The purpose of this paper is to clarify the rigid zone lengths for reinforced concrete members. The rigid zone lengths were calculated from the results of finite element analysis of beam-column members. The equations to estimate the rigid zone lengths were derived to utilize those rigid zone lengths. The estimated rigid zone lengths were applied to the 3-spans 9-stories reinforced concrete frame, and those frames were analyzed by stiffness method. The results of the analysis were very much in agreement with the results of finite element analysis of those frames.
