“…Russian regulatory documents norms displacements only from vertical loads. Almost all multi-storey buildings in US are built of metal frames, however, despite such structure's widespread prevalence, the displacement issues from horizontal loads are only superficially explored [1][2][3]. The horizontal ones are perceived by the overlapping discs.…”

Calculations of horizontal loads such as wind are required even for low-rise buildings. With stores number increasing their influence increases. The horizontal loads are perceived by the flooring discs. Steelreinforced concrete floors with profiled decking are most often used in steel frame buildings. Floor slabs and frame’s joint work is ensured by shear studs. The article discusses a shear studs’ stress determining method from horizontal load. There are different slab supporting variants: slap supported on two sides and along slab's perimeter. The goal was to determine shear stress in each flexible stop. The tasks were solved by calculating and by computing. Then the results were compared. Therefore, the resulting formula allows determining shear stresses not only in square slab but in rectangular ones too. Shear stress knowledge in the studs allows to determinate frames’ displacements by horizontal loads. Frame displaces relative to the floor slab due to studs shear and flexibility. The derived displacements determining formula takes into account shear deformations and anchor compliance in different directions. Herewithin the article, proposed displacements formula is not checked, but only the components determining a method is proposed.

a b s t r a c tThe paper examines the effects of five major socialization agents-namely parents, peers, traditional media, the Internet, and music industry-on emerging adults' attitudes and behavior toward music piracy in the form of unauthorized downloading. Based upon self-reported behavior, our study shows that these socialization agents exert differential effects on music piracy. Specifically, peers and the Internet exert direct impact on both attitudes and behavior. Parents and music industry, however, only have indirect impact on emerging adults' piracy behavior through shaping their attitudes. The research further shows that the effects of socialization agents differ across consumer segments. A factor mixture modeling technique is first applied to disentangle the behavioral heterogeneity, and more observable factors such as demographic, social, and psychological variables are then utilized to profile members in each segment. From a managerial perspective, this research provides new avenues for managers and policy makers to design targeted prevention programs to curtail music piracy.Published by Elsevier B.V.Decision Support Systems 69 (2015) 70-81 ⁎ Corresponding author.

Introduction. Steel-reinforced concrete floors with profiled decking are most often used in steel frame buildings. The joint work of the floor slab and tertiary beam is ensured by shear studs. The article discusses a shear studs stress determining method from horizontal load. Studs are placed along the slab’s perimeter. The method based on the bolts’ group calculation analogy. Materials and methods. Based on the bolts group calculation design expressions were derived to determine the force in shear studs. To determine the obtained values reliability a finite element calculation was performed using the Lira-CAD software package. Different aspect ratios slabs samples were considered. The solution’s convergence was determined by various methods for a plate with 0.6 × 0.6 m dimensions with a small number of studs, after which the proposed solution convergence was studied for real dimensions of plates with a large number of flexible stops. Results. The resulting formula allows determining the stress in each flexible stop, in particular in the most loaded corner studs. The computer calculation was performed for the proposed method clarity and using possibility. The method’s use restriction was determined. In addition, the shear studs’ geometric characteristic’s definition explanations are given. Conclusions. The proposed calculation method allows to determinate any structural section’s shear stud’s stress. Therefore, it allows to choose stud’s optimal cross-section area or check its bearing capacity in the existing buildings and structures floors. Moreover, the stress value allows to determine the stud’s and a whole slab’s deformations.
