  • Rationalization of technological, structural and architectural solutions of cable-stayed roofs of long-span stadiums

    The paper presents an analysis of stadiums with cable-stayed roof, in the context of progressive solutions used in various construction cycles. On the basis of the systematization carried out, the directions of the rational use of the identified methods of reducing material consumption and deformability, increasing the rigidity, stability of structures, improving the efficiency of installation work have been highlighted.

  • The process of progressive collapse of high-rise buildings and analysis of decisions that counteract it

    Modern construction industry is actively introducing new technologies and innovations in the field of high-rise buildings. This dictates certain requirements for the architectural and design features of the frameworks of buildings and the strengthening of foundations. It is necessary to give sufficient rigidity to the object in order to withstand external loads and impacts. All activities are aimed at ensuring the safety of people staying in a high-rise building. In recent decades, the construction of skyscrapers has increased, and such a notion as progressive collapse has become relevant. Therefore, the article examines and analyzes exactly progressive collapse as a problem requiring attention and a scientific approach to its elimination. The report concludes with some conclusions and recommendations.

    Keywords: progressive collapse, high building, security, the scheme of the framework, local area, rigidity, stability, dampening, external load, oscillation process, deformation

  • The main methods of increasing the stability and rigidity of large-span cable-stayed and hanging bridge structures

    The paper presents the systematization of the main methods for increasing the rigidity and stability of the cable-stayed and hanging types bridge structures , its given in conjunction with the analysis of the real objects. Among the methods presented are such techniques as: improving the quality of the material; additional structural elements that perceive vibrations; modification of the main elements of the design scheme. Also in the paper innovative developments applicable in the field of study are described.
