Abstract:

In this paper, we discusses the manufacturing, analysis, and testing of two glulam beam designers:(1) Southern pine bulb, and (2) yellow-poplar reinforced with pultruded fiber-reinforced plastic (FRP) composite. Six 40-ft long glulam-bulb and twelve 20-ft long glulam-FRP beams were commercially manufactured and tested to failure in bending. The linear response evaluation includes measurement and prediction of strains and displacements. The failure of the beams are predicted following ASTM D3737.
