How much do you know about seismic supports?

Why can seismic supports resist earthquake forces?

An earthquake is a vibration caused by the release of energy from the earth's crust, which affects or even destroys human life through seismic waves.

Seismic waves can be divided into three forms: longitudinal wave (P wave), transverse wave (S wave), and surface wave (L wave):

Longitudinal waves are propulsion waves, which make the ground vibrate up and down, and are relatively weak in destructiveness;

S-wave, or s-wave, belongs to shear wave, which makes the ground vibrate back and forth, and has strong destructive power; surface wave is a mixed wave excited when P wave and S wave meet on the surface, which is very destructive.

Although gravity supports and hangers can resist and reduce vertical seismic forces (ie longitudinal waves), seismic supports and hangers can resist and reduce horizontal seismic forces (ie transverse waves) through their special diagonal support structure.

But one thing to note is that the function of seismic supports and hangers is mainly "seismic resistance" rather than "load bearing". The prerequisite for the installation of the seismic support and hanger is that the gravity support and hanger should meet the conditions and can meet the gravity action of all vertical pipelines and media, that is, the function of the gravity anti-seismic support and hanger is not considered and can meet the functional requirements. Generally speaking, it can be summarized as: there is gravity on the seismic support, but we did not consider the gravity effect of the seismic support and hanger in the design calculation, that is, did not consider the gravity co-support. (Except for special circumstances, there may be gravitational co-support in some small spaces.)

How to distinguish seismic supports?

Earthquake-resistant brackets, pipe gallery brackets, photovoltaic brackets, integrated brackets...the variety of support types is dazzling. The name of the bracket is usually named after its function and application scenario. The brackets can also be divided into finished brackets and non-finished brackets according to their installation methods.
