Resumen
En el trabajo se presenta la elaboración de un manual de usuario para la interfaz Open Application
Programming Interface (OAPI) SAP2000 – MatLab para la solución de problemas de optimización
de un conjunto de estructuras espaciales bajo las condiciones actuales de costo en Cuba, para
las cargas predominantes en la región occidental de nuestro país. En el trabajo se incluyen
aspectos usualmente ignorados en la modelación y el análisis estructural, como la influencia de
la fisuración en la rigidez de elementos como vigas y columnas y la inclusión de un análisis de
Segundo Orden. Por cuanto se busca la mayor economía en el diseño, se utiliza como función
objetivo el costo mínimo, se modela matemáticamente el problema definiendo: variables,
restricciones.
Lo realmente novedoso del trabajo es la organización de los comandos que se utilizan en la
solución de un problema de optimización a través de la interfaz SAP2000-MatLab (OAPI) en una
estructura y un manual de usuario que sea de más fácil manejo para otros usuarios en aras de
lograr que adapten su caso de estudio más rápidamente, a la formulación del problema de
optimización requerida, con las herramientas mencionadas.
Finalmente, se aplica la nueva estructura formulada a la solución de un problema de optimización
de estructuras espaciales, y se extraen conclusiones y recomendaciones de diseño, válidas para
los proyectistas en edificaciones cuyo esquema de resistencia frente a cargas horizontales es
aporticado.
The paper presents the development of a user manual for the Open Application Programming Interface (OAPI) SAP2000 - MatLab for solving optimization problems of a set of spatial structures under the current cost conditions in Cuba, for the predominant loads in the western region of our country. The work includes aspects usually ignored in the modeling and structural analysis, such as the influence of cracking on the stiffness of elements as beams and columns and the inclusion of a Second Order Analysis. As the largest economy in the design is sought, the minimum cost is used as the objective function, the problem is mathematically modelled by defining: variables and constraints. The really new thing about the work is the organization of the commands that are used in the solution of an optimization problem through the SAP2000-MatLab interfaz (OAPI) in a structure and a user manual that is easier to handle by other users in order to adapt their case studies more quickly to the formulation of the required optimization problem, with the mentioned tools. Finally, we apply the new formulated structure to the solution of an optimization problem of spatial structures, and draw conclusions and design recommendations valid for designers in buildings whose the main resisting system against horizontal loads is framed.
