Calculation results of specimens.

Specimens	Pu (kN)	Mu (kN·m)	δmax (mm)	(kN·m)	δ (mm)
B-1	35.0	14.0	35.80	5.68	8.80	0.41
B-2	65.0	26.0	25.47	11.40	8.80	0.44
B-3	60.0	24.0	21.16	10.76	8.80	0.45
B-4	70.0	28.0	31.76	11.72	8.80	0.42
B-5	70.0	28.0	17.10	17.64	8.80	0.63

Note: P_u is the ultimate applied load; M_u is the ultimate flexural bearing capacity; δ_max is the deflection of midspan corresponding to P_u; M_u^′ is the flexural bearing capacity in serviceability limit state; δ is the deflection of midspan in the serviceability limit state.
