HOW TO READ THE TABLE

The table refers to bulged staves, bulged staves for external use and smooth staves. For the holed staves, the loading capacity is 15% less. The datas have been obtained operating on staves rested on the two extreme sides and joined together by means of a screw M8 positioned on the middle of the span. The weight on them was uniformly distributed.
For each distance between two subsequent supports, we give different value of loading capacity: the first line correspond to the maximun loading capacity, the subsequent lines show the loading capacity relating to the most used rises.
In all the tests we always reached the collapse point of the staves: this happen when the test load is three times more than the maximum allowed one.

HOW TO USE THE TABLE: we want a walking surface capable to support a weight of 550 kg/m² with a distance between two subsequent supports of mm 1.500: looking at the table, with such distance , we find that we can use staves 12/10 with a rise 1/300 and a loading capacity 585 kg/m² or staves with thickness 15/10, rise 1/400 and loading capacity 558 kg/m².

When the rises requested are different from those indicated in the table, modify proportionally the load.
EX.: with bulged staves 15/10 on a distance of mm 1.500, the maximum loading capacity is 1.043 kg. with rise of mm 7 equal to a ratio rise/distance of 1/214 as indicated in the table.
If we want to modify the ratio rise/distance from 1/214 to 1/350 we will obtain a loading capacity: (1.043 x 214) : 350 = 638 Kg/m²
