic Subspace Identification Method

, 2011
In this research the application of output-only system identification technique known as Stochastic Subspace Identification (SSI) algorithms in civil structures is carried out. With the aim of finding accurate modal parameters of the structure in off-line analysis, a stabilization diagram is constructed by plotting the identified poles of the system ...
