摘　　要：木质工字梁是一种资源高效利用型现代木质建筑材料,梯形槽胶连接是预制木质工字梁翼缘/腹板最常用的接口方式。对其力学性能的研究表明:接口角角度β和接口槽深i是影响接口力学性能和工字梁整体承载能力最为关键的技术参数。Wood I-beam is a kind of modern wood building material featuring efficient use of resources,and trapezoidal groove glue connection is the most common interface mode for prefabricated wood I-beam wing edge/web interfaces. The study on its mechanical properties shows that the interface angleβand interface groove depthiare the most crucial technical parameters influencing interface mechanical properties and I-beam carrying capacity.
