Effect of the Nonprestressed/Prestressed BFRP Bar on Flexural Performance of the Bamboo Beam

Table 3

Details of tested reconstituted bamboo beams applied with nonprestressed/prestressed BFRP bar.

Type	Label	b × h × l (mm)	db (mm)	(kN)	as (mm)	ω0 (mm)
Reconstituted bamboo beam	B0	66.6 × 120.7 × 1869	12	0	13	0
	B1	60.8 × 112.5 × 1865	12	18.29	24	3.14
	B2	62.4 × 113.4 × 1870	12	16.73	23	2.87

Note: ω₀ is the calculated initial anti-arch deflection caused by the initial prestressed force based on Eqs. (1) and (2).
