Mix proportioning of high-performance concrete by applying the GA and PSO
High performance concrete is designed to meets special requirements such as high strength, high flowability, and high durability in large scale concrete construction. To obtain such performance many trial mixes are required to find desired combination of materials and there is no conventional way to achieve proper mix proportioning. Genetic algorithm is a global optimization technique based ...
متن کاملDevelopment of Fragility and Reliability Curves and Seismic Vulnerability Evaluation of Talehzang Concrete Bridge
Bridges are potentially one of the most seismically vulnerable structures in the highway system during earthquake 
 
events. It is known that the seismic performance of transportation systems plays a key role in the post-earthquake emergency management. Hence, it is necessary to evaluate both physical and functional aspects of bridge structures. The physical aspects of the seismic perform...

متن کاملDelamination and concrete quality assessment of concrete bridge decks using a fully autonomous RABIT platform
One of the main causes of a limited use of nondestructive evaluation (NDE) technologies in bridge deck assessment is the speed of data collection and analysis. The paper describes development and implementation of the RABIT (Robotics Assisted Bridge Inspection Tool) for data collection using multiple NDE technologies. The system is designed to characterize three most common deterioration types ...
متن کاملLow Porosity, High Strength Concrete for Bridge Decks
IN TR O D U CTIO N -TH E PROBLEM A few years ago a problem that previously had been a modest highway maintenance concern suddenly became a major source of dif ficulty and expense to highway departments in many areas of the coun try; including Indiana. In brief, concrete bridge decks, some new, started to spall, then delaminate, then come apart in relatively large chunks. The problem was quick...
