In this article, the impact of vibration loads on load-bearing floor structures is investigated. These loads were caused by machinery operation process in the five-storey factory building. Within this case study, examination of the structure was performed to measure the real vibration level and evaluate the damages to the structure. The analysis of the results has shown overloading the structures by machinery vibrations. The paper reflects a reasonable approach to rapid estimating of amplitude limits for floor structures avoiding complex calculations. Measured experimental values of amplitudes and precipitations under various productivity levels are given in this study. Theoretical and experimental data comparison appeared slabs subjected to vibration overloading and dynamic deflections. Some control points have shown significant exceeding amplitude limitations. Provided investigations of structure damages, in this case, also confirmed critical areas. It was revealed that incorrect machinery service entailed excessive vibration loads on the structures. Subsequent reinforcement works were provided to eliminate the cracks in structures.
