Reinforced concrete used for bridge decks and pillars, highways and other transportation facilities experience loss of integrity over time caused by poor initial quality, action of de-icing salts, temperature changes, fatigue and, above all, delamination caused by corrosion of reinforcement bars (rebars for brevity). Electrical resistivity is sensitive to those losses of integrity. Using 3D num...

The research program consists of a series of investigations in the field and in the laboratory. First, four short-span bridges are installed so as to outline the construction-related issues associated with the use of these materials. The bridges are located in a residential area of St. James, Missouri and each bridge utilizes FRP materials in a slightly different way, demonstrating the versatil...

Link slabs designed for macroscopically crack free concrete bridge decks system were experimentally tested. The property requirements of the link slab material were considered. Special focus was placed on the fatigue and durability performance. Introduction of a ductile Engineered Cementitious Composite (ECC) material is proposed for its ability to control crack width and to exhibit high ductil...

during the past two decades, the use of bioplastics as an alternative to regular plastics has received much attention in many different industries. the mechanical and degradable properties of bioplastic are important for their utilization. in this research cellulose of wheat straw and glycerol were mixed by different weight ratios and then reinforced by using date palm fibers. to prepare the bi...

There is a growing interest in automatically building opinion lexicon from sources such as product reviews. Most of these methods depend on abundant external resources such as WordNet, which limits the applicability of these methods. Unsupervised or semi-supervised learning provides an optional solution to multilingual opinion lexicon extraction. However, the datasets are imbalanced in differen...

This paper presents the first part of a series of uniaxial cyclic tests on lap-splices. The work is conducted within the framework of a project on the seismic behaviour of existing, poorly detailed bridge piers which are typically constructed with a lap-splice above the footing. The test series presented here was initiated to study the influence of load history, especially with regards to the c...
