Inelastic seismic response of a six-story three bay diamondbraced frame and a K-braced frame due to first ten seconds of the 1967 Koyna earthquake is studied in this paper. The effect of using moment-resistant connections or pin-connections with girders in the outer unbraced bays and,hence the interaction between the outer bays and inner bay is considered. The hysteresis behaviour of steel bracing members was represented by a buckling model which is based It is concluded that interaction results on experimental results. in lesser ductility requirement in girders. It is also noticed that K-braced frames are better than diamond braced frames. ƒL�[ƒ��[ƒh�i‰p�j�F - ‹LŽ–‹æ•ª�F - ‹æ•ª �@�@�@ˆÏˆõ‰ï˜_•¶�W
