چکیده:

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 -poit 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 coomonly used one the results imdicate that the proposed mid-connection detail can improve both of the strength and ductility of offcentre braced system .
