Honey-comb Segments were examined in the two-dimensional FEM analysis in respect of safety under the condition of Level 2 earthquake. The analysis was followed by the full scale loading test and the three dimensional static analysis. Results of these test and analysis are summarized as follows: (1) Honey-comb Segments have a sufficient strength, about 1.7 times design strength, against sectional forces developped in response to the level 2 earthquake ground motion. (2) Joints of Honey-comb

... nts indicate an excellent safety. The joint strength is considered as an ultimate strength of RC section in which the joint bolts are assumed as steel bars. An excellent seismic performance of Honey-comb Segments is verified through a series of test and analysis of this time.
