Structural Strengthening Design and Repair Strategy Associated with Cost Analysis of a Concrete Water Reservoir (5000 m3/ 5ML)
Project Scope
Design of Structural Strengthening to Reinforce a Concrete Water Reservoir in Dubbo.
The geometry of tank was found from the provided limited drawings as:
- Height = 9.98 m ≈10.00 m
- Diameter = 25.15 m
- Wall Thickness = 150 mm
The structural components of tank are presented as follows:
- Reinforced concrete wall thickness: 150 mm
- Ring Steel Reinforcement diameter = 9.5 mm (3/8”)
- Vertical Steel Reinforcement diameter = 12.7 @ 460 mm (Centre)
- Steel Wires around the tank with the density of 34 Wires per foot at the bottom and 6 Wires per foot at the top of the tank
- A 50 mm mortar applied on the wires as a protective layer to prevent the corrosion of steel wires
The following tasks were carried out:
- Modelling and Structural Analysis of the Bridge Utilising SAP 2000 Computer Software in Accordance with AS 3735:2001
- Obtaining the stresses and forces on the deteriorated area
- Structural strengthening design using CFRP Fabrics
- Repair Methodology (Method & Material) and Specification
