Bending Performance of Precast Lightweight Aggregate Concrete Exterior Wallboard with a Concealed Rib Sandwich Structure

Table 4

Eigenvalue of deflection of the specimen.

Number	Δcr (mm)	Δy (mm)	Δu (mm)
Slab 1	0.84	3.54	13.43
Slab 2	0.89	3.56	13.45
Slab 3	0.60	2.57	10.96
Slab 4	0.49	2.53	10.75

Note. Δcr is the cracking deflection, mm; Δy is the yield deflection, mm; Δu is the ultimate deflection, mm.
