Structural performance of hybrid mengkulang glulam concrete beam / Shuhada Mohd Yusoff

Engineered wood products, such as glued laminated timber (glulam), are designed to decrease the weaknesses of natural wood, such as knots and non-uniform strength, and so increase stiffness and weight carrying capability. One way for increasing the load carrying capacity and performance of glulam st...

Both HMGCs failed due to MG layers splits in the tension zone on weaker zone (finger-joint area) and concrete cracks in the compression zone.
