Moment Curvature Analysis of RC Column as per IS 456:2000

Pramodini Naik Gaonkar and Dr. Satish A. Annigeri


Abstract:

The current seismic design practice stops at demand estimation, analysis and design and consequently cannot guarantee that the designed structure meets the objectives set at the start. Performance based design (PBD), which involves performance evaluation and redesign if necessary, is a better approach to structural design. Most inelastic analysis methods assign point plasticity at section locations where plastic deformations are most likely to occur. Such programs require the force-deformation relation of such plastic hinges to be input. Deformation capacity of reinforced concrete columns is of paramount importance in PBD. The deformation capacity of a column can be expressed in terms of i) curvature ductility ii) displacement ductility and iii) drift. The ductility of reinforced concrete member can be determined from the moment curvature relationship [3,4,5,6]. The present paper describes the detailed procedure for computing the moment curvature relationship for RC columns as per IS 456:2000, for given column cross section and axial load and development of a program using VBA in Microsoft Excel for computing moment curvature values.
