Abstract

It is well known that facilities like storage reservoirs and tanks have a great priority as it serves mainly
for portable drinking water for a huge population. In general, water tanks are designed based on their
shapes and ground positions. In this comparative study an attempt is made to consider a rectangular
reinforced concrete (RC) ground water tank of a real full scale as a case study in Duhok city. Two identical
surface water tanks of a 9000 cubic meter capacity and having 50 mm joint in between have been
undertaken in this study. The tank were analyzed and design manually based on working stress method to
ensure that it is crack-free to avoid any leakage. The outcomes were then evaluated using ETABS,
SAP2000 and SAFE software by performing three dimensional (3D) analyses. The mat foundation and top
slab of the tank were analyzed using SAFE software. The study involves calculations of bending moments,
shear forces, and reinforcement. The tank walls are subjected to dead load and hydrostatic load due to
water. A parametric study has been undertaken also by considering water level and soil bearing capacity
as variables in this investigation. A good agreement has been obtained in this comparison. It may be
deduced that a design software can be used accordingly with a reasonable degree of accuracy than manual
calculations. This can maintain a reasonable cost and avoid human errors in any structure which is a
critical local and global issue nowadays.
