Installing earthquake bracing
Next, each column must also be secured to the floor. This is accomplished by
installing one of two available anchor kits. Select the anchor kit by comparing
the site requirements to Table 60 on
anchor kit can be used to meet the CALIFORNIA OSHPD specification, but
only Kit B meets the BELLCORE specification. For those installations where
neither specification is required, Kit A is recommended due to its shallower
concrete requirement.
Both anchor kits can be used in hardrock concrete as long as the compressive
strength exceeds 20.7 MPa (3000 psi). Only Kit A can be used in lightweight
aggregate concrete with a compressive strength greater than 27.6 MPa
(4000 psi). The floor parameters for your installation can usually be found in
the engineering building drawings.
