In the context of performance-based approaches for the design or assessment of concrete structures, time is the decisive variable and the durability issues are pronounced. Also, the reliability aspects are important as they is attribute to service life, maintenance, inspection, repair and the lifecycle cost – see also ISO 13823 (2008) and the fib Model Code (2010). Evidently, durability and rel...

Structural health monitoring has been one of particular concerns of the engineering community. Effective monitoring, reliable data analysis, rational data interpretation and correct decision making are challenging problems for engineers who specialized in structural health assessment field. Concrete structures were constructed for various purposes in a certain design life in the context of 'mai...

Over the last two decades fiber-reinforced polymer (FRP) rods have emerged as one of the most promising and affordable solutions to the corrosion problems of steel reinforcement in structural concrete. The application of FRP rods in new or damaged structures requires the development of design equations that must take into account the mechanical properties and the durability properties of FRP pr...

Aging of concrete structures occurs with the passage of time and has the potential, if its effects are not controlled, to increase the risk to public health and safety. Activities have been conducted to address factors related to quantifying the effects of age-related degradation on nuclear power plant concrete structures and components. Environmental effects that can lead to age-related degrad...

Structural health monitoring needs to produce actionable information regarding structural integrity that supports operational and maintenance decision making that is individualized for a given structure and its performance objectives. An effective Prognostics and Health Management (PHM) framework for aging structures (subjected to physical, chemical, environmental, and mechanical degradation) n...

Abstract—Drying is a phenomenon that accompanies the hardening of hydraulic materials. This study is concerned the modelling of drying shrinkage of the hydraulic materials and the prediction of the rate of spontaneous deformations of hydraulic materials during hardening. The model developed takes consideration of the main factors affecting drying shrinkage. There was agreement between drying sh...

Ab stract: The materials used in the manufacture of machine tools structures affects the metal removal rate; accuracy and surface finish of the products. The materials, in turn, have influence over the method of production, lead times and overall costs of the machine tool structures. Over a period of time machine tool builders relied on conventional materials, for the fabrication of machine too...
