This involves the estimation of the structural strength and available capacities and the comparison with the deformation demands at desired performance levels. Seismic evaluation of existing structures and of the proposed design for new structures can be done based on Non-linear Static Procedure popularly known as Pushover Analysis (PoA). The ‘Iterative Procedure (Optional)’ mentioned in Eurocode 8 (EC8) has been developed to an EC8 based Capacity Spectrum Method (CSM) procedure and is investigated here. Since commercial packages, including SAP2000 which was used for this investigation, has no facility for conducting an EC8 based CSM, a method was developed, and the procedure is programmed in VB-Script and embedded in MS-Excel. The paper also attempts to investigate the Consecutive Modal Pushover (CMP) analysis, using the EC8 based CSM procedure developed. Although the procedure for CMP in its original paper was a Displacement Coefficient Method based one, a trial-and-error procedure is being followed here for adapting the procedure for a CSM based approach. The study includes modeling of a typical realistic building and determination of Performance Point for both conventional single mode PoA as well as for CMP, both using VB-Script program developed for the EC8 based CSM procedure. The verification of results is done by comparing results with the Non-linear Time History analysis. The procedure developed for the EC8 based CSM – the method for plotting the Locus of the Performance Point and consequent determination of the Performance Point – is also explained in detail, step-by-step.
