The Model of Failure for Exploited Brick Buildings in the Conditions of an Unevenly Deformed Base
Authors: Kichaeva Oxana
Published: July 2018

The article proposes a model of failure for exploited brick structures and buildings in the conditions of an unevenly deformed base as a function of time. This model includes the corresponding models of the structural element, loads and effects, the base model, the material model, the environmental impact model, and the phenomenological model of damage accumulation. The author has constructed the distribution function of the generalized force influence on brick buildings in the conditions of an unevenly deformed base. Based on the results of experimental studies, the mechanisms of destruction of brickwork in conditions of a single-axial stress state are formulated. A solution has also been proposed that makes it possible to determine the coefficients of the elastic base for a layered base with any number of layers with different deformation characteristics. The laws of the distribution of such brick parameters are obtained: compressive strength, flexural strength, length and height, also the possibility of applying the normal distribution law for the properties of the materials of the exploited structures is shown. In the damage accumulation model, it is suggested that the criterion for the technical state of a brick element is to take a set of numerical parameters of cracks in the material: the width of crack opening, the length and density of cracks. The aggregate of these numerical parameters is a quantitative integral characteristic of the degradation process. The connection of the above parameters with reliability makes it possible to assess the reliability of the element in the crack resistance, depending on the exploiting time. The reliability assessment of an element is formulated as a search for the probability of the non-exceeding of the limiting state by the controlled parameter, after which the probability of non-extinction by the generalized parameter is determined. The proposed model can serve to predict the resource of the «building-base» system at all stages of the life cycle.

Authors: Kochkarev Dmytro , Galinska Tatyana , Tkachuk Oleksandr
Published: July 2018

The basic principles of the normal sections calculation of reinforced concrete and fiber reinforced concrete bending elements are considered. In the article the power and deformation methods of calculation of reinforced concrete and fiber concrete elements of rectangular cross-section are presented. The deformation model of the calculation of reinforced concrete and fiber concrete elements is presented in the framework of the method of calculation resistance of the section. This method makes possible from the common methodological positions to perform calculations of reinforced concrete and fiber concrete elements. Namely, to select reinforcement and to determine the carring capacity. The proposed deformation model for calculating fiber concrete elements is based on generally accepted preconditions. A hypothesis of plane cross sections is accepted as fair. The deformation diagram of compressed concrete is described by a nonlinear function with established parametric points. Distribution of stresses in stretched concrete is taken rectangular with corresponding coefficients which are taken depending on the type of deformation diagram. Determination of the carring capacity of fiber concrete elements occurs under extreme deformation criteria. Two cases of destruction of the investigated elements are considered. The first case is the destruction due to the achievement of limiting deformations in the concrete of the compressed zone with the simultaneous achievement of the fluidity limit in the working reinforcement. The second case is the destruction due to the achievement of limiting deformations in the concrete of the compressed zone without reaching the fluidity limit in the working reinforcement. Both cases of calculation are reduced to one functional dependence. This avoids the delimitation of different calculation cases. The main no dimensional modifier is the mechanical coefficient of reinforcement. According to the developed method, examples of calculations of reinforced concrete, fiber reinforced concrete elements and fiber concrete elements with longitudinal reinforcement are executed. The possibility of a spread variant design of reinforced concrete and fiber concrete elements is shown.

Authors: Semko Volodymyr , Leshchenko Maryna , Cherednikova Oleksandra
Published: July 2018

The paper provides analysis of the state of the building envelope thermal reliability issue in Ukraine. It has been found that ensuring the reliability of the building envelope results only in economic losses and is not related to human losses, and therefore the question of normalization of no-failure performance probability of the construction upon the criterion of insufficient value of the reduced total thermal resistance is purely economic. The paper develops normalization of the required level of building envelope no-failure performance probability upon the criterion of reduced total thermal resistance. The suggested method of the required level standardization of building envelope no-failure performance probability upon the criterion of insufficient value of the reduced total thermal resistance of building envelope is proposed for the developers of normative documents, state standards, company standards or technical specifications. Designers should use only the calculated and average values of the minimum permissible thermal resistance, specified in the above-mentioned documents.

Energy Efficiency of “Green Structures” in Cooling Period
Authors: Tetiana Tkachenko , . .
Published: July 2018

The proposed methodology for estimating the reduction of CO2 emissions by green constructions (green roof and facade greening) due to the “cooling effect” during the cooling period allows to calculate CO2 savings in warm periods of the year. For Kyiv, in July, the reduction of CO2 emissions per m2 at coal using is 133 g / m2, during the warm period of the year – 515 g / m2; using gas – 78 g / m2 and 303 g / m2. It is established that the energy savings of a green roof depends on the thickness of the thermal insulation of buildings: the thicker insulation causes the less green roof contribution to energy savings. However, the significance of their effectiveness remains. Green roofs can be especially effective in switching from gas to local solid fuels: peat waste, pellets, etc. As a practical recommendation, it is proposed to coordinate the placement of greened and ungreen parts of the green roof with rooms under the roof, which allows to reduce the refrigeration load on air conditioning. In addition, recommendations on grass care on the green roof have been developed. To maximize the cooling effect, it is necessary to maintain grass height no more than120 mm. Before the beginning of the transition period, it is necessary to stop mowing the grass, which reduces the cooling effect.

Published: July 2018

In the modern conditions, energy efficiency is one of the most important world problems. One of the important factors influencing the overall energy efficiency of buildings is air distribution in rooms. Literature review shows different options of efficiency estimation of air exchange with significant limitations. Some of them have non-obvious physical meaning. Certain of them do not take into account possible room zoning. Consideration of turbulence intensity in the efficiency estimation was not found. In this work, we propose an approach to estimate the air exchange efficiency in different kind of rooms. It is a relation of minimum room demands and inlet air potentials. Additional definitions are introduced for the parameters and demands estimation. The mechanical energy of the air is used for the estimation, which includes the energy of averaged motion and turbulent pulsation. Special approach is offered for turbulence intensity computation for energy calculations. The example of efficiency estimation of air exchange in a museum room with constant air volume system of air conditioning is solved.

Published: July 2018

An effective way of improving the properties of naturally occurring soils for pavement construction is by using geo-synthetics. In many tropical countries, weak lateritic sub grades are common and often rejected after proof rolling during construction due to poor strength. The main aim of this research was to check the effect of geo-grid reinforcement  on  CBR value on a sample of relatively Red soil subgrade  under soaked and Unsoaked conditions and to Establish the effect of geogrid reinforced subgrade on the design thickness of low volume paved roads. Even though Red Soil has high strength but if we apply geogrids results going to be checked. Then by placing a layer of a Bi-axial geogrid at different heights like one layer at h/2, two layer at h/5 top and bottom ,three layers at h/6 top, bottom and middle , the effects of geogrid reinforcement on California Bearing Ratio values are investigated. This was undertaken for three strengths of geogrid and without geogrids in both soaked and Unsoaked conditions. The CBR values were used to determine the pavement thicknesses. The results indicate that the pavement thickness is reduced by 21.31% by using double layer in the Soaked condition i.e. Worse condition.
A Novel Energy-Efficient Routing with Adaptive Receiver Using Cross-Layer Design in Wireless Sensor Networks
Authors: Abinaya R , Bhuvaneshwari C , Gayathri R
Published: July 2018

The increasing demand of wireless sensors in mission critical applications renders the Quality-of-Service (QoS) to be one of vital issue in wireless sensor network. It is necessary to deal with the underlying variance between energy efficiency and QoS, since sensor networks have different resource constraints. To manage these constraints such as unreliable links, limited power and other environmental factors in sensor networks, cross-layer approach is designed to ensure QoS. Recent routing protocols rely on the duty-cycle which causes sensor nodes to lose ample amount of energy by monitoring idle channels. In addition, opportunistic forwarding of packet leads to multiple receiver’s receiving the same packet which induces redundancy. To address these issues, we propose a novel Opportunistic Routing with Adaptive REceiver (O-RARE) protocol as an alternative to duty cycle mechanism. The proposed work aims at reducing idle listening and redundancy by enabling low-power receiver at physical layer. Hence O-RARE is designed to ensure reliable and adaptive routing in our work through interactions among cross-layer.

A mobile Ad Hoc network is a Noinfrastructure networkand randomly moves nodes are presented .Multicasting support data forwarding, and thus it is suitable for MANETs.Implementing’Multicast opportunistic cooperative routing in Mobile Ad Hoc Network’, (MANET) to improves the %PDR , and reduces the power consumption, multicast is meant for group communication. Multicasting sending copy of the information to all members in a group, it improves, the wireless link in a network.In an Ad Hoc network nodesare randomly distributed and free to fly without any existing infrastructure or infrastructure less administration. In the Networkeach node isfitted out with a single omnidirectional antennaand that multiple nodes are allowed, together their transmissions to take the advantages of spatial diversity to obtain energy savings.It is assumed that some nodes are not a member in a group, hence it does not receive transmission, and packet has be resent again. Where as in existing unicast transmission protocol for multiple hop network picked by multiple intermediate nodes,and only one receiver. Theprotocol performance is analyzed using the ns-2.32 network simulator.

This paper proposes a unique micro-strip patch antenna which has a hexagonal fractal pattern which can mainly be used for ground based surveillance radar applications. To further optimize the functioning of the antenna, multiple slots have been added to the ground plane, and a stepped pattern has been implemented to increase the current density and the gain. A detailed study of the stages of development of the antenna has been made, illustrating the effect that various design elements have on the operating characteristics of the final design. There is specific emphasis on the use of slots in the ground plane. Variations in return loss, gain, VSWR, operating frequency and bandwidth with changes in the design of the ground plane have been documented. The antenna is designed to perform in the X-band, more specifically around 9 GHz, making it well suited for short range search. The final iteration of the antenna design, including various stages of slotting in the ground plane, works at 8.7 GHz, which is well within the X-band range, and has a return loss of around 30 dB.

With a spurt in the use of non-conventional energy sources, photovoltaic installations are being deployed in several applications such as distributed power generation and standalone systems. Solar Photo Voltaic (SPV) module is the basic component of the solar PV system. The functioning of a photovoltaic array is influenced by solar insolation, shading and array arrangement. Often the PV arrays get shadowed, completely or partially by neighboring buildings, trees, towers and service poles. The efficacy of PV array unvaryingly depends upon temperature which in turn is reliant on radiation. In order to validate this hypothesis, there are certain instruments and experimentation methods available which are expensive. But carrying out hardware testing on the solar PV system with Photo Voltaic Training and Research (PVTR) system and simulating using software will lead to least economical method of achieving performance analysis which is the main objective of this paper.  The efficiency of PV module is analyzed from I-V and P-V characteristics for this standalone solar pv system by changing radiation and temperature parameters. This paper mainly emphases on comparison of the testing results and simulation results for different radiation levels.

Published: July 2018

Power transformer is costly and very important equipment in power sector. Failure of power transformer causes colossal damage to the power system. One of the important reasons for transformer failure is event of Partial Discharge (PD) in the transformer. Numbers of non-conducting and conducting particle are available in the transformer. Conducting particles available in the transformer or mineral oil entering into winding space, strike the energized winding of the transformer cause PD to occur. Movement pattern of particle administrates the probability of particle striking the winding. Analysis of movement of particles proximate to HV winding helps in understanding the occurrence of PD. This paper deals with tracking of aluminum and copper particles of various sizes available inside the transformer.
