| description | The safety analysis of the outermost column of the 8 m high building stylobate was performed under eccentric compression. The bending moments act in two main planes. Modeling of the emergency based on physical and geometrical nonlinear calculation in dynamic statement is proposed. The dynamic overload is modeled simultaneously by longitudinal force and bending moments. It is assumed that such an emergency impact is caused by an impacting body falling from a certain height onto the deformable slab in the vicinity of the slab-column connection zone. An impulse load modeled the load, the magnitude and duration of which were approximated based on the conservation of momentum law. As a result, an area of structural strength, limited by the boundary surface under dynamic loads, was plotted. The mechanical safety consisted in assessing the risk of material damage associated with the collapse of a part of the building structure when the column collapsed. |
