Design of a spreadsheet for ConXtech ConXL 400 connection check to be used in IPE 450, 500, 550 and 600 profile beams to tubular column filled with concrete

Abstract

Design a Spreadsheet for connection checking ConXtech ConXL 400, to be used in IPE 450, 500, 550 and 600 profile beams, to tubular column filled in concrete, due to the large number of types of connections that can be found for uniting the components of a structure and the lack of technical knowledge of some manufacturers who, due to their experience in companies, have decided to undertake and become independent, creating a metal structure manufacturing and assembly company, not having adequate knowledge at the time of establishing a connection between two elements can considerably affect the seismic behavior of the structure, generating a specific fault which could destabilize the elements causing them to fail and collapse causing the collapse of the building. The earthquakes that occurred in the cities of Northridge (USA) (1994) Magnitude 6.7 Mw and in Kobe (Japan) (1995) Magnitude 6.9 Mw., Events in which several existing problems in the design of earthquake-resistant structures were evidenced, and In buildings where the structural system was made up of moment-resistant frames (PRM), deficiencies were evidenced in the connections used at this time, due to these events the development of metal connections, within the construction sector was doomed to a significant advance in research. This spreadsheet was formulated in such a way as to perform a check on each type of metal profile proposed within the problem statement, with the eleven (11) steps defined by the AISC 358-16 Standard (AISC-American Institute of Steel Construction), for the use of the ConXtech ConXL 400 connection.
