The aim of this study is to get the spatial average stress- average strain relationships of both reinforcing bars and cracked concrete in RC members based on the local bond characteristics between concrete and reinforcing bars and tension-fracture of plain concrete. The computations are based upon the versatile local bond stress-slip-strain model. The local stress and strain profiles of both reinforcing bars and concrete between two adjacent cracks are explicitly evaluated with the softening bridging stress at individual cracks. From these profiles, the spatial average constitutive model in tension is derived. The computation is also capable of predicting the average crack spacing.
