Damage localization in shear buildings by direct updating of physical properties
The objective of this article is to present a new method for identifying the damage location in a multi-story shear building by direct model updating method. In this regard, structural perturbation matrices should be determined that are directly...
An iterative method for damage identification of skeletal structures utilizing biconjugate gradient method and reduction of search space
This paper is devoted to proposing a new approach for damage detection of structures. In this technique, the biconjugate method -BCG- is employed. To remedy the noise effects, a new preconditioning algorithm is applied. ...
A new method for damage detection of fluid-structure systems based on model updating strategy and incomplete modal data
In this paper, a new damage identification formulation is presented for damage identification of the specified fluid-structure system considering rigorous fluid-structure interaction and model updating method. The formulation is clearly proposed...
FINITE ELEMENT MODEL UPDATING OF A PRESTRESSED CONCRETE BEAM USING THE OPENSEES.NET SOFTWARE
, etc. To create a reliable and accurate finite element model of structures, one can use the model updating algorithms which are popular nowadays particularly. Model updating procedure is normally based on an optimization framework in with the model...
A new iterative model updating technique based on least squares minimal residual method using incomplete modal data
with the real structures due to significant discrepancies between test measurements and model predictions. This study is intended to propose an iterative model updating method to adjust the mass and stiffness matrices of the FE models by improving model updating...
The stability analysis for a class of time-delay networked control systems
Structural damage detection by a new iterative regularization method and an improved sensitivity function
A new sensitivity-based damage detection method is proposed to identify and estimate
the location and severity of structural damage using incomplete noisy modal data. For
these purposes, an improved sensitivity ...
