The Modular Mold Resistant Difference

In order to investigate the strength differences of modular panels with 5×50 straps and 6×50 straps, a 100×50 modular panel with 5cm and 6cm straps, 5 mm in thickness, were evaluated by taking advantage of SPA and Shell Element software. In this study, the concrete pressure is computed from the relation mentioned in ACI guidelines which takes the following form: ‭- Each panel has been studied in two situations:‬ A) Panel relying on only three pins and wedges in all the length...

Prop calculation

Ceiling jacks are the most suitable and economical means for the implementation of concrete slabs and joist blocks, which are produced at heights of 3 to 4.5 meters and are made of first-class pipes of 5 and 6 centimeters in diameter, which also have holes for height adjustment. Prop made from two part that adjustable in length, up and down parts. The lower part is made of tube with a diameter of 60 mm and thickness is 2.5 mm. the upper...

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...
