“…Analyzed high-rise apartment complex Planned building is a unique structure with a fairly complex space-planning and design solutions that do not have direct counterparts. In domestic and foreign regulations and references [3] do not provide data of the distribution of wind loads on structures enclosing structures of similar shape. The planned complex is located in glacial hills.…”

“…Wind is one of the negative factors that require attention at the design stage of buildings. Construction of high-rise buildings substantially alters the conditions of circulation of the surface layer of air [3,4,5]. According to SNIP 2.01.07-85 * "Loads and effects" wind loading increases with height above the ground.…”

Currently, there is a strong need of high-performance and environment-friendly paving materials in Russian Federation. Sulfur dumps near the oil industry enterprises consumes area which otherwise could be occupied by vegetation, contributing to the improvement of the environmental situation. Incorporation of sulfur in bulk building materials contributes to decrease of load to the environment. The results of numerous studies of sulfur-extended asphalt concretes are summarized in the present work. For the suppression of hydrogen sulfide and sulfur dioxide we propose to use the complex nanoscale modifier. The application of such modifier leads to several positive effects. Both amount of sulfur in constructional mix and mobility of the mix can be increased. The values of operational properties, notably compressive strength and resistance to rutting, can also be increased. Due to consumption of industrial by-product, the environmental load decreases in regions near the oil and gas industry enterprises.

“…In this paper, to determine the reinforcement positions of the flat element along its thickness, we propose to construction picture of propagation of the fronts of elastic waves [1][2][3][4] and separately to find points where the reflected longitudinal and transverse waves meet [3,5]. In these points the largest compressive or tensile stresses will occur [6][7][8] and exactly in their vicinity it is proposed to place reinforcing elements in the form of fibers, filaments or rods.…”

In this investigation, we realize the idea to link reinforcement positions of plane constructions with points of origin of the largest kinematic and dynamic characteristics after impact on the target. It is assumed that the largest dynamic characteristics, e.g. stresses, arise in the intersection points of wave surfaces, which 3542 Alexey A. Loktev et al. have experienced multiple reflections from the boundaries of the target. The origin and propagation of wave surfaces with finite velocities in the proposed model of the deformation of a flat target become possible due to the use of hyperbolic equations of Uflyand-Mindlin-Reissner type describing dynamic displacements of the points of the plate with consideration of the transverse shear deformation and rotational inertia of cross-sections. In this paper, we propose an algorithm taking into account different rheological properties of the interacting bodies, which is based on the analytical method of representation of unknown quantities in the form of expansions in a spatial coordinate and time, initial and boundary conditions, compatibility conditions. The final integro-differential equations are solved using numerical computational schemes. Moreover, the creation of algorithms for calculating impact interactions with a given wave portrait in colliding bodies, as well as their implementation in a software application with a simple and intuitive interface are desirable. In this paper, we developed a computational algorithm and a software system and tested them on the example of a flat target composed of materials with various mechanical characteristics. Furthermore, we provide specific recommendations for locations of reinforcing filaments or rods in the composite material.
