composite concrete-steel plate shear walls are the most critical resisting structural members that resist lateral and axial loads. This type of wall consisting of two steel faceplates presenting the outer skin, infill concrete and shear connectors which are used to provide the composite action of the steel faceplates with infill concrete in order to increase the strength and to reduce the local...

According to recent researches, angle shear connectors are appropriate to transfer longitudinal shear forces across the steel-concrete interface. Angle steel profile has been used in different positions as L-shaped or C-shaped shear connectors. The application of angle shear connectors in tilted positions is of interest in this study. This study investigates the behaviour of tilted-shaped angle...

In this paper, a new formulation along with numerical solution for the problem of finding a point-to-point trajectory with maximum load carrying capacities for flexible manipulators is proposed. For rigid manipulators, the major limiting factor in determining the Dynamic Load Carrying Capacity (DLCC) is the joint actuator capacity. The flexibility exhibited by light weight robots or by robots o...

Much of the accrued knowledge on physiology, pathology, degeneration, treatment and regeneration of peripheral nerves have resulted from experimental studies on small animals1-5, particularly on rats, whose spontaneous regeneration speed favors short-term studies. The sciatic nerve of rats is a reliable model for studying different kinds of injuries and treatment methods, with crushing injuries...

This paper presents an experimental and analytical study of the bond behaviour basalt fibre reinforced polymer (BFRP) bars in geopolymer concrete (GPC). Pull-out tests were conducted on ribbed BFRP embedded GPC cubes considering different bar diameters (6, 8 10 mm) embedment lengths (5db, 10db 15db) to investigate their effects terms bond-slip response, strength failure mechanisms. Results indi...

Assessing the behavior of composite structures which are subjected to impact loads is one of the important subjects in the field of mechanical sciences. Using thin-walled tubes which collapsed and absorbed the impact energy is a well-known method to prevent damages to the other parts of the structures. In this paper, deformations, crushing length, peak load, mean force and energy absorption cap...

Push-out-shear tests were used in this study to analyze lag screw connections timber-concrete composite (TCC) slabs based on the embedment depth. The goal of research is look into relationship between shear capacity and depth TCC, as well investigate strength wood. Experiments carried out at different depths (5.08 cm, 7.0 8.9 cm). prepared samples examined order determine failure modes provide ...

The geographic mosaic theory of coevolution predicts 1) spatial variation in predatory structures as well as prey defensive traits, and 2) trait matching in some areas and trait mismatching in others mediated by gene flow. We examined gene flow and documented spatial variation in crushing resistance in the freshwater snails Mexipyrgus churinceanus, Mexithauma quadripaludium, Nymphophilus minckl...
