Seismic Specification in Steel Silo Design

Silo Types

Silo System

Seismic fortification intensity of 6 degrees corresponding to the design basic seismic acceleration value is 0.05g;

Seismic fortification intensity of 7 degrees corresponds to the design of the basic seismic acceleration value is 0.1g;

Seismic fortification intensity of 7.5 degrees corresponding to the design basic seismic acceleration value is 0.15g;

Seismic fortification intensity of 8 degrees corresponding to the design of basic seismic acceleration value is 0.2g;

The seismic intensity of 8.5 degrees corresponding to the design of the basic seismic acceleration value is 0.3g;

Seismic fortification intensity of 9 degrees corresponding to the design basic seismic acceleration value is 0.4g.

In 2008, the epicentral intensity of the Wenchuan earthquake in Sichuan Province, China reached X, which was the same as the epicenter intensity of the Tangshan earthquake. The distance from the epicenter about 80km has been greatly reduced. Where the area exceeds 100 km, the intensity is substantially V.
