Experimental Study and Numerical Simulation Analysis on Reinforcement of Mortise-Tenon Joints with Flat Steel Strips

Table 10

Comparison of FEM and experimental results.

Mortise-tenon type	Reinforcement method	Total energy of FEM	Total energy of experimental	Total energy ratio (%)	Ultimate load capacity of FEM	Ultimate load capacity of experimental	Ultimate load capacity ratio (%)
Tou mortise-tenon joints	Reinforced	3.75	5.19	72.25	2.59	3.59	72.14
	Unreinforced	5.46	5.5004	99.27	4.32	4.08	105.88
Ban mortise-tenon joints	Reinforced	1.68	2.1958	76.51	0.71	0.6	118.33
	Unreinforced	8.87	4.0293	220.14	3.7	3.16	117.09
Dovetail mortise-tenon joints	Reinforced	1.76	2.37	74.26	0.63	0.44	143.18
	Unreinforced	3.35	5.36	62.50	3.87	2.66	145.49

Note. Total energy ratio and ultimate load capacity ratio are FEM over experimental.
