Note. The height of profiled steel sheet is 75 mm. is the thickness of bamboo plywood; is the thickness of profiled steel sheet; is the height of composite slab; selftapping screws spacing, A, B, and C: A is the uniform spacing on top bamboo plywood, B is the close-set spacing on top bamboo plywood in dense zone, and C is the uniform spacing on bottom bamboo plywood. The screw spacing of a lateral plate is the same as the bamboo plywood.
