"The research in this paper focuses on issues related to determining the maximum horizontal inertial load transmitted from the bridge crane to the supporting structure of the building in the event of a sudden stop of the crane. The article begins by examining the generally accepted simplified relationships regulated in design standards, which are most often used by engineers to determine the maximum horizontal inertial loads from a bridge crane to the supporting structure of a building. For a more accurate determination of the horizontal inertial loads, a mechano-mathematical model was developed in this paper to study the dynamic behavior of the crane supporting structure and the suspended load in the event of a sudden stop of the crane. Example structures of bridge cranes with three different possible nominal speeds of movement of the crane were examined. For each of the considered examples, a numerical solution of the differential equations was performed, and results were obtained for the transmitted horizontal inertial load from the bridge cranes to the supporting structure of the building in the event of a sudden stop of the crane. Finally, a comparison of the maximum horizontal inertia force during braking obtained by the differential equations with the results obtained using the simplified dependencies from the design standards is made. The conclusions drawn may be useful for clarifying the cases when the realized horizontal inertia loads in the event of a sudden stop of the crane may be greater than those obtained using the methodology prescribed in the design standards."
