摘要
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 is widely used in Xinjiang,but there are less researches on the Xinjiang Poplar.It was studied the flexural behavior of Xinjiang Poplar beam,and the basic mechanical properties,moisture content,tensile strength,compressive strength perpendicular to the grain of Xinjiang Poplar were measured.The bending tests of 5 Xinjiang Poplar beams of rectangular cross-section were done to verify the plane section assumption,and the Xinjiang Poplar timber beam＇s relationships among failure characteristics,ultimate load,load-strain,load-deflection etc were obtained.
