2. Methodology

Two important elements of seismic performance evaluation of buildings are demand and capacity spectra. Demand spectrum is the representation of the severity of the ground motion while capacity spectrum depicts the ability of the structure to withstand forces of specific nature. Demand spectrum has to be modified to account for lengthening of the period or increase in the damping of the structure. Proposed methodology adopts capacity spectrum method [4,19,20] to generate the demand spectrum as the method has provisions to accommodate the modifications. Fig. 1 gives the overall structure of the proposed methodology, individual steps and the sequence in which these are to be executed.
Considerable knowledge and experience exist in literature for the generation of capacity spectrum of a structure by adequately taking care of nonlinear behaviour of both concrete and reinforcing steel. State-of-the-art lies in the availability of ready-to-use software with wide range of options for modelling almost all cases that are likely to be encountered in practice. On the other hand, generation of demand spectrum by properly accounting for the nonlinear behaviour of soil at site is a challenging task. Successful generation of demand spectrum requires input on various aspects like proximity to and nature of the source of earthquake, path effects of seismic waves and local soil conditions. Due to its nature, a comprehensive methodology that can address all the important issues is essential for generation of demand spectrum.
