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。
In order to improve the situation of local pressure failure at both ends of the test beam in the bending test of the glued-laminated wooden beam, a new type of beam-end anchorage device is proposed. The slotted glued- The flexural properties of the glued timber beams with slotted reinforcement were tested. The failure modes, load-deflection curve and strain at the beam end of each group were compared and analyzed. The results show that the pressure on the beams at the beam end has been effectively improved .
