Seismic devices for floor-mounted seismic isolation in specially rated buildings must perform above the design seismic force

Change a static facility without vibration isolation from a normal anchor to a seismic anchor

Earthquakes occur in all seasons, and seismic design for functional purposes should not be installed selectively based on economic considerations, but should be responded to reliably and conservatively to overcome construction errors. This article introduces the method and application of seismic protection for mechanical equipment installed on the floor based on domestic seismic design standards developed on the basis of American and European standards in earthquake-prone areas. /Editor's note

◇ The seismic performance goal for non-structural elements of special class buildings is 'functional performance'.

The non-structural elements of a typical building include both architectural non-structural elements and mechanical and electrical non-structural elements, and the classification of targets according to the performance targets of special class buildings can be easily understood by looking at Table 1.

Structural review is performed by a structural engineer, and the field application review of non-structural elements of buildings has a relatively large number of cases and application theories.

However, mechanical and electrical non-structural elements need to solve interference factors in a limited space, and due to the different fixing methods for each system, the provided specification information is not disclosed until the material is approved, making it difficult to apply easily, and many difficulties arise, such as changing the capacity of the equipment according to the change of use. In order to prevent the displacement of mechanical facilities and achieve the goal of seismic design for functional performance, we will first introduce the seismic voids method by equipment installation location.

Hereafter.
