This paper presents a simple incremental approach of analysing the static behaviour of functionally graded tapered beams. This approach involves dividing the non-uniform beam into segments with uniform cross-sections, and using two separate finite element models to analyse the structural behavior of slender beams (Euler-Bernoulli model) and deep beams (Timoshenko beam theory). The material properties of the beam vary according to a power law distribution through the thickness, resulting in smooth variations in the mechanical properties. The finite element system of equations is obtained using the principle of virtual work. Detailed information on the shape functions and stiffness matrix of the beam is provided, and the numerical results are evaluated and validated using data from the literature. The comparison demonstrates that the response of the functionally graded tapered beams is accurately assessed by the proposed approach. Additionally, the effects of material distribution, boundary conditions, and tapering parameter on the deflection behavior are presented. Results show that an increase in the power law index increases the flexibility of the functionally graded tapered beams, resulting in higher deflection. Furthermore, lower tapering parameters also result in higher deflection. Compared to other boundary conditions, clamped-clamped boundary conditions demonstrate the best performance in terms of maximum deflection.

This study deals with the condition examination of elementary school buildings in Primorje-Gorski Kotar County, Croatia. For schools to be functional and of high quality, adequate maintenance is mandatory. Therefore, school maintenance programs need information on the building's condition based on systematic and comprehensive assessments as a primary input. This study aims to establish a framework for assessing the condition of school buildings, based on which information can be obtained quickly and practically regarding the condition of all critical facility elements. To this end, a database on schools and their conditions was created. The conditions of school buildings in terms of damage and defects and their causes were determined. Descriptive and inferential statistical operations were performed on the collected data. A condition assessment of the buildings was performed using a questionnaire survey among the principals, based on the school buildings division model developed in this study; the model presents building elements and a systematic visual condition rating scale. According to the available data, this is Croatia's first condition assessment on elementary school buildings. The main results show that on average, the examined schools are in good condition. Moreover, according to the results, the school building condition is most affected by dilapidation and lack of financial resources.

Fluoride ions (F-) from natural sources or industrial wastewater are the main cause of many pathological conditions in people living in more than 25 countries. Thus, removing F- from drinking water is pivotal for preventing serious health consequences. The WHO recommends a limit of 1,5 mg/L for fluoride in drinking. Excessive amounts of fluoride in drinking water are prevalent in Pakistan, leading to related health risks. Low-cost techniques for the defluoridation of drinking water can be used. In this study, the removal of fluoride from drinking water by an adsorption method using low-cost materials/adsorbents, such as marble chips, wheat husks, rice husks, egg shells, concrete, fuller earth, fly ash, freshly fired bricks, and charcoal, at different contact times and different bed thicknesses were investigated. A batch sampling technique was used for sample collection. On average, marble chips, wheat husks, rice husks, egg shells, concrete, fuller earth, fly ash, freshly fired bricks, and activated charcoal (rice husk) resulted in 71,99 %; 90,99 %; 66,73 %; 90,99 %; 63,30 %; 71,99 %; 22,60 %; 49,67 %; and 90,13 % fluoride removal, respectively. Therefore, defluoridation using these materials is desirable. The performance of adsorbents depends on parameters such as contact time, depth of the adsorbent media, and pH. The bed thickness of the adsorbent has a minor effect on fluoride removal. The major contributors to fluoride removal from water are contact time and adsorbent composition.

This study analytically investigates the behaviour of trapezoidal infilled frames (TIFs) with brick masonry infills having openings and various interface materials between the brick panel and reinforced concrete frame. Single-storey single-bay frame specimens are analysed under in-plane static loading. For this investigation, the optimum angle of the column inclination for the trapezoidal frame must be determined in terms of maximum lateral stiffness. The optimum angle must be further analysed and compared with rectangular bare and infilled frames, with various materials of the interface. This infilled frame is extended to analyse the openings in the infill further. To study the effects of openings in infilled panels, TIFs with different sizes and positions of window openings are analysed and compared with the rectangular frame. This study further analyses three different combinations of interfaces and determines the intermediate stiffness of the frame combination. The main focus of this investigation is to reduce the high rigidity of the TIF leading to high base shear. It is found that, the infilled frame is stiffer than the bare frame, and the cement mortar interface is stiffer than the lead–cork interface. This research uses ABAQUS software, a finite element analysis program, for expanding the observational analysis.

Rice husk ash (RHA), owing to its pozzolanic properties and wide abundance, is an additive that can be used as an alternative to cement to improve a variety of soils. Damping and shear modulus are two important soil dynamic parameters used to predict soil behaviour under dynamic loading. Therefore, in this study, materials were prepared and their specifications were determined. A cyclic triaxial device was used to determine the dynamic parameters (stress control). Subsequently, the results related to shear modulus and damping calculated for pure sand before and after stabilisation were analysed according to different percentages of stabilisers for two frequencies of 0.5 and 1 Hz. The results revealed the effect of different frequencies on the damping of pure sand, which differed for stabilised sand. In all stabilised specimens, the shear modulus decreased with increasing frequency. Additionally, the damping decreased with increasing frequency in the stabilised samples. The shear modulus increases with the increase in the amount of stabilisers. The results also showed the positive effect of partially replacing cement with RHA.

This research analysed the impact of road alignment on the fuel consumption and gas emissions of a vehicle driven at a free-flow speed by an 85th percentile driver. The field experiment included constant and free-flow speed rides by a personal car equipped with a high-performance (10 Hz) Bluetooth global position device and on-board diagnostics connector, with which the travel path, speed, acceleration, and consumption data were recorded. Regression analyses of the dependence of free-flow speed and fuel consumption on the geometric characteristics of the road (curvature, length, longitudinal slope, etc.) resulted in the formation of a reliable model that could compare alternative road designs for a given corridor in terms of route economy and safety. The main parameters contributing to the consumption on tangents were the slope and radii of adjacent curves. For constant speed, the slope was the only geometric parameter that had an impact on fuel consumption.

Crude oil and its products are strategic and vital goods for most countries in the world. It is necessary to store these products in the production and transfer chain and send them to refineries, ports, and airports for military and national purposes. Lightweight concrete is propounded as a useful replacement for normal concrete due to its low specific weight and acceptable resistance property; however, compared to normal concrete, it is considered to be more permeable, less durable, and less resistant. Therefore, in this study, the reliability of this synthetic material in oil conditions has been investigated. In this regard, two groups of samples were investigated under normal and oil environmental conditions, polymer Kortta fibres with percentages of 0; 0,5; 1,0; 1,5; and 2,0 % and microsilica with percentages of 0 and 15 % by cement weight were incorporated alone and combined. Subsequently, tests were performed on the specimens after 90 days. The results showed that the combination of microsilica and Kortta fibres causes a significant increase in lightweight concrete strength and impermeability.

Global warming leads to significant long-term changes in climate loads and effects on structures, which must be considered when designing buildings. In this study, loads on buildings and structures were examined to evaluate long-term changes in temperature and humidity of the atmospheric air and to develop a method for forecasting the estimated values of these effects. According to the data obtained via weather stations in Ukraine, it was determined that long-term changes in thermal and humidity actions at different weather stations are qualitatively similar but vary numerically by a significant extent. The increase in air temperature is generally consistent with the known trend of global warming, and relative humidity is characterized by a decrease in the variance at almost constant average annual value. The proposed method of identifying and describing trends in long-term changes in climatic influences can be used in the development of regulatory documents and in directly designing buildings and structures by considering the predicted changes in climatic influences during the future life of buildings.

The aim of this study was the verification of unmanned aerial system (UAS) application in vehicle swept path analyses by analysing the advantages and disadvantages and comparing field test results with two software solutions. In this study, swept-path analyses were performed for two vehicle types and two turning angles. UAS images were used to extract the vehicle swept path and the results were compared with two commonly used swept-path analysis software. The results indicated larger deviations between the swept paths for an angle of 125° for a light truck. For both analysed vehicles and turning angles, larger deviations were observed for the outermost point trajectory. Passenger cars occupy less space performing 125° turns than software analysis predicts, indicating that they are on the safe side when designing vehicle manipulative surfaces. For the analysed light truck, a larger turning radius was observed than the predicted for a 125° turning angle, which may be caused by the approaching and turning speeds under which the test was performed. Finally, while the UAS recording process is relatively simple and fast, data processing is demanding and time-consuming. To fulfil its full potential within swept path analyses, UAS needs to be complemented by proper data analysis software solutions for faster and more accurate swept path extraction, which would improve and rationalise the traffic area designing process.

Current research and documents on urban development emphasise the links between economic growth and planning strategies, making urban space an asset of the contemporary market economy. The analysis of development trends in post-transitional cities shows numerous similarities to the Asian concept of developmental cities. This study examines current urban development strategies in the city of Novi Sad (Serbia), particularly focusing on trends in housing projects, which are the major contributors to the production of urban space. The housing policy in the city, spanning from urban reconstruction after WWII until the present, is comprehended through statistical data on construction activity, taken as an indicator of change in urban politics and the general concept of city development. The major change in this concept is the weakening of the connection between city population growth and apartment building production. As a result, human needs are no longer the primary motive for apartment construction. The comparison, analysis, and conclusions based on the interpretation of the indicators highlight the necessity for rethinking present urban practises in order to combat the continual process of degrading the quality of life in the city.
