What does it mean for design in Caquetá?
Municipalities in the high hazard zone. In reinforced concrete, the NSR-10 only accepts systems with special energy dissipation capacity (DES) in the high hazard zone, the most demanding detailing in the code: confinement of columns and joints, and strict drift control.
Municipalities in the intermediate hazard zone. In reinforced concrete, the intermediate hazard zone no longer allows minimum dissipation (DMI): the structure is designed with moderate (DMO) or special (DES) energy dissipation capacity, with more reinforcement detailing requirements.
Municipalities in the low hazard zone. In reinforced concrete, the NSR-10 accepts structures with minimum energy dissipation capacity (DMI) in the low hazard zone, with the simplest detailing, and for occupancy groups I and II it limits the irregularity checks to a few types (A.3.3.6).
The municipality's value is only the starting point: the soil profile sets the coefficients Fa and Fv, and the occupancy group sets the importance factor. Work out the full spectrum with the NSR-10 design spectrum, or look up another municipality in the seismic hazard tool.
