Solución estructural modular para naves industriales de gran luz y montaje por fases

Abstract

This graduation project addresses the design of a structural solution for a large-span industrial warehouse, justified by the need to expand infrastructure within an environment with severe operational constraints that prevent conventional construction. The objective is to conceive a modular system that allows for phased assembly without affecting existing operations or pre-existing infrastructure. For its development, a systematic design methodology was employed, where a hybrid alternative of reinforced profiles was selected through a multi-criteria decision matrix. This concept was dimensioned by applying principles of mechanics of materials and validated using a three-dimensional computational model through finite element analysis (FEA) under the AISC 360-16 and NEC standards. The simulation yielded as main results a minimum safety factor of 1.8 and a maximum deflection of 28 mm (L/750), values that confirmed the system's integrity. In conclusion, the proposed design constitutes a robust, functional, and documented engineering solution that meets all technical and operational requirements, demonstrating the viability of phased construction in complex industrial contexts.
