Nonlinear Analysis for the Crack Control of SMA Smart Concrete Beam Based on a Bidirectional B-Spline QR Method

Table 2

Designation and parameters of SMA reinforced concrete beams.

Designation	Beam dimension (mm)	Concrete cover (mm)	Reinforcement ratios (%)	Prestrain of SMA wires (%)	Eccentric distances of SMA wires (mm)
B1		25	0.76	6	220
B2		25	0.76	6	220
B3		25	0.76	6	220
B4		45	0.76	6	220
B5		65	0.76	6	220
B6		25	0.46	6	220
B7		25	1.14	6	220
B8		25	0.76	4	220
B9		25	0.76	8	220
B10		25	0.76	6	110
B11		25	0.76	6	160

Note. B1, B2, and B3 are different in depth-span ratios; B2, B4, and B5 are different in concrete cover; B2, B6, and B7 are different in reinforcement ratios; B2, B8, and B9 are different in prestrain of SMA wires; B2, B10, and B11 are different in eccentric distances of SMA wires.
