摘　　要：正交胶合木(CLT)在木结构建筑中应用越来越广泛,特别是在中高层建筑物中。CLT作为楼盖构件使用时,承受柱或墙体施加的垂直荷载,因此CLT产品的设计及应用需要其横纹承压弹性模量和强度方面的参数;改善CLT横纹承压性能,也可以提高整体结构强度和建筑安全系数。文中主要介绍目前CLT横纹承压性能测试方法,总结CLT横纹承压性能影响因素方面的研究进展,以期为国内CLT研究提供参考。Cross-laminated timber(CLT)has been widely used in wood frame structures,especially in medium and high-rise buildings.When it is used as a floor component,CLT bears the vertical load imposed by columns or walls.Therefore,the parameters of modulus of elasticity and strength in compression perpendicular to grain are needed for the design and application of CLT products.And the overall structural strength and the building safety coefficient can be improved with the improved properties of CLT in compression perpendicular to grain.This paper mainly introduces the current test method of CLT in compression perpendicular to grain,and summarizes the research progress of the influence factors of CLT in compression perpendicular to grain,to provide references for domestic CLT research.
