Análisis comparativo entre las uniones soldadas y apernadas para la edificación “La Fabril” en el cantón Manta

Abstract

In this project, two types of prequalified connections, 4ES and 8ES, described in chapter 6 of AISC 358-2022, are developed and analyzed as the first alternative. Additionally, the welded connection WUF-W is designed, according to chapter 8 of the same standard, as the second alternative. The work begins with a theoretical analysis of each type of connection, detailing step by step the mathematical procedure required to calculate the essential parameters. In relation to the welding aspects between the connection elements, technical references, and recommendations from the AISC 358-2022 and AWS D1 standards are incorporated. The practical methodology, presented in the third chapter, includes the modeling of the structure in a calculation software, followed by the verification of the strength and stiffness of beams and columns in all moment-connected frames. Subsequently, the specific calculations for the two connection design alternatives are focused on. The characteristics of the beams to be connected are specified, considering the dimensions of their cross sections, such as height and width. Calculations are performed following the procedures and verifications established in AISC 360-22. As a result, detailed designs of the connections are presented, including all parameters, dimensions, and specifications necessary for their correct implementation in both alternatives.
