A Method for Remote Monitoring of Structural Health Based on the Nonlinear Phenomenon in Dynamic Response of Damaged Structures
نویسندگان
چکیده
A new method for remote crack monitoring, based on the breathing crack phenomenon and wavelet transform, is proposed. During vibration, edges of a crack come into and out of contact which causes non-linear effects in the response of a structure, due to changes in the structural stiffness, as the crack opens and closes. Wavelet Transform is applied to detect such nonlinear effects in the response signals of the structure. The results of numerical studies obtained from the FE analysis and experimental tests of simple specimens promise a practical technique for remote structural health

Structural 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...
متن کاملThe Effect of Axial Force Variations on Nonlinear Modeling and Seismic Response of Reinforced Concrete Structures
In order to increase the accuracy of evaluating seismic response of structures, it is critical to conduct dynamic analyses based upon precise nonlinear models being as consistent as possible with the real conditions of corresponding structures. The concentrated plasticity model including one elastic element and two nonlinear spring elements at both ends has been considered within the research c...
متن کاملEvaluation of the SEAOC/UBC97 Provisions for the Tall Base-Isolated Structures
The base isolation systems are among the passive control devices that have been used over the last three decades to limit the seismic-induced response of structures. In this regard, the Uniform Building Code provisions (UBC) has incorporated a special section for the seismic design of base isolated structures since its 1991 edition. Due to the importance of the behavior of these structures unde...
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...
