Asce 7 22 Portable File

However, beware: If your portable unit is stacked (two-story portable office), the 7-22 code prohibits the free-rocking exception. Stacked portables must be treated as fixed-base structures with explicit seismic connections. Inside a portable building, everything moves: server racks, lockers, medical equipment, and furniture. ASCE 7-22 Section 13.2.1 now requires that portable structures with casters or wheels have all internal components independently braced for ( F_p = 0.6 S_DS W_p ) (up from 0.4 in 7-16). This is a 50% increase in internal bracing loads.

ASCE 7-22 introduces based on updated maps (incorporating the 2018 NSHMP model). For portable structures: 4.1 The "Free Rocking" Exception Portable structures mounted on elastomeric pads or wheels are considered "self-centering" if their height-to-width ratio is < 0.5. For these units, ASCE 7-22 allows a reduced seismic response coefficient (R = 4) instead of the standard R = 1.5 for non-ductile portable buildings. ASCE 7-22 Section 13
