Several Issues in Designing Durable RC Structures

Designing durable icephobic surfaces.

Ice accretion has a negative impact on critical infrastructure, as well as a range of commercial and residential activities. Icephobic surfaces are defined by an ice adhesion strength τice < 100 kPa. However, the passive removal of ice requires much lower values of τice, such as on airplane wings or power lines (τice < 20 kPa). Such low τice values are scarcely reported, and robust coatings tha...

Issues Related to Durability of Frp Reinforcement for Rc Structures Exposed to Accelerated Ageing

Corrosion of steel reinforcement in an aggressive environment constitutes a serious problem for many reinforced concrete (RC) structures. Fiber-reinforced polymers (FRP) rebars represent a potential solution to this situation. Even if FRP reinforcement shows a good resistance to electro-chemical corrosion, long-term behavior must be investigated and proven. The mechanical properties of FRP rods...

Oscillation Test Structures of Active Rc Filters

Design-for-test modiications of diierent types of active RC lter stages for the oscillation-based testing are proposed. Additional switches or a feedback loop network are employed. The rst solution ooers the possibility of a simple built-in test implementation while the second is more applicable to the use of an external tester.

On coalition formation: durable coalition structures

We define a solution to the problem of coalition formation that applies to purely hedonic games. Coalition structures satisfying our requirements are called durable, and we interpret them as much more likely to last than those coalition structures not satisfying the requirements, which we call transient. Durability results from a combination of foresight and extreme risk aversion on the part of...
