Several examples of the non-linear earthquake response analyses have been reported in the previous papers, since the principle and the procedure of the analysis by the computer-actuator on-line system were described. Here, some improvements in the system and further examples of analyses are reported. The non-linear response of a 1-bay 2-story steel frame is demonstrated, which is the initial attempt of the application of the system to a two degrees of freedom system. A frame with bolted joints is also analysed, which has the extremely complicated restoring force characteristics due to the slippages at the joints. ƒL�[ƒ��[ƒh�i‰p�j�F - ‹LŽ–‹æ•ª�F - ‹æ•ª �@�@�@ˆÏˆõ‰ï˜_•¶�W
