Metal Consumption of Frame-Bonded Steel Frames of Multi-Storey Buildings when Protecting Against Progressive Collapse
Abstract: The article considers the assessment of the metal content of a steel frame when calculating it within the framework of elastic deformations without taking into account progressive collapse, the assessment of the metal content of the frame when calculating taking into account progressive collapse, a comparison of the impact on the metal content of calculation methods for progressive collapse (static, quasi-static and dynamic formulation). The research is aimed at determining the calculation algorithm for progressive collapse, taking into account the current regulatory documents for the three calculation methods, and to assess the impact of these methods on the metal content of the supporting structures of the frame. As a result of the research, the metal consumption of the frame was estimated when calculating in an elastic formulation without taking into account progressive collapse; metal consumption when taking into account progressive collapse by three calculation methods given in regulatory documents. The scientific novelty consists in the study of the influence of calculation methods on the progressive collapse and metal consumption of multi-storey buildings, as well as the assessment of their safety and efficiency. The research performed is an important step in the field of calculating steel frames of multi-storey buildings, taking into account the progressive collapse by various methods, due to the insufficient number of publications and research in this field at the moment.
Keywords: steel frame, stress-strain state, progressive collapse (PС), metal consumption, installation stages, quasi-static method, dynamic method, coefficient of dynamism, failure time.
