Hollow Triangular Cross-Section Calculating Precast-Monolithic Beams Methods with Account for Concrete Nonlinear Properties
Authors: Azizov Taliat , Kochkarev Dmitriy , Galinska Tatyana , Jurkowska Nadzieja
Published: July 2024

The article examines precast-monolithic reinforced concrete beams with a cross section in the form of a hollow triangle. The advantages of such beams are presented and say that their stiffness in torsion is ten times bigger than the similar rigidity of a T-beam with the same stiffness and bending resistance. The article introduces the method of manufacturing such beams without the use of form work which was developed by the author of the article. Earlier the authors investigated the stiffness of such beams in torsion and it is mentioned in the article. However, stiffness and bending resistance are not investigated. Resistance and stiffness of precast-monolithic beams under bending differs from the resistance and stiffness of the monolithic ones. Consequently, taking into account the nonlinear properties of materials the calculation of such beams is different. The method for calculating beams under bending is introduced and it is based on the application of the flat section hypothesis. This method is used in conventional methods of calculation. The difference from the traditional calculation is the addition of equilibrium stress to the equations which are perceived by sections of monolithic concrete with physical and mechanical characteristics that differ from those of the main part of the structure. In calculation the cross-section of the beam is reduced to the equivalent T-section. The obliquity of the side faces is taken into account and the thickness of the edge of the equivalent T-beam is understood as the doubled thickness of the side edge divided by the sine of the angle of obliquity of the edges. In order to apply this calculation method, at first, it is necessary to check the sufficiency of the presence of a transverse reinforcement in the grid which is laid in the construction of the structure. With a sufficient diameter and rod spacing of transverse reinforcement which are calculated according to the authorsâ€™ previously developed method, the structure can be calculated as monolithic with sections with different material characteristics according to the method introduced in the article. The calculations based on the above procedure showed a good match with the results of experimental studies of the authors.Â Â

The Issue of Determination of the Rigidity Characteristics of Reinforced Concrete Elements with Normal Cracks
Authors: Ðzizov Taliat , Sribnyak Nataliia , Tsyganenko Liudmyla , Yurin Oleg
Published: July 2024

Most of the reinforced concrete slab structures are statically indeterminate systems. In these systems, the redistribution of internal forces depends on the nature redistribution of rigidities between their separate elements. The presence of cracks significantly affects the change of elements rigidity of reinforced concrete structures. In the plate-ribbed systems, which include bridge structures, ribbed prefabricated and monolithic slabs, at the moment when normal cracks are wide enough, spatial torsion cracks may be absent. In this article the method of Â analysis of the rigidity of reinforced concrete elements with normal cracks is presented. The method is based on approximate striping of cross section to separate lines. The method is approximate, but it is rather convenient, since it can be used as a subprogram for analysis of complex statically indeterminate reinforced concrete systems. The torsional rigidity of every rod of the system is determined in such a subprogram atÂ  iterative analysis inÂ  automatic mode. As a result of this analysis, the forces in the rods of statically indeterminate system s are determined more accurately as the change of flexural as well as torsional rigidities caused by normal cracks formation were taken into account. The comparison of the results obtained by the torsional rigidity determination method with the results obtained by the numerical method confirmed theÂ  developed methodologyÂ Â

Published: July 2024

The purpose of the study is to formulate an approach to business administration based on the definition of the appropriate stage of enterprise life cycle. The proposed approach complements the existing methods by combining both the evaluation Â based on the analysis of characteristics of the internal components of the enterprise and the evaluation of the level of competitiveness of the enterprise and the level of financial and economic activity. The analysis of literature in the field of the theory of the enterprise life cycleÂ  has allowed to form a generalized five-stage model of ELC, which includes the stages of formation, development, maturity, diversification and decline. It has been substantiated that the machine-building enterprises in Ukraine, depending on the internal contextual variables, came to such stages of the life cycle as development, maturity, and diversification. At the first stage of development, the company has a simple structure, small size and low level of formalization. At the second stage, companies are barely older and bigger, use more complex types of organizational structures and more formalized. At the third stage, enterprises are even larger and older, have a higher level of formalization and a complex structure, which periodically varies. Indicators determining the level of financial and economic activity and competitiveness of the enterprise considerably increase the accuracy of the definition of the stage of the enterprise life cycle. According to the indicators, it is possible to draw a conclusion about the degree of efficiency of the enterprise at different stages of the life cycle. Therefore, in order to choose the appropriate direction of activity, strategy for the development of an industrial enterprise, or the method of decision-making, it is necessary to monitor various financial and economic indicators and indicators of competitiveness that will determine the stage of the enterprise life cycle.Â Â Â

Analytically, rational parameters of a vibration machine for internal compaction of concrete mixes are determined and rational modes of vibration exposure by a flat working body on a concrete mix are established.The dynamic system â€œvibration machine - concrete mediumâ€ is investigated, in which the latter is represented as a system with distributed parameters, taking into account the elastic, viscous, inertial and energy properties of the concrete to be compacted. The partial differential equation was compiled describing the change in stresses in a compacted medium depending on the dynamic elastic modulus, dynamic viscosity coefficient, inelastic resistance coefficient and inertia of the medium to be densified as a function of density, relative deformation and texture of the concrete mix. The propagation of visco-elastic-plastic deformation waves in a compacted concrete mix, represented as a half-space, is investigated. As a result of solving the wave equation of oscillations, the regularity of the propagation of viscous-elastic-plastic deformation waves in the half-space of a concrete mixture being compacted is established. The amplitudes of vibrations and stresses arising in the compacted mixture are determined depending on its physico mechanical characteristics. The vibration amplitude of the vibration machine was determined, its rational parameters were established, and rational modes of vibration impact on the compacted concrete mix found in the form of a half-space were found. A vibration machine in the form of a flat vertical plate, in the upper part of which a horizontal vibration exciter is mounted, is proposed. The given dependences allow one to substantiate rational ones depending on the physico mechanical characteristics of the medium being compacted, the thickness and width of the layer being compacted, the angular frequency of the forced oscillations and the amplitude of the disturbing force.Â Â Â

Authors: Vorontsov Oleg , Tulupova Larissa , Vorontsova Iryna
Published: July 2024

The current state of designing curvilinear objects of architecture and construction needs to take into account as many data and requirements as possible to ensure an appropriate model accuracy. In geometric modeling initial data, as a rule, are geometric characteristics and conditions, which are represented in numerical form (coordinates or values of parameters) with quite big arrays. In these conditions, methods of global continuous modeling with a single solution become ineffective. Because of this they require a usage of rather complicated mathematical algorithms and can not provide a necessary adequacy of models. Methods of discrete geometric modeling are free from these drawbacks.The purpose of this article is expanding possibilities of the classical finite difference method and the static-geometric method by applying a geometric apparatus of superposition. In discrete modeling of geometric images this allows using hyperbolic functions as interpolators.The result of this study is a computational template for continuous two-dimensional discrete interpolation. This allows to model geometric images of architectural and building constructions in the form of discrete frames of chain lines.Â Â Â

Published: July 2024

A retrospective analysis of the rural settlementsâ€™ typology has been carried out; the most common types of suburban rural settlements (SRS) have been identified: satellites, recreational and production ones. Within these basic types, 14 possible SRS subtypes are proposed. Modern tendencies in changes of SRS functional and planning organization are revealed. These changes relate to the deterioration of the cultural and domestic service sector, a significant increase in the rural settlement area with a decrease in its population, stratification of rural population by employment, income, ownership ratio, etc. Functional-planning organization of SRS is conditioned by its specialization. Functional specialization of a settlement, or formation a certain new type based on the traditional settlement, depends on the settlementâ€™s resources. The analysis has defined the determinants of the development and formation of functional SRS type, and has revealed the parameters that determine the total effect of these factors. To determine the functional type of settlement as a strategy for its development, the methodology of the pointâ€™s assessment of the determining parameters characterizing the settlementâ€™s resources is proposed. The algorithm of definition of suburban rural settlementsâ€™ functional specialization is developed, which provides comparison of alternative variants of SRS functional specialization.Â Â

The aims of the research work described in this paper are to use computational fluid dynamics (CFD) to investigate the impact of the downdraught mass flow rate generated and the homogeneity of the speed and heat profiles downstream of the multi- nozzles array. This included a work to define the optimum number, and the most effective arrangement of spray nozzles in a multi-nozzle array. Two different basic arrangements of the nozzles were studied; one in which a constant radius of 0.75 m was kept for the nozzle pitch circle as nozzles were added, and another, in which a constant distance of 0.75 m was guarded between all nozzles.Â  A second simulation was set up using the configuration with constant spacing but with a single central nozzle embedded.Â  A final simulation was carried out to determine if further optimization of the nozzle configuration could be obtained by altering the constant nozzle spacing in the range 0.35 to 0.85 m.Â  Based on these simulations, it was determined that constant spacing provided greater cooling with fewer nozzles than the configurations with constant radius.Â  Furthermore, it was found that the arrangement with 11 nozzles, with a nozzle spacing of 0.65 meters, gave the optimum overall performance.Â Â
Analysis on NOX Formation of Biofuels

This paper proposes on analysis of NOX formation of biofuels by using Corn Oil Methyl Ester (COME) and Palm Oil Methyl Ester (POME). The main contribution of this work is to study and analyse NOX emission from biodiesel, which can improve biodiesel content and component in order to reduce NOX formation coming from Compression Ignition (CI) engine. This is achieved by using alkaline base catalyst transesterification process to convert from palm and corn oil, containing low Free Fatty Acid (FFA), to biodiesel or biofuel. Biodiesel ratio, which is 400 ml of cooking oil: 100 ml of methanol: 2.8 g of potassium hydroxide (KOH), is used in transesterification process. The ratio is used to reduce alcohol consumption and cost. Almost 97% of biodiesel are yielded by using this ratio with direct heating from hot magnetic stirrer. The Fourier Transform Infrared Spectroscopy (FTIR) results determine the biodiesels illustrate the exhibition of C=O and C-O, which is the functional groups of esters, whereas the conventional diesel fuel does not have any of the functional groups. In gas emission testing, the biodiesel blends are burned in ceramic beaker including B20, B60 and B100. NOX formation increases when the percentage for biodiesel blends are increase. In ThermaCAM P65 inspection, the testing shows that the temperature is directly proportional with the percentage of biodiesel blends. COME produced the highest amount of NOX than POME and PBDF; POME is the suitable alternative biodiesel fuel that can be used for Compression Ignition engine beside PBDF. The analysis is useful for researchers who intend to reduce NOX emission and improve air cleanliness by determining parameters and factors that can influence NOX formation.Â Â

This paper shares one of the available options in developing an embedded palm vein imaging prototype. The prototype was developed by the Raspberry Pi SBC to promote portability of the embedded system. With an integrated illumination circuit utilizing two near infrared (NIR) peak wavelengths of 850 nm and 870 nm, this paper explores the ability of the prototype to capture palm vein pattern information. The prototype program, and image analysis were executed by Python language environment and OpenCV module binding. The captured palm images were compared with palm image datasets from the Chinese Academy of Sciencesâ€™ Institute of Automation (CASIA) and the Hong Kong Polytechnic University (PolyU). The comparison was done in terms of observation of the image recorded and palm vein pattern revealed, and also through image assessment metrics. Results show that palm images captured by the prototype has the ability to record vein pattern information in the image with pixel-by-pixel similarity rate of 96.54% (median) for the extracted vein pattern, compared to the CASIA (median: 96.07%) and PolyU (median: 90.99%) datasets. As such, the developed prototype can be enhanced its usage not only for biometric acquisition, but also for medical purpose.Â Â
