In the joint number: the first number “1” represents steel and “2” represents cast iron, the second number represents the diameter of the steel, the third number represents the anchorage length, and the last number “1∼3” represents the three repetitive specimens; if there is an “s” before the last number, it represents the steel is placed eccentrically in the sleeve. For example, “1-16-100-1” represents the first steel sleeve specimen with a diameter of 16 mm and an anchorage length of 100 mm.
