Study on Damage Identification for a Simply Supported Reinforced Concrete Beam Based on the LMBP Neural Network

Design, Construction, Rehabilitation, and Maintenance of Bridges, 2011
The problems such as difficult to obtain the training sample, slow to convergence for learn algorithm is encountered in damage identification using BP neural network. To solve the above problem, finite element model updating technique and Levenberg-marquardt algorithm are adopted.

Study on Damage Identification of the Simply Supported Beam Employ the Difference of Deflection Influence Line under Symmetrically Load

Applied Mechanics and Materials, 2012
In order to solve the problem that it need too large number of sensors and data of undamaged structure, the method of damage detection employ difference of deflection influence line under symmetrically load is proposed. theoretical derivation and finite element simulation shows that the curvature of the influence line is less than zero when the moving ...

Experimental and numerical studies on damage localization of simply supported beams based on curvature difference probability method of waveform fractal dimension

Journal of Intelligent Material Systems and Structures, 2012
Accurate structural damage localization in engineering is still a challenge due to high noise and low accuracy of the structural finite element model. With the most basic type of construction, the simply supported beam is the most widely used type of structures in short and medium span bridges.

Application of residuals from regression of experimental mode shapes to locate multiple crack damage in a simply supported reinforced concrete beam

Measurement, 2012
Abstract The objective of the study was to propose an effective, simple and reliable technique to determine the location of triple-crack damage in a simply-supported reinforced concrete beam using the method of mode shape regression. The study required simply supported finite element reinforced concrete beam models to be constructed with one as ...
