Silo and tank construction

In addition to the stress analyses, the global and local stability cases must also be checked. This includes e.g.

Circumferential pressure dents caused by wind load and / or vacuum
Axial pressure buckling as a result of roof and snow loads
Shear buckling due to a torsional moment (eg, agitator)
Local instabilities (eg, ports of consoles, manhole)
Verification of the substructure (e.g. connections, kinks)
Anchoring in foundation (e.g. foot ring stiffener, anchor plate, anchor rods)

The portfolio of containers, silos and tanks includes a wide range of different designs and uses. There are containers with underground installation, substructure or intermediate and standing frame.

Just as different are the performances of the different bottoms from thorispherical, conical, spherical head or flat bottom to the hopper.

Depending on the material or filling, other verifications are used to a greater extent. For example, bulk materials cause additional axial loads during filling or emptying, or earthquakes, which lead to higher loads in the case of axial buckling. In the case of liquids and overpressure, the tensile forces in the shell plate become decisive as a result of the hoop tensile forces. Negative pressure resulting from operation and the effects of wind have an impact on the buckling verifications in the circumferential direction.

Silo and tank construction

SKI Ingenieurges. mbH prepares static and dynamic verifications in the limit state of load-bearing capacity, serviceability, or fatigue for silo and container structures, for both smooth sheet metal and corrugated sheet metal silos. Expert reports can also be prepared in the event of damage.
