Response of 5- and l0-story R/C space frame structures subjected to simulta -neous two horizontal earthquake motions was analyzed. In the analysis, column bi-axial flexural interaction was considered, and column flexural strength was selected as a main parameter. The major findings from the study are : �¡ as the column strength increases, column ductility decreases and the structure tends to produce the total yield mechanism, and �¡ the column overstrength ratios requited to achieve the total yield mechanism for the 5-story structure are larger than the values prescribed in the Design Guidelines for R/C Buildings, while those for the l0-story structure are smaller. ƒL�[ƒ��[ƒh�i‰p�j�F - ‹LŽ–‹æ•ª�F - ‹æ•ª �@�@�@ˆÏˆõ‰ï˜_•¶�W
