Structural damage identification in laminated structures using FRF data

A damage identification technique based on frequency response functions (FRF) sensitivities is presented. This technique leads to a set of linear equations, which is solved using an algorithm that constrains the solution to be physically admissible. Damage simulation and identification on a laminated rectangular plate is performed. The influence of the number of natural frequencies and mode sha...

a study on insurer solvency by panel data model: the case of iranian insurance market

the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.

Damage detection of skeletal structures using particle swarm optimizer with passive congregation (PSOPC) algorithm via incomplete modal data

This paper uses a PSOPC model based non-destructive damage identification procedure using frequency and modal data. The objective function formulation for the minimization problem is based on the frequency changes. The method is demonstrated by using a cantilever beam, four-bay plane truss and two-bay two-story plane frame with different scenarios. In this study, the modal data are provided nume...
