The result comparison between the simulation and experiment.

Parameter	Yield load (kN)	Yield displacement (mm)	Peak load (kN)	Peak displacement (mm)	Ultimate load (kN)	Limit displacement (mm)	Displacement ductility coefficient
Test result	25.32	3.78	37.75	35.17	33.68	49.15	13.00
Simulation result	27.12	4.04	36.33	33.28	32.16	48.38	11.98
Error (%)	7.11	6.88	3.76	5.37	4.72	1.57	7.84

The limit displacement: since the skeleton curve does not decrease to 85% of the maximum bearing capacity, the displacement corresponding to 90% of the maximum bearing capacity is taken as the ultimate displacement in this paper.
