Generally speaking, if the floor is qualified concrete floor, and appropriate vibration mitigation measures are taken when using barbells, the impact of barbells on the floor is very small, and it will not cause damage or collapse of the floor.
However, if the ground is weak cement or tile ground, or there are no measures to slow down the vibration when using barbells, the barbells will have a great impact on the ground, which will cause cracks, fragmentation, vibration and other problems, and even affect the residents upstairs and downstairs.
