Tank Design And Construction Services
CROM adheres to the highest standards of professional engineering and construction. Tank structures are design and built in compliance with applicable sections of: ACI 372R Guide to Design and Construction of Circular Wire- and Strand-Wrapped Prestressed Concrete Structures, published by American Concrete Institute. ANSI/AWWA D110 Wire- and Strand-Wound, Circular, Prestressed Concrete Water Tanks, published by the American Water Works Association. All design drawings and calculations prepared by CROM are signed and sealed by of one of the company’s full-time registered professional engineers.
CROM specializes in the design of thin-shell concrete structures, a unique subset of structural engineering design. This expertise allows us to maximize the natural physical properties of concrete and steel to design durable, efficient and low-maintenance prestressed concrete tanks. The design of our tanks considers various load conditions such as backfill and seismic design.
- Backfill– Often it is necessary to either partially or fully bury a prestressed concrete tank. Under these conditions, the tank wall and roof are designed to withstand the load from the backfilled soils. The soil load can be uniform or differential, meaning that it can vary in elevation around the tank perimeter.
- Seismic Design – Every prestressed concrete tank is designed to resist seismic-induced forces to ensure a functioning tank under even the most severe conditions.
The complex structural behavior of prestressed concrete tanks regularly demands the use of finite element analyses. Combined with classical structural design analysis, the Finite Element Method (FEM) provides a secondary confirmation of stresses, strains, and deflections of the tank under various load conditions.
When it is necessary to understand the unique flow or mixing characteristics inside a tank due to piping geometry or baffle configurations, CROM can help clients by performing Computational Fluid Dynamics (CFD) analyses. This analysis simulates the fluid flow, heat transfer, and time-dependent flow of the liquid inside tank to assess water circulation patterns and identify the potential for stagnation in the reservoir.
