Damage identification of structures using experimental modal analysis and continuous wavelet transform
Abstract: Modal analysis is a powerful technique for understanding the behavior and performance of structures. Modal analysis can be conducted via artificial excitation, e.g. shaker or instrument hammer excitation. Input force and output responses are measured. That is normally referred to as experimental modal analysis (EMA). EMA consists of three steps: data acquisition, system identificatio...
متن کاملSCALING WITH KNOWN UNCERTAINTY: A Synthesis
Scale is a fundamental concept in ecology and all sciences (Levin 1992, Wu and Loucks 1995, Barenblatt 1996), which has received increasing attention in recent years. The previous chapters have demonstrated an immerse diversity of scaling issues present in different areas of ecology, covering species distribution, population dynamics, ecosystem processes, and environmental assessment. Scale iss...
متن کاملOptimal Sensors Location Using Modal Assurance Criterion in Modal Identification of Concrete Gravity Dams
Determination of the optimal sensors location in order to identify of modal parameters, especially in large structures such as dams, is one of the practical issues, which is widely used in damage detection and structural health monitoring. The main objective of this study is to obtain the most information from the dynamic response in a concrete gravity dam by minimizing the non-diagonal element...
متن کاملMixed Estimators of Ordered Scale Parameters of Two Gamma Distributions with Arbitrary Known Shape Parameters
When an ordering among parameters is known in advance,the problem of estimating the smallest or the largest parametersarises in various practical problems. Suppose independent randomsamples of size ni drawn from two gamma distributions withknown arbitrary shape parameter no_i > 0 and unknown scale parameter beta_i > 0, i = 1, 2. We consider the class of mixed estimators of 1 and 2 under the res...
