摘要

随着时间的推移,由于不同的环境因素,木质材料可能会被拆除。由于可能发生的自然灾害或在使用期间,结构元件可能需要随着时间的推移而加强。梁是在与其轴线垂直方向上受荷载的构件。因此,它们基本上处于弯曲作用下。在对梁的抗弯性能进行研究时,我们知道材料的底面通常是断裂的。因此,近年来纤维增强聚合物(FRP)材料已被用于加固梁构件。这是一个科学事实,有必要选择frp来解决这个问题,以及它们的特性,如轻质、耐腐蚀和柔韧性,它们的应用不会破坏木材的外观。本研究旨在探讨不同性能的纤维增强高分子材料对木梁的承载力、延性、弹性模量等不同弯曲性能的影响。结果表明,经纤维增强高分子材料加固的木梁的延性和承载力比未加固的梁有显著提高。

Investigation of Wooden Beam Behaviors Reinforced with Fiber Reinforced Polymers
Wood material can be demolished over time due to different environmental factors. Structural elements may need to be strengthened over time as a result of possible natural disasters or during use. Beams are elements under load in the direction perpendicular to their axes. Therefore, they are basically under the effect of bending. When the studies on the behavior of beams against bending test are examined, it is known that the bottom surface of the material generally breaks. For this reason, fiber reinforced polymers (FRP) materials have been used in recent years to reinforce beam members. It is a scientific fact that it is necessary to prefer FRPs for the solution of this problem, as well as their properties such as lightness, corrosion and flexibility, their application without disrupting the appearance of wood.In this study, it was aimed to investigate the effect of reinforcing wooden beams with fiber reinforced polymer materials with different properties on different bending behaviors such as load bearing capacity, ductility, modulus of elasticity. It was observed that the ductility and bearing capacity of wooden beams reinforced with fiber reinforced polymer materials increased significantly compared to non-reinforced beams.
