    Evaluation of the stress-strain state of the metal frame structures of a high-rise building
    (National Aviation University, 2020-12) Rakovych, Maksym; Ракович, Максим Анатолійович
    In the thesis the estimation of the stress-strain state of metal frame constructions of a high-rise building is carried out. The building developed in this work will be used for offices. Static and dynamic calculation of the frame of buildings, and, consequently, calculations of the main structural elements of the building, such as: metal column, pile foundation with a slab, the main metal beam. Calculated the bearing capacity of the elements in case of emergencies, such as progressive collapse. Progressive collapse - a phenomenon in which there is a sequential, chain destruction of load-bearing structures, resulting in the destruction of the entire structure or part thereof due to the primary isolated destruction As a result of the expected initial local destruction, which leads to a change in the structural system, create a structure to protect buildings and structures from progressive collapse, which is performed in an emergency design situation. To do this, calculate the indicators of the ultimate state, which is provided by the bearing capacity, deformation and stability of the deformation form of the structural system of the building and structure as separate elements of joints, except remote, in case of local destruction and as a whole. During the entire service life, the structure can be affected by extreme load conditions that significantly exceed the usual design assumptions, which can lead to catastrophic consequences. The influence of numerical rigidity of knots on bearing capacity of steel elements of a high-rise building in case of emergency was investigated.
