Abstract: An earthquake resisting building is one that has been deliberately designed in such a way that the structure remains safe and suffers no appreciable damage during destructive earthquake. However, it has been seen that during past earthquakes many of the buildings were collapsed due to failure of vertical members. Therefore, it is necessary to provide vertical members strong so as to sustain the design earthquake without catastrophic failure. Capacity designing is aiming towards providing vertical members stronger compared to horizontal structural elements. A structure designed with capacity design concept does not develop any suitable failure mechanism or modes of inelastic deformation which cause the failure of the structures. In capacity design of earthquake resisting structures, elements of primary lateral load resisting system are chosen suitably and designed and detailed for energy dissipation under severe inelastic deformation.
