Experimental Study on Influence of Connection Defects on Joint Strength of Half-Grouted Sleeve Splicing of Rebar

Table 1

HRB400 rebar base material testing data.

Number	1	2	3	AVG	Standard
Rebar diameter (mm)	16	16	16	16	—
Yield strength (MPa)	413	413	421	416	≥400
Tensile strength (MPa)	580	584	583	582	≥540

The standard means the demand of rebars according to the specification content of GB50010 [14].
