Experimental Study on Flexural Performance of Regulated Reinforced Glulam Beam after Long-Term Loading

Due to wood creep characteristics, the failure mode, bearing capacity, stiffness, and deformation of its components are doomed be impacted by long-term loading. This paper conducted a comparative test on beams, regulated short-term beams based former loading research. The results demonstrated that glulam beam experienced tensile beam-bottom, while horizontal joint local compressive beam-end happened in reinforced prestressed beam. capacity decreased compared with beams; decline ordinary ranged from 3.2% 9.8%, 1.6% 13.2%, 2.9% 9.2%, respectively. However, restored initial value load increased 4.6–14.1%. regulation changed distribution stress thus enhanced capacity. findings this work could used as frame reference for similar engineering applications.
