dc.descriptionA methodology for quantifying the variation of the static friction coefficient µ due to different site surface conditions, and for metallic materials with hardness ratios ρ = 0.5 – 2, is proposed. ρ is defined as the ratio between the material hardness and the A36 steel hardness. For each material, 7 coupons were considered in the site conditions “clean”, “bought”, “polished” and “corroded”. Results show if surfaces are kept as “bought”, µ may increase or decrease up to 20%, if surfaces are polished, µ may increases up to 37%, and if surfaces are corroded µ may increases up to 410% when considering corrosion rates of 90 – 670 µm/year. These increments or reductions were calculated respect to the site condition “clean”. Results also show for “clean” surfaces and for ρ ≤ 1.7, µ is dependent on ρ, for ρ > 1.7, µ is approximately constant. A model for quantifying variations of µ for the considered site surface conditions was proposed.en-US
dc.descriptionSSe propone una metodología para cuantificar variaciones del coeficiente de fricción estático µ debido a diferentes condiciones de superficie en obra para materiales metálicos con radio de dureza ρ = 0.5 – 2.9. ρ es definido como la relación entre la dureza del material y la del Acero A36. Para cada material, 7 probetas fueron consideradas en las condiciones de obra “limpia”, “comprada”, “pulida” y “corroída”. Los resultados muestran que respecto a la condición “limpia”, si las superficies se mantienen como compradas, µ puede incrementarse o reducirse hasta el 20%, si las superficies se pulen, µ puede incrementarse hasta el 37% y si las superficies se corroen µ puede incrementarse hasta el 410% para ratas de corrosión entre 90 – 670µm/año. Los resultados también muestran que para superficies limpias y para ρ ≤ 1.7, µ es dependiente de ρ y para ρ > 1.7, µ es aproximadamente constante. Un modelo que predice la variación de µ para las condiciones de superficie en obra consideradas fue propuesto.es-ES
