Comparison of test values and calculated values of eccentric compression columns.

Specimen number	Test value (kN)	Calculated value (kN)	Difference value (kN)	Relative error
Z-5	381.56	378.21	−3.35	−0.88%	26.60%
Z-6	457.38	478.76	21.38	4.67%	42.03%
Z-7	682.40	664.93	−17.47	−2.56%	22.70%
Z-8	794.78	815.75	20.97	2.64%	37.0%

Note: P_u1 represents the test results of specimens;. P_u2 represents the theoretical calculation results of specimens; P_c represents the bearing capacity of wood obtained by theoretical calculation.
