Estudio de la influencia de imperfecciones geométricas en el comportamiento de Perfiles Tipo I (armados)

Abstract

As production is still handmade in our context, construction defects may arise during the fabrication process. Thus, this research examines the flexural impact of geometric imperfections in reinforced type I beams.

In this context, the study evaluates the behavior of type I beams subjected to flexural stresses. Therefore, “specimens” of beams with and without geometric imperfections were built. They were subjected to the point loads using a hydraulic press after an empirical laboratory process and using appropriate calculations for the Load and Resistance Factor Design (LRFD) of the concrete beam subjected to previous flexural stresses. The values obtained show a loss of up to 24.94% of resistance in the reinforced beam and the process exposed to increased temperature, causing a sinuosity in the core of the structural member.

Based on the evaluation of the results, it is concluded that the reinforced type I beams with geometric imperfections experience a significant reduction in their load capacity, thus compromising their structural resistance with values ranging from 20.46% to an alarming 24.94%, values that would seriously jeopardize a structure.
