Finite element modeling of stress-strain state of girderless floor construction caused by progressive collapse

Purpose: Finite element modeling (FEM) of the stress-strain state of the five-storey frame building with girderless floors and the basement caused by progressive collapse.Methodology: FEM is performed in the MicroFe software with the removal of the medium column  in  the  basement  using  the  limit  equilibrium  theory.  Development  of  the  three-dimensional model on a rigid base.Research findings: It is shown that progressive collapse of girderless floors is impossible after the removal of the medium column in the basement of the experimental building.
