English Abstract
Voided cylindrical shell is a sustainable reinforced concrete roof system.
Two directions of the voids system with two types of the voids shape in each direction had been used in this experimental work.
Circular and squared void shapes used as continuous voids in the uniaxial direction while spherical and cubic void shapes used as separate voids in the biaxial direction.
The diameter of the circular or spherical void is (70mm) and an equivalent side length of about (62.5mm) was used for the squared or cubic voids.
The experimental variables were included the type of the shell, direction of the voids, shape of the voids and a number of the steel reinforcing layers (bottom or top and bottom) .
The cylindrical shells tested as simply supported under one-point load at the crown of the shell.
By (37%) maximum reduction in the concrete volume, the ultimate load capacity decreased by (35%).
As well as, use of the voids in the biaxial direction improved the structural behavior in comparison with the use of voids in the uniaxial direction as a hollow core section.
The use of square section or cubic void shape gave a better structural performance than the use of circular section or spherical void shape in both directions.
