Structural engineering in Soledad

What does the NSR-10 require to build in Soledad?

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).

If the geotechnical study gives a type D profile, the Soledad design spectrum for a residential or office building (occupancy group I) has a plateau of Sa = 0.40 g up to TC = 0.72 s, and TL = 5.76 s. With another soil or another use the values change: work them out with the design spectrum.

What should you watch for in Soledad's soil?

Soledad lies on the banks of the Magdalena River. On lots near the river, the geotechnical study must establish whether there are layers of soft clay or loose, saturated sands: three meters or more of soft clay make a type E profile, and soils that can liquefy during an earthquake are type F, which requires a site-specific study (A.2.4.5 and A.2.10). With a type E profile, the plateau of the spectrum is more than one and a half times that of a type D profile in the same municipality.

And the water?

Near the river the water table is usually high. The foundation and basements must be designed for it: uplift, waterproofing and excavation procedures that the geotechnical study must recommend to the contractor (A.1.3.2).

When does Law 1796 require review and technical supervision in Soledad?

The rule is the same throughout the country: when the lot allows more than 2,000 m² to be built, whatever the use, Law 1796 of 2016 requires an independent review of the structural designs before the permit and independent technical supervision during construction. Buildings in occupancy groups III and IV, such as schools and hospitals, require technical supervision whatever the area (A.1.3.9.1). Check your case with the Law 1796 assistant.
