摘要

•Explicit formulae are established to compute the maximum displacement of floor.•The effects of impactor mass, impact height, floor span, slab thickness, rebar diameter, and beam depth are studied.•Coefficient of restitution in impact is considered.•Practical recommendations for the maximum displacement of floor are proposed.
