Based on a concrete building removal project, the rolling friction coefficient and the elastic resilience behavior of its rollers were investigated. A new technology of vertical isolation vibration used in building removal was proposed. The principle of this technology was stated, and its effect of isolation vibration was analyzed through computer simulation. The natural vibration periods of the removed building before and after its stiffness increment were calculated, and then the period of building removal was determined in the engineering application. These results can be used to safely and reliably remove buildings with large space and complex structure, and have been applied to the building removal project.
