La madera laminada encolada (GLULAM) se ha utilizado ampliamente en la construcción debido a su alta resistencia y versatilidad. Sin embargo, es susceptible a fallas frágiles a flexión, lo que hace necesarios refuerzos estructurales para mejorar su desempeño. Este trabajo presenta una revisión bibliográfica de los métodos de refuerzo de vigas de GLULAM, con énfasis en el uso de polímeros reforzados con fibras (FRP). Se abordan las características del GLULAM, los principales materiales de refuerzo, las metodologías de inserción de barras y la modelación numérica mediante el Método de los Elementos Finitos (MEF). Los estudios revisados muestran que el refuerzo con FRP mejora la resistencia y la rigidez de las vigas, aunque aspectos como la adherencia y el comportamiento frente al fuego aún requieren investigaciones adicionales. Esta revisión identifica vacíos en la literatura y propone enfoques para optimizar los refuerzos mediante la combinación de métodos experimentales y numéricos.
