The relevance of paying attention to the energy efficiency of buildings, which will reduce the consumption of fossil fuels and electricity and reduce harmful emissions into the environment, is shown. The energy efficiency indicators of the public building were analyzed, namely the thermal resistance of the enclosing structures, the specific energy demand for heating, cooling and hot water supply, the specific energy consumption of the building for heating and cooling, the specific consumption of primary energy and the specific emissions of greenhouse gases.The effect of increasing the normative thermal resistance of the outer wall of the building on the required thickness of the insulation was evaluated. It is indicated that under the conditions of a large facade glazing ratio and compliance with the regulatory thermal resistance of the fences, the building does not meet the requirements for specific energy consumption for heating, cooling and hot water supply.The influence of the heat source for heating the building on its specific energy consumption, energy efficiency class, specific consumption of primary energy and specific emissions of greenhouse gases was studied. Considered options for using a gas boiler, a condensing gas boiler, electric heaters, a biomass pellet boiler and connection to a centralized heat supply system. The effectiveness of the implementation of reversible heat pump equipment for heating and cooling of buildings is substantiated

The increase in the number of people living in cities leads to an increase in the number of transport and the emergence of transport problems, such as traffic jams, air pollution and the lack of a sufficient number of parking spaces. To effectively manage urbanization processes, sustainable and innovative approaches to urban planning, infrastructure construction, access to housing, education and health care need to be developed. Creating an efficient system of public transport, green zones, stimulating sustainable consumption and energy efficiency are important steps towards sustainable urban development.Increasing the flow of vehicles, in the process of urbanization, leads to a decrease in the quality of life for residents of settlements and makes our cities less attractive to tourists. Such problems are especially threatening for cities with limited territory or with historical buildings, where narrow streets and the lack of a sufficient number of car parks complicate the situation. However, proper planning and management can help cities become more viable and comfortable to live in, ensuring a high quality of life for residents.So, to implement rational methods of dealing with transport problems of our time at the regional level, it is worth turning to successful examples of world society.
城市人口的增加导致交通工具数量的增加和交通问题的出现,如交通堵塞,空气污染和缺乏足够数量的停车位。为了有效管理城市化进程,需要制定可持续和创新的城市规划、基础设施建设、获得住房、教育和保健的办法。建立高效的公共交通系统、绿化区、刺激可持续消费和提高能源效率是实现可持续城市发展的重要步骤。在城市化的过程中,车辆流量的增加导致住区居民生活质量的下降,使我们的城市对游客的吸引力下降。这类问题对领土有限或有历史建筑的城市尤其具有威胁性,这些城市狭窄的街道和缺乏足够数量的停车场使情况复杂化。然而,适当的规划和管理可以帮助城市变得更加可行和舒适,确保居民的高质量生活。因此,为了在区域一级执行处理我们时代交通问题的合理方法,有必要参考世界社会的成功例子。

The paper contains the methods of analytical modeling of the seismic loads at the large-sized tanks in the form of impulsive and convective hydrodynamic pressures of the liquid. Have been performed the simulation of the stress-strain state of the tank by the finite element method basis on the developed mathematical models of seismic impact. The simulation takes into account the distortion of the tank’s geometry, obtained as a result of long-term operation and reduction in the strength of tank structures due to corrosive wear. Have been considered the generally accepted foreign method for calculating seismic resistance for assessing the strength and durability of tank’s building structures. The method is adapted to the requirements of national standards. Have been revealed that the most dangerous state for the tank is seismic action with a horizontal direction cosine as a result of the analysis of possible design situations. Have been performed the numerical calculations using the proposed method of analytical modeling of seismic impact for a tank with a volume of 20 000 m3, built in the Yuzhny city, Odessa region. Have been determined the estimated height value of the excited wave, which can appear on the surface of methanol during a seismic shock. Have been proven that in order to preserve the integrity of the roof structures, as well as to ensure the seismic resistance of other structures, the filling of the tank with the product should be limited to 61% of the total design capacity. Have been verified the most overloaded sections of the shell, which are the supporting layers of the side wall, as well as the most probable limit conditions during a seismic shock (buckling).Have been developed the technological regulations for further safe operation of tank based on seismic resistance and outlined directions for further scientific research on this topic.
本文介绍了大型储罐地震荷载以液体的脉动和对流动水压力形式进行解析建模的方法。在建立的地震冲击数学模型的基础上,用有限元法对储罐的应力-应变状态进行了模拟。模拟考虑了由于长期运行和腐蚀磨损导致的罐结构强度降低而产生的罐的几何变形。已被认为是国外公认的用于评估储罐建筑结构强度和耐久性的抗震计算方法。该方法符合国家标准的要求。通过对可能的设计情况的分析,揭示了储罐最危险的状态是具有水平方向余弦的地震作用。采用提出的地震影响分析建模方法,对敖德萨地区尤日尼市一座容积为2万m3的储罐进行了数值计算。确定了地震冲击时甲醇表面可能出现的激波高度的估计值。实践证明,为了保持屋面结构的完整性,以及保证其他结构的抗震性能,储罐的产品填充量应限制在总设计容量的61%。已经验证了壳体的最大过载部分,即侧墙的支撑层,以及地震冲击(屈曲)期间最可能的极限条件。制定了基于抗震的储罐进一步安全运行的技术规程,并提出了进一步科学研究的方向。

The paper contains the further developed of method for calculating thin-walled dome systems without a stationary foundation. Have been carried out the detailed analysis of the fundamental design solutions for frameless collapsible spherical polycarbonate domes, which are used by modern world manufacturers of these structures. Have been done a brief description of the momentless theory of the operation of spherical shells, which is adapted for polycarbonate domes. Have been considered a simplified analytical model of the stress-strain state of a spherical shell with an equatorial diameter of up to 5 m under the influence of climatic influences for the subsequent verification of detailed models. Have been developed highly detailed finite element models of domes of different sizes, taking into account technological openings and structural stiffeners (support ring and door frame) under the wind, snow, ice loads and under other climatic influences. Have been identified the fragments with the highest stresses from various loads and forms of the deformation of the structure. Have been considered separately the issues related to the loss of shape stability, position and balance of a thin-walled spherical shell, as a light temporary structure. Have been proven that the worst influence on the dome structures is the wind influence, based on the stability criterion. Have been determined the estimated value of the aerodynamic lifting force from wind effects on the dome. Have been proven that the lifting force far exceeds the stabilizing force of the weight of a thin-walled dome. Have been revealed with the help of the performed calculations, it was that a frameless spherical polycarbonate dome inevitably loses its balance stability due to the action of wind loads and requires unfastening with anchors. Have been proposed a rational method for anchoring dome structures at temporary earthen construction sites using geo-screws or metal screw piles. Have been revealed the addiction between the radius of curvature of a spherical dome and the rational thickness of polycarbonate based on the criteria of stiffness and strength. Have been formulated the constructive recommendations regarding the rational design of polycarbonate dome systems. Have been developed the technological regulations for the further safe operation of domes, and have been outlined the directions for further scientific research on this topic.
本文进一步发展了无固定基础薄壁穹顶体系的计算方法。对现代世界制造商所使用的无框架可折叠球形聚碳酸酯圆顶的基本设计方案进行了详细分析。简要介绍了适用于聚碳酸酯圆顶的球壳无力矩运行理论。在气候影响下,赤道直径达5 m的球壳应力-应变状态的简化分析模型被认为是后续详细模型验证的必要条件。考虑到风、雪、冰荷载和其他气候影响下的技术开口和结构加强筋(支撑环和门框),开发了不同尺寸圆顶的非常详细的有限元模型。已经确定了从各种荷载和结构变形形式中具有最高应力的碎片。分别讨论了作为轻型临时结构的薄壁球壳的形状稳定性、位置和平衡损失的相关问题。根据稳定性准则,证明了对穹顶结构影响最大的是风的影响。确定了风对穹顶的气动升力的估计值。已经证明,举升力远远超过薄壁圆顶重量的稳定力。通过计算发现,由于风荷载的作用,无框架球形聚碳酸酯圆顶不可避免地会失去平衡稳定性,需要用锚来解开。提出了在临时土工场地采用土工螺钉或金属螺旋桩锚固圆顶结构的合理方法。揭示了基于刚度和强度准则的球形穹顶曲率半径与聚碳酸酯合理厚度之间的依赖关系。对聚碳酸酯穹顶系统的合理设计提出了建设性的建议。制定了穹顶进一步安全运行的技术规程,并对该课题的进一步科学研究方向进行了概述。

Have been carried out the detailed analysis of the fundamental design solutions for frameless collapsible spherical polycarbonate domes, which are used by modern world manufacturers of these structures. Have been done a brief description of the momentless theory of the operation of spherical shells, which is adapted for polycarbonate domes. Have been considered a simplified analytical model of the stress-strain state of a spherical shell with an equatorial diameter of up to 5 m under the influence of climatic influences for the subsequent verification of detailed models. Have been developed highly detailed finite element models of domes of different sizes, taking into account technological openings and structural stiffeners (support ring and door frame) under the wind, snow, ice loads and under other climatic influences. Have been identified the fragments with the highest stresses from various loads and forms of the deformation of the structure. Have been considered separately the issues related to the loss of shape stability, position and balance of a thin-walled spherical shell, as a light temporary structure. Have been proven that the worst influence on the dome structures is the wind influence, based on the stability criterion. Have been determined the estimated value of the aerodynamic lifting force from wind effects on the dome. Have been proven that the lifting force far exceeds the stabilizing force of the weight of a thin-walled dome. Have been revealed with the help of the performed calculations, it was that a frameless spherical polycarbonate dome inevitably loses its balance stability due to the action of wind loads and requires unfastening with anchors. Have been proposed a rational method for anchoring dome structures at temporary earthen construction sites using geo-screws or metal screw piles. Have been revealed the addiction between the radius of curvature of a spherical dome and the rational thickness of polycarbonate based on the criteria of stiffness and strength. Have been formulated the constructive recommendations regarding the rational design of polycarbonate dome systems. Have been developed the technological regulations for the further safe operation of domes, and have been outlined the directions for further scientific research on this topic.","PeriodicalId":221366,"journal":{"name":"Modern technology, materials and design in construction","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124866447","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}
