What are the seismic anchoring requirements for granite outdoor trash cans?

Granite outdoor trash cans are heavy and durable, but in seismic zones, they must be properly anchored to prevent tipping, sliding, or becoming hazardous projectiles during an earthquake. Seismic anchoring requirements are typically dictated by local building codes, which reference standards like the International Building Code (IBC). The primary goal is to secure the trash can to a concrete foundation or slab. This is usually achieved by embedding anchor bolts into the concrete during its pour or using post-installed epoxy or mechanical anchors. The base of the granite trash can often has pre-drilled holes or a steel anchor plate for this purpose. The specific design load—the lateral force the anchors must resist—is calculated based on the weight of the bin and the seismic acceleration forces for the specific geographic location. It is crucial to consult a structural engineer to determine the exact size, type, and number of anchors needed, ensuring the installation can withstand seismic forces and protect public safety.
