Abstract Although the identification and analysis of structures with a localized nonlinearity, either weak or strong, is within reach, multiple nonlinearities coexisting at different locations still challenge, especially if these are strong. In such cases, identifying each nonlinearity separately requires tedious work may not be possible all in some cases. this paper, an approach for experiment...

The given paper is closely connected with the experimental and numerical modal analysis of glass composite plate damaged by cut. In relation to tested composite, was performed help special measuring device Pulse 12. mentioned supplied company Brüel&Kjearand measurements were carried out using undamaged sample which prepared from material hereinbefore. investigated analyzed plates made six l...

In recent years some multi-mode pushover procedures taking into account higher mode effects, have been proposed. The responses of considered modes are combined by the quadratic combination rules, while using the elastic modal combination rules in the inelastic phases is not valid. Here, an optimum weighted mode combination method for nonlinear static analysis is presented. Genetic algorithm is ...

Abstract. The aim of this work is to present a structural model updating procedure based on recent variant Particle Swarm Optimization, called Continuous Optimization. In order validate the proposed model, modal parameters real scale large electrical device have been identified by measuring dynamical response system subjected measured input. Numerical results confirm robustness and reliability ...
