With advances in sensor technology and availability of low cost integrated circuits, a wireless monitoring sensor network has been considered to be the new generation technology for structural health monitoring. Wireless Intelligent Sensor and Actuator Network (WISAN) has hence been developed as a vibration based structural monitoring network that allows extraction of mode shapes from output-on...

Corrosion is a major deterioration mechanism of carbon steel bridges. Multiple maintenance actions have been proposed to meet the safety requirements for bridges subjected corrosion, including preventive maintenance, such as repainting, and essential girder replacement. Recently, corrosion-resistant has adopted bridge construction. However, comprehensive comparison different strategies still an...

The presented research deals with the optimal design of main girder an asymmetric box cross-section double-beam bridge crane. Moth-Flame Optimization algorithm (MFO) is used for solving this multicriteria optimization problem. This a relatively new population-based metaheuristic method. paper takes following criteria as constraint functions: strength, local stability plates (webs and top flange...

In this paper, adaptive neuro-fuzzy inference system (ANFIS) and artificial neural networks (ANNs) techniques are developed and applied to identify damage in a model steel girder bridge using dynamic parameters. The required data in the form of natural frequencies are obtained from experimental modal analysis. A comparative study is made using the ANNs and ANFIS techniques and results showed th...
