A Structural Pounding Formulation Using Systematic Modal Truncation

Pounding Control of Structures Using Base Isolation

The most important property of a base-isolation system is to make the base more flexible than the elements of the superstructure, but it must still be stiff enough to resist typical pounding forces, wind loadings, and similar low-amplitude horizontal forces. However, the potential consequences of earthquake-induced poundings on seismically isolated buildings can be much more substantial, and, t...

Modal truncation for linear Hamiltonian systems : a physical energy approach

A Possible Modal Formulation of Comprehension Scheme

where q; is any property, is a very elegant principle. This principle, or better its substance, describes the naive set-universe. Unfortunately, in the most customary formalization, where any formula of the set-theoreticallanguage is accepted as a property, (CA) is inconsistent. As it is well-known the contradiction can be proved e.g. by following RUSSELL'S argument. Thus various approaches try...

STRUCTURAL DAMAGE PROGNOSIS BY EVALUATING MODAL DATA ORTHOGONALITY USING CHAOTIC IMPERIALIST COMPETITIVE ALGORITHM

Presenting structural damage detection problem as an inverse model-updating approach is one of the well-known methods which can reach to informative features of damages. This paper proposes a model-based method for fault prognosis in engineering structures. A new damage-sensitive cost function is suggested by employing the main concepts of the Modal Assurance Criterion (MAC) on the first severa...

The Identification of the Modal Parameters of Orbital Machines using Dynamic Structural Approach

The researcher measured the least number of frequency response functions required for the identification of modal parameters, in order to simplify the identification of modal properties of such systems. In this work, the orbital machines are supposed to be a combination of orbital and non-orbital components. Structural Approach specified the identification of dynamic properties only to those ph...
