Resumen
Con el fin de brindar seguridad y comodidad a los funcionarios y usuarios de la Municipalidad de Portoviejo cuyas instalaciones se encontraban en el edificio conocido como Palacio Municipal y se vieron afectadas por el Terremoto ocurrido en Pedernales el pasado 16 de abril de 2016, se realiza la propuesta arquitectónica con una estructura regular empleando un sistema de pórticos especiales resistentes a momentos (SMF por sus siglas en inglés) y pórticos con arriostramientos excéntrico(EBF por sus siglas en inglés) en cuyo diseño se usó la Norma Ecuatoriana de la Construcción (NEC-2015) y del American Institute of Steel Construction (AISC).
Para el diseño de columnas, vigas y arriostramientos se utilizó un acero estructural tipo A36 cuyo fy equivale a 2500kg/cm2, para la losa se asumió un hormigón con f´c=210kg/cm2.
Para realizar el análisis estructural se modelo la estructura en el software ETABS mediante el cual se determinó su respuesta ante la combinación de cargas gravitacionales y dinámicas lo que permitió realizar un adecuado diseño escogiendo los elementos estructurales capaces para resistir dichas cargas.
Finalmente se obtienen las conclusiones y recomendaciones que surgieron en el Proceso de análisis y diseño de la estructura.
In order to provide security and comfort to officials and users of the Municipality of Portoviejo whose facilities were in the building known as the Municipal Palace and were affected by the Earthquake that occurred in Pedernales on April 16, 2016, the architectural proposal with a regular structure using a system of Special Moment Frame (SMF) AND and Eccentrically Braced Frames (EBF) in whose design was used the Norma Ecuatoriana de la Construcción (NEC- 2015) and the American Institute of Steel Construction (AISC). For the design of columns, beams and braces was used a structural steel type A36 whose fy is equivalent to 2500kg / cm2, for the slab was assumed a concrete with f'c=210kg / cm2. To carry out the structural analysis, the structure was modeled in the ETABS software through which its response to the combination of gravitational and dynamic loads was determined, which allowed an adequate design to be made by choosing the structural elements capable of resisting said loads. Finally, the conclusions and recommendations that emerged in the process of structure analysis and design are obtained
