IS 13920-2016 and IS 13920-1993 were used to compare the ductile design of RCC structures. The standard structural design and construction methods used in India have proved that they do not meet the basic seismic resistance criteria. One of the key issues that needs to be addressed is the use of ductile design and detailing methods in building structures. In general, the ductility of reinforced concrete structures is a concerning issue. To prevent seismic damage and life-threatening collapse, certain design considerations and reinforcing detailing can be applied in specific crucial spots of the structure. For ductile detailing and design, an earthquake-resistant construction should follow IS 456 and IS 13920. When RCC framed constructions are given ductile detailing, they become moment-resisting frames. In the revised ductile detailing code, the structural design and detailing clauses have been updated, structures designed in the past using the old code lacked in design and detailing clauses for a high seismic force as compared to buildings analyzed under the revised IS 13920 codes. A confinement zone in a structural member is a place where additional ductility is required, which can be achieved by reducing transverse reinforcement spacing. Greater ductility is necessary during an earthquake or any other reason for transverse deformation of the member. The concrete of the RC member experiences the maximum nonlinearity in its stress-strain response during an earthquake, hence the increased transverse reinforcement benefits in seismic energy dissipation. Common examples of confinement zones include column ends, beam ends, beam-column couplings, and other critical locations. As a result, additional limiting reinforcement is provided at these locations, usually in the form of closely placed ties. If a significant amount of transverse reinforcement is required to achieve the shear strength requirements of beams and columns, such transverse reinforcement must be provided as per revised code, and special confining reinforcement is not required, according to the modified IS 13920.
