主　　题：Cross-laminated timber out-of-plane shear properties testing methods failure modes 

摘      要：The out-of-plane shear properties of cross-laminated timber(CLT)substantially influence the overall mechanical properties of *** testing methods and theories related to these properties have recently been *** effects of the number of layers(three and five layers)and testing method(short-span three-and four-point bending tests)on the out-of-plane shear properties of CLT were *** out-of-plane shear strength values were calculated based on different theories for *** failure mode in the short-span four-point bending(FPB)method was mainly the rolling shear(RS)failure in the cross layers,indicating that the FPB method was appropriate to evaluate the RS strength of *** out-of-plane shear capacity obtained using the three-point bending(TPB)method was higher than that tested by the FPB *** testing methods significantly influenced the out-of-plane shear capacity of the three-layer specimens but not that of the five-layer *** an increase in the number of layers,the out-of-plane shear strength of the specimens decreased by 24%.A linear correlation was found among the shear strength values obtained from different theories.
