BASIS PURSUIT BASED GENETIC ALGORITHM FOR DAMAGE IDENTIFICATION
In damage detection the number of elements is generally more than the number of measured frequencies. Consequently, the corresponding damage detection equation is undetermined and thus has infinite solutions. Since in the damaged structures most of their elements remain healthy, the sparsest solution for the damage detection equation is mostly the actual damage. In the proposed method, the dama...
متن کاملGenetic Algorithm Based Damage Identification in Non-homogenious Structural Members
Non-homogeneous structural members such as beams are very important in various engineering applications and for experimental analysis purposes. A minor damage on any part of the structure reduces the strength of the structure and leads to a major failure. So, the identification of damage is very important and essential at an early stage. In this paper, a new formulation of an objective function...
متن کاملAn Algorithm of Association Rule Based on Cloud Computing
Large-scale data processing is one of the focal points of research in information technology. The traditional algorithm of association rule is in a large overhead, due to the frequent itemsets being computed on the dataset. The rapid development of distributed technology makes cloud computing a reality in the implementation of data processing algorithms. To improve the traditional association r...
متن کاملA NEW APPROACH BASED ON FINITE ELEMENT MODEL UPDATING FOR STRUCTURAL DAMAGE IDENTIFICATION
In this study, the finite element model updating was simulated by reducing the stiffness of the members. Due to lack of access to the experimental results, the data obtained from an analytical model were used in the proposed structural damage scenarios. The updating parameters for the studied structures were defined as a reduction coefficient applied to the stiffness of the members. Parameter v...
متن کاملStructural Damage Identification of Plate Structures based on Frequency Response Function and Natural Frequencies
In this paper, a structural damage identification method (SDIM) is developed for plate-like structures. This method is derived using dynamic equation of undamaged/damaged plate, in which local change in flexural rigidity is characterized utilizing a damage distribution function. The SDIM requires to modal data in the intact state and frequency response of damage state where most of vibration ba...
