As a prerequisite that the ceiling floor of the basements meets the standard of the certain code, the danger of the random choice of the value ‘m’ is pointed out. It may provide reference for similar engineering.Keywords: seismic design; basement with multiple building; fixed end; formula to calculate the value ‘m’
