Calculate loading Capacity of Triangular Scaffold
A three-dimensional loading system is created by arranging the triangular scaffold elements, which could have triangular or square horizontal cross section. If a scaffold with square or triangle plan in 1.2 meters’ side with one pipe of 50mm diameter in its corner and 2.5mm thickness, as the maximum height of scaffold elements is one meter, the thinness coefficient of vertical member will be:
The virtual pressure stress of such component is 1176 Kg/cm2; therefore, the loading capacity of each scaffold columns include:
Therefore, the load bearing capacity of scaffold with square arrangement is equal to 4 x 4.4 = 17.6 ; and with triangle arrangement is equal to 3 x 4.4 =13.20. This capacity remains valid as long as thinness of one vertical member is more than general thinness of scaffold; however, when the total thinness of the scaffold exceeds the thinness of a vertical member, its value decreases.
For this purpose, we calculate the height of scaffold the thinness of total scaffold as equivalent to thinness of a vertical bar.
