Comparison between a traditional Colombian Structural Design and the Use of Viscous-Type Energy Damping Systems (2021)

Abstract

This paper compares a traditional Colombian structural design to the same structure with viscous-type energy dampers, considering both structural behavior and construction costs. To this effect, a building was designed: first, in accordance with the Colombian Seismic-Resistant Construction Regulations (NSR-10); and then according to the recommendations of American Society of Civil Engineers with regard to damping systems. Finally, the quantities and construction costs were calculated. As a result, an unconventional structure was obtained which was more expensive than a traditionally designed building. Still, said structure had less cross-sections, stresses, and displacements. The above demonstrates that, while the initial cost of this method may be higher, the extra cost can be offset when an earthquake occurs, as the building has better earthquake resistance.
