Solving Vibration Equations of MDOF Systems by Modified Differential Transform Method

Solving Vibration Equations of MDOF Systems by Modified Differential Transform Method

Vibration equations of discrete multi-degrees-of-freedom (MDOF)structural systems is system of differential equations. In linear systems,the differential equations are also linear. Various analytical andnumerical methods are available for solving the vibration equations instructural dynamics. In this paper modified differential transformmethod (MDTM) as a semi-analytical approach is generalized for thesystem of differential equations and is utilized for solving the vibrationequations of MDOF ...

Damage Detection of Concrete Beams using Nonlinear Features of Forced Vibration

Damage Detection of Concrete Beams using Nonlinear Features of Forced Vibration

A new indicator is proposed to facilitate the detection of newly induced damage in reinforced concrete(RC) beams, based on the transient characteristics of nonlinear vibration. Two full-scale RC beams,one reinforced with externally bonded fiber-reinforced-polymer sheets, are tested to develop theproposed damage indicator. Both beams are statically and dynamically loaded to correlate thedynamic characteristics of the beams to the damage level. A phenomenological model is developedto simulate the ...

Using Non-Linear Vibration Techniques to Detect Damage in Concrete Bridges

Using Non-Linear Vibration Techniques to Detect Damage in Concrete Bridges

vvThere has been much work published in recent years on the use of vibration characteristicsto detect damage in bridges. Almost all of this work has been based on theassumption that the vibration is linear, i.e. the natural frequencies are not dependent onthe amplitude of oscillation. The aim of the work presented here was to investigate thepossibility of using changes in the non-linear vibration characteristics to detect damagein reinforced concrete bridges.These changes in the non-linear ...
