Este proyecto pretende aportarle a presentes y futuros dise?adores estructurales una idea concisa de la posible diferencia econ?mica; entre dise?os que involucren dos de las tres capacidades de disipaci?n de energ?a que contempla la normatividad sismo resistente colombiana NSR-10, ?DMO vs DES?. Para esto se plante? el c?lculo y dise?o de tres estructuras sim?tricas de cuatro, siete y diez niveles, sujet?ndolas a condiciones espec?ficas; tales como un perfil de suelo tipo D, nivel de sismicidad intermedia para la ciudad de Ibagu?, y sistema estructural aporticado aplicando a su vez los requisitos para DMO y DES exigidos en la NSR-10, con objeto de estimar los costos; y obtener soportes sometidos a juicios comparativos, para determinar con que capacidad de disipaci?n de energ?a ser? econ?micamente conveniente dise?ar para DMO o DES.This project aims to provide present and future structural designers with a concise idea of the possible economic difference; between designs that involve two of the three energy dissipation capabilities contemplated by the Colombian earthquake resistant standard NSR-10, "DMO vs DES". For this purpose, the calculation and design of three symmetrical structures of four, seven and ten levels were proposed, subjecting them to specific conditions; such as a soil profile type D, intermediate seismicity level for the city of Ibague, and structural system aporticado applying in turn the requirements for DMO and DES demanded in the NSR-10, in order to estimate costs; and to obtain supports submitted to comparative judgments, to determine with which capacity of energy dissipation it will be economically convenient to design for DMO or DES.
