Diseño y construccion de cubierta metalica 400 m² fase i comparando el metodo del asd (diseño por tensiones admisibles) y el metodo lrfd (diseño por factores de carga y resistencia), de la nueva biblioteca central de la Universidad Tecnica de Manabi

Abstract

This thesis group has chosen intervention scenario for implementing the project, the Technical University of Manabí, located in the canton of the Parish Portoviejo March 12 "Avenue street Urbina and Che Guevara". Among the branches of engineering are many tools to analyze and design magnificent structures ranging from a small screw to the components of a building, such as formulas and procedure in the current era is synthesized in software that offer great variety, speed and reliability. We as students framed within a theoretical field and eager to ensure that the comparison of the method ASD (Allowable Stress Design) and LRFD (Load Factor Design and Resistance) with different forms of analysis and design give us results that meet the requirements of the structure to be built. To prepare the analysis of the armor was split based on the principle of static. Through this concept has searched the technology available for processing. The analysis has made it through the SAP 2000 program that has met all our expectations. For the preparation of the various designs we worked with the regulations imposed by the Ecuadorian Code NEC 2011, and American codes for different types of profiles properties and used as is the AISI standard "American Institute of Iron and Steel". It turned out very satisfying to see the comparison of these ASD and LRFD methods yield similar values us as despite their different combinations the results are very reliable. It is considered to have met the proposed objectives and delivered to the Technical University of Manabí to serve as a tool in the quality training professionals.
