Resumen
Este proyecto se ha desarrollado con el fin de mostrar el análisis y diseño de la estructura de un galpón industrial de 50 m de longitud, en el cual actúan de manera simultánea dos puentes grúa de 25 ton de capacidad. El galpón se encuentra ubicado en la parroquia Pascuales, perteneciente a la Ciudad de Guayaquil provincia del Guayas, y está destinado únicamente para fines académicos.
Inicialmente se procedió a obtener las dimensiones y las acciones máximas que provoca el puente grúa, las cuales van en función de la luz y de la carga que se manejara dentro del galpón industrial, ya con estos datos se obtuvo la sección de viga carril capaz de soportar todas las cargas actuantes. Una vez obtenidas las reacciones máximas en los apoyos de la viga carril, se diseñó manualmente la ménsula.
Para el pre-dimensionamiento de los elementos estructurales del galpón industrial, los cuales estarán compuestos de acero A572-G50, se evaluaron las cargas, muerta, viva, de viento y sísmicas propuestas por la NEC-15. Luego de haber estimado las secciones de columna, dintel, correas, se procedió a modelar la estructura en SAP 2000 con las cargas respectivas y se comprobó que las secciones cumplan con los criterios de diseño propuestos por el AISC-360 y la NEC-15.
En el diseño la placa base, se optó por incluir rigidizadores en la dirección más desfavorable para disminuir su espesor, y por último se diseñó la cimentación compuesta por zapatas aisladas de sección cuadrada que cumplen con las verificaciones necesarias para su correcto diseño.
This project has been developed with the purpose of showing the analysis and design of the structure of an industrial warehouse of 50 m in length, in which two bridges-crane of 25 ton of capacity act simultaneously. The warehouse is located in the Pascuales parish, belonging to the City of Guayaquil, province of Guayas, and is intended solely for academic purposes. Initially we proceeded to obtain the dimensions and maximum actions caused by the bridge-crane, which are depending on the span and the load that would be handled inside the industrial warehouse, and with this data the section of beam-rail will be capable of support all the acting loads. Once the maximum reactions were obtained in the supports of beam-rail and the corbel was manually designed. For the pre-dimensioning of the structural elements of the industrial warehouse, which will be composed of A572-G50 steel, the dead, live, wind and seismic loads proposed by the NEC-15 were evaluated. After having estimated the sections of column, lintel, rib-beams, we proceeded to model the structure in SAP 2000 with the respective loads and it was verified that the sections meet the design criteria proposed by the AISC-360 and the NEC-15. In the design of the base plate, it was decided to include stiffeners in the most unfavorable direction to reduce their thickness, and lastly, the foundation was designed with an isolated square section footing that comply with the necessary verifications for their correct design.
