Published: November 2019

Abstract
The issue of quality control of construction products requires close attention in the paradigm of modern management, focusing on this aspect of it — the costs of investment and construction activities and their impact on the performance of the corporate level, identifying those groups of costs for ensuring the quality of construction products that can be foreseen and excluded. Within the framework of modern economic concepts, it is very difficult to verify the concept of costs of ensuring product quality (including construction), because in one way or another all activities related to the production of products are related to its quality. This fact makes it difficult to accurately define the concept of the cost of ensuring product quality, since there is no difference between the costs of ensuring product quality and the costs of other activities. The article addresses the need to form a common system of methods, criteria, indicators for assessing the cost of quality assurance, as well as organizational structures for making organizational and technological decisions to ensure the quality of construction and regulatory and analytical support for this kind of activity at the corporate level.
Influence of the Inlet Size on the Natural Ventilation System Operation in a Residential Multi-storey Building
Authors: Malyavina Elena , Agakhanova Kaminat 
Published: November 2019

Abstract
When equipping the buildings with tight windows, the designers are required to take into account the aerodynamic resistance of the supply devices. The apartment plans, which became much more complicated over the past twenty years, resulted in increasing the number of prefabricated ducts of natural exhaust ventilation systems in each apartment of a residential house. Aerodynamic calculations of each exhaust system shall consider the ventilation paths starting from the outside air in the supply unit of a living room and ending above the exhaust shaft of the system. The results were obtained on the basis of the air mode calculations of the building as a whole. In this article, the calculation of the building air mode has been carried out by the iterative method. The object of the study was a section of a residential building with 18 residential floors equipped with natural ventilation systems. The article considers two options of the air inflow: through the swing-out window sash with 0.231 m2 open area and through the supply valves in each room of the apartment with 0.0036 m2 live section of one valve. It has been shown that in case of insufficient area of supply devices it is impossible to provide the ventilation air design flow rate under design ventilation conditions even with the help of air ducts of unrealistically large sizes.

Published: November 2019

Abstract
The average percentage of high-rise residential buildings in Russia is approximately 5% from the general volume of house construction. However, the demand for this type of buildings begins to increase. This factor relates to establishment of coherent multifunctional living environment with complex infrastructure. All of this facts cause the problem of high-rise building construction, including the design of engineering systems. Building air mode is influenced by external pressures applied to the centers of air-permeable openings, including wind pressure. Wind speed increases in the height of the building, but this change is often neglected in multi-storey houses, of course it is necessary to take this phenomenon into account designing high-rise buildings. The article presents various methods of accounting wind speed change in height, which were calculated for different cities in Russia. According to the of wind speed results obtained, the specific rate of infiltration air has been calculated, which significantly exceed the values in the case of a constant speed.

Contamination of Soils and Sub-Soils at Construction Sites
Authors: Galitskova Yulia M. 
Published: November 2019

Abstract
Construction works, like any anthropogenic activity, have a negative impact on natural complexes. High levels of air, water and soil pollution are observed in areas of construction. This occurs at all construction stages: during the design and survey work, during the construction of roads and quarries, directly during the work on the construction site. Each stage of construction results in a new pollutant appearing each time. The greatest problem is the contamination of soils and sub-soils: soil dumps on construction sites, using bulk construction supplies, storing various supplies on the construction site, washing off bulk materials into the areas adjacent to the construction site, and the contamination of soil with fuel. The paper presents the results of the study describing the process of penetration of oily liquids, exemplified by kerosene, diesel fuel and gasoline. Studies were conducted in the laboratory. Sand is used as soil in accordance with the similarity criterion. Each type of fuel underwent series of tests with different volumes 50, 100 and 150 ml. The minimum number of tests in the series – 6. The minimum testing time for each series – 24 hours. The results of the study were analyzed and presented in the form of tables and graphs. The study revealed the following. Initially, the process of penetration is the same for all liquids tested. With the minimum tested volume, the average penetration depth for gasoline was 16.7 cm, for kerosene – 12 cm, and for diesel fuel – 21.5 cm. With the maximum tested volume, the average penetration depths were 21 cm, 21 cm and 21.5 cm, respectively. The studies also showed that, at the initial period, diesel fuel penetrates the sub-soil more slowly compared to all other tested liquids. This is due to a higher level of viscosity. The paper considers ways to reduce the impact of soil contamination on biota, as well as ways to eliminate this negative impact, leading to an increase in the efficiency of land improvement works, which take place after construction.

Authors: Sitanyiova Dana , Misso Francesco Edoardo 
Published: November 2019

Abstract
Rural areas occupy substantial part of the entire EU’s surface area and rural development is an important policy area, covering among others also economic diversification in rural communities. Rural areas are important to the European economy as they provide foodstuffs, raw materials, or places for a wide range of recreational activities. However, some parts of these regions suffer from an ongoing population decline and dynamic aging as well as services of public interest retreat from these areas. This, however, cause enormous challenges for the provision of public services, such as public transport. The high costs of a traditional transport network and low level of demand make investments more difficult and ineffective for stakeholders in the mobility sector. The paper brings information on RUMOBIL project outputs from pilots testing new public transport services in sparsely populated peripheral areas. Results of these pilots were used to prepare recommendations presented in the form of the RUMOBIL Strategy, which provides an insight into already proven good practices and novel solutions.

Published: November 2019

Abstract
Czechoslovak Republic faced the serious need of dwellings for more numerous post-war generations in 50´s up to 70´s of the 20th century. New technology of the modular concrete high-rise apartment houses enabled an extensive mass construction. From 90´s of the 20th cent. increasingly more strict demands regarding thermal insulation properties were applied and the most frequently chosen technology to deal with them was ETICS added to concrete external walls. Interaction of various bird species and insulated façades, not limited to failure or damage, are interesting theme. This research deal with the nesting preferences of Delichon urbicum species in relation to the characteristics of architecture. The housing estate Solinky in Žilina in the northern Slovakia was a locality chosen for monitoring and analysis as housing estates belong to the important nesting/breeding grounds of the several bird species. In order to maintain ecological balance, necessary architectonical features should be provided as nesting sites in context of the topology of houses and paper identifies them. Future lies in solutions for coexistence of apartment dwellers and bird species in urban space.
Economic prospects of Steel Reinforced Functionally Graded Concrete (SRFGC) beam structures
Authors: Gan B S , Kiryu S , Han A , Pratama M M A 
Published: November 2019

Abstract
Engineering materials, for instance, ceramics and concrete, are manufactured with uniform properties purposefully. Because the uniformity is a convenient measurement to ensure the safety design calculation of a structure to be built. The non-uniform material property of concrete can be resulted from mixing, placing, consolidation, and curing processes during the manufacturing of structural members. Therefore, using concrete as a material could lead to an uneconomical use of natural resources because of non-uniformity problems that occur in the structural members. Ideally, in the Functionally Graded Concrete (FGC) material, the properties (elasticity, density, rigidity) of concrete material have to be smoothly graded in the projected directions (longitudinally, transversally, diagonally) by following a governing equation. Hence, FGC has significant advantages over the existing concrete materials in the prominence of cement optimization. In recent progress, many researchers have been studied the mechanical behaviors and production methodologies of FGC enthusiastically. In the state-of-the-art of the FGC developments, two objectives need to be achieved: 1. The manufacturing procedure of FGC material, and 2. The method of analysis to design FGC material. In current developments, the technologies for manufacturing FGC material are still not available for the practitioners. The objective of this paper is to present a method of analysis to design a Steel Reinforced Functionally Concrete Graded (SRFGC) beam element based on the SNI (Indonesian National Standard) of Structural Concrete Requirements for Buildings code 2847:2013. The effects of the non-uniformity of concrete strengths are incorporated into the analysis. Because of the crack-opening assumption in the tensile region of the concrete, the neutral axis position is no longer at the mid-height of the beam cross-section. Hence, an iterative technique has to be employed in the design. An iterative technique is necessary because the internal forces of the beam have to be calculated at the cross-section being designed. The application of the method of analysis is highlighted by designing various type of beam cross-sections, which show the economic benefits of SRFGC beam compared to both the normal and high strength concrete’s material.

Authors: Hsu H L , Halim H 
Published: November 2019

Abstract
Steel moment frames have been widely used for earthquake-resistant purposes. These systems possess significant ductility, however, excessive deformation due to the lower structural stiffness. In order to improve the behavior of moment-resisting frames when subjected to cyclic loads, a new design that combined steel curved damper and brace member was proposed in this study. The curved damper was cut from steel plate and was placed in the center portion of the brace member. The new device was attached to the frame and was used to dissipate energy throughout the load application. A series of loading tests on steel frames strengthened with the proposed design were carried out. The strength and energy dissipation capabilities of frames with and without the strengthening device were compared. It was found from the comparisons that the behavior of framed structures was significantly improved, thus justified the effectiveness of the proposed design.

Published: November 2019

Abstract
Rainfall is one of the factors of slope failures due to the intensity of rainfall that will seep and increase the moisture content of geo-materials. One of the important role in slope stability is matric suction. This study present the relationship between rainfall and suction of soil which induced the slope instability and the slope stability analysis involving a building which may cause by instability due to suction variation. The slope had separated into three parts which are top of slope, middle of slope and toe of slope. Every part has been inserted with three tensiometer with 0.3 m, 0.45 m and 0.9 m depth. Suction of soil on slope was carried out by using tensiometer. Intensity of rainfall was collected by using rain gauge which placed at open area which to compare with matric suction of soil. Several site and laboratory tests were carried out to identify the soil properties. Stability of slope was analyzed using Slope/w and Manual Calculation via input parameters collected from laboratory test and field test. Fellenius’ method was used to interpret the factor of safety for slope study. This includes the analysis of the factor of safety of slices at the selected area with its matric suction value. It was found that when the rainfall increased, the suction of soil decreased and affected to decrease of factor of safety. Hence, the constructed slope was suggested to be redesign to improve its safety factor.
Cracking behaviour of green lightweight concrete one-way slabs using medium K Basaltic Andesitic pumice and Scoria
Authors: Suseno H , Soehardjono A , Rachmansyah A 
Published: November 2019

Abstract
This paper investigates experimentally the cracking behaviour of green lightweight concrete one-way slabs where coarse aggregates comprised medium K basaltic andesitic pumice and scoria. Three points bending test was performed on 24 one-way slabs of both lightweight concrete with three compressive strengths and four reinforcement ratios, and 1 one-way slab of normal concrete as control. Responses consisted of crack width, mid-span reinforcement strain and mid-span deflection that were measured for observation purposes. To show the cracking behavior, their low tensile strengths were evaluated by representing their compressive strengths. Load versus crack width and reinforcement strain diagrams are simultaneously used to evaluate their cracking behaviors. Effects of reinforcement ratio, reinforcement stress, type of lightweight concrete and compressive strength to the maximum crack width are also investigated. Similarly, cracking patterns as well as failure modes are observed to show their appropriate performances. The results show that the reinforcement ratio and reinforcement stress are the main factors that affect significantly the cracking behavior and maximum crack width. However, the type of lightweight concrete and compressive strength affect them but less significantly. All one-way slabs exhibited a typical flexural crack, at the first time the reinforcement yields and then the concrete compressive zone crushes.

Abstract
The existence of springs cannot be obtained in each region; therefore it will be very detrimental if the presence of springs is not optimally utilized. This encourages Sumbercemung Villager, Wlingi Regency to take advantage of the potential of the existing spring. It is planned that in this area a tourist pool will be built using water sources. So there needs a research to support the developement of the pool. This study aims to determine the potential of ground water that will be planned for the location of pool. With the existence of this pool, it is expected to be a source of income for the Sumbercemung villager. This study was conducted by measuring soil resistivity using the Geo-electric method to determine the condition of groundwater around a spring. Analysis of geo-electric data uses Zondres software in 2D which is then analized in 3D using Voxler software. Based on the results of the analysis of groundwater from geo-electric data, no artesian aquifer were found in the location reviewed and only a water basin with a volume of 25291 m3 was found. Thus, the needs of pool water is filled with dependable flow.

This paper focuses on utilities that installed in and adjacent to the district’s road in Indonesia. The purpose of this paper is to explain the interaction framework of stakeholders involved, and the methods that are used to describe the relationship.
One day high-performance concrete mechanism of plate, beam, and column
Authors: Niken C 
Published: November 2019

Abstract
Plate, beam, and column have a different mechanical characteristic. Understanding the one-day mechanism of the three concrete structural elements is the objective of this study. The quality of the concrete used is fc’ of 60 MPa. Observation of concrete strain was done during 24 hours. Five small specimens measuring of 150 mm × 150 mm × 600 mm with one strain gauges (EVWSG) for each specimen, three specimens in horizontal position as a beam and two specimens in vertical positions as a column; one full-scale beam specimen measuring of 200 mm × 600 mm × 3000 mm (four EVWSG), and one plate specimen measuring of 3000 mm × 1600 mm × 150 mm (four EVWSG) were used. All specimens were covered with styrofoam. One-day behavior was found by computing the average strain change from a small beam and column specimens, and average strain change of the fourth EVWSG in the plate/full-scale beam. As a result, there is a similar type between concrete temperature and the behavior of plate, beam, and column. The behavior of the beam is identically to the plate behavior. Column behavior is more fluctuating than beam and plate. High rate shrinkage is significant in beam and plate, but in the column, expansion was dominated.
