The purpose of this paper is to clarify the floor rigidity for the structural analysis in the case that the floor is attached only to one side of the beam. First, the ratio of the beam rigidity with floor for that without floor (the extra coefficient) was examined based on the results of finite element analysis of model composed of column, beam and floor. Next, the equation that estimated the extra coefficient was proposed based on the results of calculation in considering rigid zone proposed by authors in the end of members.
