This paper presents the experimental results of four full-scale coupling beams in which only horizontal reinforcements are placed, without diagonal reinforcements, with the aim to develop reinforcement details for coupling beams used in connecting side walls in a wall-slab structural system. Each coupling beam specimen was designed according to the deep-beam design procedure that does not use d...

Bulk metallic glasses (BMGs) possess a unique set of mechanical properties that make them attractive structural materials: yield strength > 2 GPa, fracture toughness ~20 MPa.m and elastic strain limit ~2%. BMGs can also be cast into intricate shapes which retain their dimensional integrity and require no further machining. Unfortunately, monolithic BMGs fail catastrophically under unconstrained...

Mechanically stabilized earth walls, MSEW, around Florida were instrumented through their concrete covers to survey corrosion rates of galvanized strip soil reinforcement by polarization measurements. The first broad survey was made 10 years ago as a baseline and a new survey is currently underway to assess long term corrosion rate trends. Initial results of an ongoing survey confirm low rates ...

Piled foundations are commonly employed to reduce settlements in artificial earth embankments founded on soft soil strata. To limit the number of piles and, consequently, construction costs, popular is use geosynthetic reinforcements laid at embankment base. Nowadays, complex interaction between geosynthetics, and not yet fully understood scientific literature, simplified displacement-based app...

In the present study, room temperature mechanical properties of pure magnesium, Mg/ZrO₂ and Mg/(ZrO₂ + Cu) composites with various compositions are investigated. Results revealed that the use of hybrid (ZrO₂ + Cu) reinforcements in Mg led to enhanced mechanical properties when compared to that of single reinforcement (ZrO₂). Marginal reduction in mechanical properties of Mg/ZrO₂ composites were...

Composite materials, especially polymer matrix composites, have been intensively studied for energy absorption applications. When the temperature is close to or higher than the glass transition temperature (Tg), the polymer matrix is usually viscoelastic. With an external loading, either dynamic or quasi-static, the relaxation of the network polymer chains would cause a considerable energy diss...
