The frame analysis is extensively used in designing of tunnel lining. In order to enable frame analysis of lining which involves cracking and its development, this paper proposes modeling and analytical procedures of plain concrete members. The proposed model and analytical scheme allowed us to conduct frame analysis capable of including cracking behavior, by assuming pin connection or rotating spring at nodes where a crack occurs. In addition, the effectiveness of proposed technique was verified by comparison with results of experiments using tunnel models and those of finite-element analysis based on the failure mechanics of concrete.
