Crack distribution statistics of constant moment zone of specimens.

Specimen number	Crack spacing (mm)			lmax/lm	lmax/lmin	Crack height lh (mm)
	lmax	lmin	lm
FDBL	183.6	137.7	168.2	1.09	1.33	260.1
T-1	174.6	95.23	127.0	1.37	1.83	235.2
T-2	141.5	73.2	105.2	1.35	1.93	234.8
T-3	144.8	65.5	115.0	1.26	2.21	245.8

l_max is the maximum of crack spacing, l_min is the minimum value of crack spacing, l_m is the average value of crack spacing, and l_h is the maximum value of crack height.
