What does it mean for design in Atlántico?

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.

What the code requires in Barranquilla, Soledad, Puerto Colombia, Malambo and Galapa, with each city's soil and environment, is on their structural engineering pages.
