Seismic Performance Evaluation of Moderately Ductile RC Frame Structure Fe Model With Perform-3d


Abstract eng:
The principles for seismic assessment of buildings have shifted from strength-based to performance-based evaluation. Performance-based assessment involves evaluation of structures for pre-determined performance objectives. The structures are analyzed under different earthquake records with different intensities through response history analysis. Inelastic response history analysis requires analytical modelling of buildings and computer software that captures structural performance in the non-linear range of deformations. The objective of this paper is to present analytical modelling techniques for reinforced concrete (RC) frame structures, suitable for use with PERFORM-3D software. A detailed discussion of the effects of modelling parameters on structural response is presented. The parameters of moment-rotation envelope used for hysteretic modelling of members are described. The features of hysteretic modelling, including stiffness degradation as controlled by the “energy degradation factor” and strength decay are presented. An analytical model of a 5storey moderately ductile reinforced concrete frame building, designed based on the current Canadian practice, was generated for use with PERFORM-3D software. The structure was analyzed to assess global and component level responses by monitoring inter-storey drift ratios, formation and sequence of plastic hinging, and load-displacement hysteretic relationships. The suitability of the analytical model developed for PERFORM-3D was verified against SAP2000 and SeismoStruct software. The paper presents the construction of the analytical model, model validation, hysteretic modelling, and the results of dynamic analyses. Structural performance is presented at different limit states employed as performance objectives.
