Seismic Engineering in California
Seismic engineering for pallet rack ensures your storage system can survive an earthquake without collapsing. In seismic zones (California, Oregon, Washington, Alaska, Utah, Nevada, and parts of other states), this isn't optional — it's code-required. The calculations determine base plate sizing, anchor bolt specifications, frame bracing, and overall system configuration to resist lateral seismic forces. California is the largest warehouse market in the US by a wide margin. The Inland Empire (Riverside and San Bernardino counties) alone has more than 1.5 billion square feet of warehouse space. The ports of Los Angeles and Long Beach handle roughly 40% of all US container imports, feeding a massive network of distribution centers stretching east through the IE.
