  • On the development of structural schemes for skeletons of high-rise monolithic reinforced concrete buildings

    This article raises the issue of designing high-rise monolithic reinforced concrete buildings. Possible applications of the main parts of the building frame to create the optimal structural scheme in accordance with the requirements for providing the building with stiffness, stability, resistance to external forces and resistance to deformations are presented. It also offers a modern method of structural analysis, which allows to ensure durability and all necessary conditions for the safe operation of the building

    Keywords: structural scheme, rigidity, stability, reliability, frame, load-bearing element, structural system, "flexible layout", wall systems, finite element method

  • 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 practice of using shell constructive system in the construction of tall buildings

    In this review article high-rise construction is considered, factors affecting the choice of a constructive system of a building are given. The shell (box-shaped) structural system is described in detail. The advantages and disadvantages of this structural system are listed.

    Keywords: high-rise building, structural system (CS), shell (box-shaped) system, horizontal load, stiffness, stability, bezreskosnaya grille, diagonal grille, column, strapping beam, diagonal connection
