Bolted cylindrical tanks are widely used by manufacturers in various applications. These tanks are typically constructed from carbon steel or stainless steel and assembled in the field using a bolted system. While cylindrical tank structures are generally more earthquake-resistant than prismatic structures, seismic anchoring is crucial, especially in seismic regions, to ensure their stability during earthquakes. Seismic anchor plates play a vital role in helping the tank withstand seismic forces without bending, rotating, tearing, or sustaining damage during an earthquake.
What is a Seismic Anchor Plate?
Seismic anchor plates are steel plates that anchor the tank to the foundation. These plates are placed on top of bolts protruding from the foundation, effectively securing the tank to the base. The design and engineering of these plates are crucial; incorrectly designed or improperly placed anchor plates can cause more harm than good. Since most bolted cylindrical tanks have a water capacity exceeding 100 tons, the overall structural engineering of the tank, including the design of the anchor plate, is of utmost importance. Good engineering and design can be lifesaving in these structures.
Advantages of Seismic Anchor Plates:
- Structural Reinforcement:
- Strengthens the tank structurally against external seismic forces.
- Prevents tank rotation, distortion, bending, and tearing during earthquakes.
- Increased Durability:
- Enhances tank durability, preventing damage during seismic events.
- Emergency Usability:
- Enables the use of critical tanks, such as firewater tanks, even during seismic events.
- Reliability Boost:
- Increases tank reliability, preventing costly damage.
In conclusion, seismic anchor plates are of vital importance in earthquake-prone regions. Just as good engineering is crucial for residential buildings in such areas, it is equally critical for water tanks. The material selection, plate thickness design, and structural calculations of the tank should be well-executed based on the seismic risk level.
