However, THM often have to move along those very roads. Purpose of the study: We aimed to increase the movement smoothness of THM on a vehicle chassis by using a shock absorber of new design as the main vehicle undercarriage suspension element. Methods: The hydropneumatic shock absorber is considered the most common. The principle of its operation is based on hydraulic resistance that occurs when the piston with the rod move in a space filled with oil, while the gas in the closed part is compacted, compensating for changes in the internal volume. Most often, the main disadvantage related to the operation of hydropneumatic shock absorbers (HPSA) is the probability of bottoming when hitting a barrier (obstacle), which results in dynamic loads reducing the service life of the vehicle and the parts of the shock absorber. Results: The paper describes a new shock absorber design ruling out bottoming, provides a mathematical model of its elastic response, and presents the results of modeling in Mathcad, confirming the operability of the device.","PeriodicalId":52295,"journal":{"name":"Architecture and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44433791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Purpose of the study: We aimed to investigate the impact of external window shading on thermal performance of three existing residential buildings having different forms (rectangular, L-shaped, and U-shaped) in hot-dry climate in Amman, Jordan. Methods: Three types of shading, namely: vertical, horizontal, and combined, of different lengths (0.75 m, 1.00 m, and 1.25 m) were introduced to the existing buildings. The effect of those types of shading was studied using the OpenStudio SketchUp 2020 plugin and EnergyPlus simulation program. Results: It was established that vertical shading slightly improves the indoor air temperature in all building forms, while horizontal shading and combined shading improve the thermal performance of buildings to a more significant extent. Combined shading of 1.25 m in length shows the optimum behavior in all buildings since it reduces the indoor air temperature in the range of 2.6–3.3°C. Besides, it improves thermal sensation, which seem to be closer to the comfort zone, by reducing the predicted mean vote (PMV) and predicted percentage of dissatisfied (PPD) values as compared with the baseline situation without shading. In addition, the rectangular building demonstrated the best response for shading by showing the largest reduction in the indoor air temperature.","PeriodicalId":52295,"journal":{"name":"Architecture and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49504353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In it, the functions and duties performed in the built environment by architects, construction workers, civil engineers, surveyors, sculptors, decorators, etc., are all lumped together into either architecture or civil engineering. However, for civil engineers, who operate both in built and unbuilt environments, the scope and depth of subjects covered by this work could serve as useful resources as they develop their competences in core practical aspects of civil engineering. Materials and Methods: This paper explores Ten Books on Architecture in relation to civil engineering in the 21st century. The materials used for this work were obtained from internet sources, university libraries, textbooks, write-ups and commentaries that were purchased from open markets and bookshops. Results: The review shows that: (i) the profession of the architect, used in the times of Vitruvius interchangeably with the civil engineer and town planner, as well as the very concept of architecture or civil engineering, in terms of social standing, differs significantly from the present times; (ii) most of the projects discussed in the book form the core of what is classified in the 21st century as civil engineering; (iii) civil engineers ought to be versatile in the art solving of problems that may arise during the course of construction, both in the built and unbuilt environments; and (iv) the buildability issues of civil engineering make knowledge of how to assemble simple construction equipment a necessity. Conclusion: Though not recommended in the curriculum, a working knowledge of either Latin or Greek will help to make the book an indispensable companion for structural and civil engineering practitioners and also enhance their performance capacity.","PeriodicalId":52295,"journal":{"name":"Architecture and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42749721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is mainly associated with a reduction in the rigidity of road pavements made as extended multi-layer structures. To identify the causes of rigidity reduction, non-destructive testing is used, which is based on solving the inverse coefficient problem of restoring the elastic constants based on the response on the surface. Purpose of the study: We aimed to provide a rationale for a new pavement condition indicator that would take into account the history of deformation and loading from a source on the surface, based on which it would be possible to solve the inverse problem of restoring the elastic and viscous characteristics of pavement layers. Methods: To do that, we performed mathematical modeling of the stress-strain state of a multi-layer medium based on the solution of a system of dynamic Lame equations. Viscosity is taken into account by introducing tangents of the angles of wave energy losses in the materials of layers. Results: The results obtained in modeling for the first time made it possible to establish the relationship between changes in the modulus of elasticity as well as tangents of the angles of energy losses in pavement layers and the amount of energy dissipation in the structure. Discussion: It should be noted that it is possible to switch from the bowl of maximum dynamic deflections as the main pavement condition indicator to the analysis of hysteresis loops on the road structure surface, recorded at different distances from the point of load application and being an analogue of the full bowl of dynamic deflections showing the history of the test object loading.","PeriodicalId":52295,"journal":{"name":"Architecture and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46433715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methodology: We carried out a bibliometric analysisand a systematic review of UER in accordance with AI concepts, models, and applications. Results:The findings of this study were used to create an integrative framework, based on three hierarchical phases, which effectively addressed the main capabilities of UER, identified its priorities, and shed light on how ML can benefit UER as a whole.

Purpose of the study: We aimed to develop effective repair compounds obtained by activating the original components. Methods: To process the original components, low-temperature non-equilibrium plasma (LTNP) and electromagnetic activation in a vortex layer device were used. In the course of the study, we used polypropylene, steel, glass, and basalt fiber and fiber made of structured ferromagnetic microwire. Electron microscopy and X-ray diffraction analysis were applied. Results: It was established that the combined use of the above methods for the modification of raw components makes it possible to improve the strength of these materials by more than 50%, which is due to the characteristics of structure formation in the developed compositions. For instance, LTNP increases the amount of portlandite and reduces the main phases of cement stone— C3S and β-C2S, and vortex activation contributes to an increase in the total number of crystalline phases. Quartz powder particles processed in an electromagnetic mill are characterized by layered structure, high surface roughness, large developed cracking, as well as inclusions as a result of impact action. All that improves the physical and mechanical properties of the resulting repair compositions by an average of 20%. Repair compositions additionally treated with plasma modification feature new hydrated formations on quartz grains.","PeriodicalId":52295,"journal":{"name":"Architecture and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47777517","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Updating this housing to meet the current habitability requirements, as well as enhancing and transforming it into high-quality 21st century residential buildings, is a task that cannot be postponed. Purpose of the study: The issues of energy efficiency, habitability and accessibility are very salient today, so it seems pertinent to recover relevant examples of 20th century architecture and investigate to what extent the parameters with which they were designed are still valid. Methods: This paper reviews housing case studies in two neighborhoods, Poblado Dirigido de Fuencarral and Colonia Juan XXIII de Carabanchel, comprehensively analyzing the original buildings and their current rehabilitation. This includes comparing the buildings’ energy efficiency before and after the intervention carried out. Approach: This study verified that in both cases, an attempt was made to recover several elements of the original design during rehabilitation. Results: We found that both projects were originally committed to creating an open, pedestrian-friendly city with abundant vegetation, which is still a valid value today. Despite the economic restrictions at the time of construction, both projects used advanced energy strategies, such as the passive design offered by cross ventilation, the unusual thermal insulation envelope, or the efficient district heating. Novelty: In addition, this paper aims to incorporate the heritage of the great mid-20th century architect José Luis Romany, author of both projects, into modern Spanish architecture.","PeriodicalId":52295,"journal":{"name":"Architecture and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48284322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
