Earthquake resistant connection

OCM, Inc., introduced Basepack to the U.S. market as a way to strengthen column-foundation joints to resist earthquakes. Basepack affixes to the steel frame on the foundation using proprietary nuts, washers, and grout. The system is available in two sizes: Type A is for small- to medium-size houses and office buildings; Type B is for large-scale buildings and warehouses. According to the company, Basepack is more than 1.2 to 1.3 times as strong as the column it supports.
