Numerical Analysis on the Bending Capacity of the Concrete-Filled Micro-Steel-Tube Piles

Table 1

Dimension of CFMST piles.

No.	L (m)	Concrete strength grade	D (mm)	t (mm)	f y (MPa)
CFMST pile 1	1.5	C30	140	4	235
CFMST pile 2	1.5	C30	168	5	235

Note. L and D denote the length and diameter of the CFMST pile, respectively; t and f_y are the thickness and yield strength of steel tube, respectively.
