In the view of damage tolerant structure, while the buildings encounter a large earthquake, the beams and columns remain in elastic range, only the shear-resistant members (considered to be hysteretic dampers) may be allowed to yield. If we can predict the absorbed energies by the buildings, the damage from earthquake can be reduced to the minimum. Damage tolerant structure is consisted of two independent parts of main structure and shear-resistant members. Main structure supports the vertical loads and behaviors elastic during earthquake. Shear-resistant members are allowed to yield due to absorbing the earthquake energy. In this paper, we have proposed an optimal stiffness distribution of main structure for the damage tolerant structure to make the interstory drift angle and bending curvature be near constant throughout the height of buildings. We have also studied the influence of yield level and second stiffness as well as distribution shape of hysteretic dampers on the response subduing capacity and energy dissipation capacity of damage tolerant structure.
