Creación de una herramienta de chequeo de conexiones precalificadas con verificación de la norma vigente

Abstract

The present work is oriented to generate a tool for checking connections in metal constructions, pre-qualified connections are a fundamental part in the performance of metal structures when they support cyclical horizontal forces because they are the ones that ensure adequate dissipation of energy produced by movements that cause horizontal forces. For the generation of the templates were taken into account the structures of frames resistant to moments IMF and SMF, focused on End Plate connections (end plate) of four bolts with stiffener and without stiffener. The methodology for the creation of the Excel template for free access and easy handling for the pre-qualified connection type BCF or End-Plate, was carried out step by step according to the requirements established in the ANSI / AISC 358-16 standard. The results of the template were compared with the results of the RAM-Conection program, finding similar results that validate the calculations made in the Excel template. Additionally the template shows the formulas used for the calculations of the different limit states that must be taken into account in the calculation of the connection and shows some tips that we consider key for the engineer that makes the designs.
