     an offcentre bracing system that is used as a lateral- load resisting system consists basically of the non straight tension strut with an eccentricity. the mid- point is connected to the corner by the third member. in this paper, 3d finite element models using abaqus software have been prepared for one span and one story offcentre braced frames. then, a proposed mid -connection detail is compared with the commonly used one. the results indicate that the proposed mid -connection detail can improve both of the strength and ductility of offcentre braced system. furthermore, the push- over analysis show that the response modification factor and strength of braced system with suggested mid connection detail are more than those of the system with common mid connection detail.
