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.","PeriodicalId":221366,"journal":{"name":"Modern technology, materials and design in construction","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130085795","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}

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.","PeriodicalId":221366,"journal":{"name":"Modern technology, materials and design in construction","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132167143","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}

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.
