The level of maximum punching strength is major importance to design highly stressed slab-column connections and choose the type shear reinforcement. Since a couple years, there consensus that shear-reinforced concrete slabs can be defined as multiple reference without upper bound this load-increasing effect depends mainly on anchorage arrangement reinforcement elements. Despite numerous resear...

In order to provide appropriate performance on potentially hazardous winter or icy road surfaces, it is common to employ specific tyres developed for such conditions. Such winter tyres may contain studs embedded in the tyre tread, or they may be studless. Additionally, it is possible to use so called all season tyres which are also fitted for winter conditions. In some northern countries, the u...

The behaviour of squat shape partially grouted concrete masonry shear walls with fixed-end boundary conditions subjected to constant average axial stress and cyclic lateral loading was investigated. Two replicas were tested each combination horizontal reinforcement ratio (0.12%, 0.06%, 0.03%) four end anchorage (straight, 90°, 180°, studs). the compared in terms strength, ductility, stiffness, ...

Rib shear connectors are gaining increasingly attention in the field of composite constructions. Especially bridge constructions, rib offer many advantages compared to conventional such as headed studs. In order describe load-bearing behaviour under cyclic loading, successively increasing slip resulting from loading must be taken into account. The latter leads growth relative displacements alon...

A 9-year-old boy presented to our department 8 days after attempting to insert a non-piercing magnetic ear stud on either side of his nose. He had been unable to remove them, and both magnetic parts of the ear studs were still present in his nose. Examination of the nose was difficult, as he was unco-operative and his nose was filled with mucus and crusts. X-rays of the nose revealed the two ea...

This paper aims to study the composite action on web-post buckling (WPB) resistance of cellular beams with precast hollow core slab (PCHCS) units and concrete topping (PCHCSCT). Geometrical material non-linear analyses are performed. A parametric is developed, varying opening diameter, width shear stud spacing, single double row. It was found that models row studs showed global greater than or ...

This paper presents theoretical modelling of the sound transmission loss through double-leaf lightweight partitions stiffened with periodically placed studs. First, by assuming that the effect of the studs can be replaced with elastic springs uniformly distributed between the sheathing panels, a simple smeared model is established. Second, periodic structure theory is used to develop a more acc...

The aim of this study was to determine the current state of genetic diversity and to assess the substructure and spatial structure at individual level based on analysis of microsatellite variations within Lipizzan horse population. The genomic DNA samples were obtained from totally 418 horses, originating from Slovenian (357) and Slovak (61) studs. A set of 13 microsatellite markers (AHT4, AHT5...

Slab – column connections that are subjected to combined gravity and horizontal loading during an earthquake prone premature failure due punching shear. Traditional solutions avoid increase the displacement capacity of this type connection include using stirrups double-headed studs as shear reinforcement. The use High-Performance Fiber Reinforced Concrete (HPFRC) in a small region slab around s...
