新疆杨是新疆特有并且在新疆应用广泛的杨木梁品种,目前,针对新疆杨木梁的研究较少。通过抗弯试验研究新疆杨木梁的抗弯性能,对新疆杨木梁的基本力学性能、含水率、顺纹抗拉强度、顺纹抗压强度和横纹抗压强度等进行测定。并通过5根矩形截面新疆杨木梁的抗弯试验,验证平截面假定,得出新疆杨木梁的破坏特征、极限荷载以及荷载与应变、荷载与挠度之间关系。
Xinjiang poplar is endemic to Xinjiang and poplar varieties widely used in Xinjiang, at present, less research on poplar for Xinjiang. The bending properties of Xinjiang poplar beam were studied by bending test, and the basic mechanical properties, moisture content, parallel grain tensile strength, parallel grain compressive strength and transverse grain compressive strength of poplar beam in Xinjiang were measured. Through the bending test of five poplar beams with rectangular cross-section in Xinjiang, the plane cross-section assumption was verified, and the failure characteristics, ultimate load and the relationship between load and strain, load and deflection of Xinjiang poplar beam were obtained.
