Capacity Based Earthquake Resistant Design of Multi-Storied R.C. Building: A Review

Abstract

Presented in this paper is an updated literature review of the Capacity-based Seismic design (CBSD) method.
Concept of CBSD is the spreading of inelastic deformation demands in a structure in such a way so that the formation of
plastic hinges takes place at predetermined positions and sequences. It is an art of avoiding failure of structure in brittle
mode.Shear failure is brittle mode of failure, hence shear capacity of all components capacity based design are made
higher than their flexural capacities so as to avoid shear failure. Therefore, it is better to make beams to be the ductile
weak links than columns.In the capacity design of structures for earthquake resistance, distinct elements of the primary
lateral force resisting system are chosen and suitably designed and detailed for energy dissipation under severe imposed
deformations. The critical regions of these members, often termed as plastic hinges, are detailed for inelastic flexural
action.
