What is the rib height of steel deck

What is the rib height of a steel deck? We understand the rib height of the steel deck from the expression and graphics of the steel deck model.

Taking SD51-305-915 steel deck as an example, its basic parameters are:

      Rib Height: 51 Rib Spacing: 305 Effective Width: 915

Through the above example, I think I should have a very clear understanding of the meaning of the steel deck rib height.

In addition, the main indicators for a plate type to determine its own moment of inertia and support span are the rib height and rib distance.

But the rib height is neither the lower the better, nor the higher the better.

If the rib is too low to withstand the load-bending moment effect from the weight of the freshly poured concrete mixture on top of it, there will be too much deflection and the slab will not function properly. If the rib is too high, the thickness of the floor slab will increase and affect the usable space, which is especially obvious when making partitions.
