Pullout Test on Fully Grouted Bolt Sheathed by Different Length of Segmented Steel Tubes

Table 2

Characteristic parameters for tensile test on bolt and pullout test interrupted by bolt-fracture.

Testing measure	Yield load (kN)	Elastic elongation (mm)	Yield lasting (mm)	Peak load (kN)	Displacement versus peak load (mm)	Final displacement (mm)
Tensile test	96	8.5	6.1	145	66.50	107.43
Pullout test	105	7~11	≤4	158	48	55~75
