锚固装置对配筋胶合木梁受弯性能影响

Bending performance test on the different anchorage forms of reinforced glulam beams

为改善配筋胶合木梁受弯试验中试验梁两端发生局压破坏的情况,提出了一种新型的梁端锚固装置方式,通过开槽配筋胶合木梁与"L"形锚固装置开槽配筋胶合木梁的受弯性能试验,对比分析了各组试验梁的破坏形态、荷载—挠度曲线及梁端截面应变等试验数据,结果表明试验梁端局压问题得到了有效改善。

A new anchor form is proposed in order to improve the local crush of the glulam beam ends when reinforcement of the beams bending test is carried out. Comparing the slotted reinforced beams with the anchorage shape of “L” reinforced glulam beams and analyzing failure form of beams, ultimate bearing capacity, load deflection curve, beam ends ’ section strain. To conclude, the new anchor device can be used in practice.
