The purpose of this paper is to clarify the floor rigidity for the structural analysis. 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. As the result, the extra coefficient in considering the slab effective width provided in the AIJ standard was approximate to that in considering the rigid zone proposed by authors in the end of members. Next, the equation that estimated the extra coefficient was proposed based on the results of calculation in considering proposal rigid zone.
