Mr. Steve Miller <br />May 20, 1993 <br />Page 2 <br />3. UBC Section 2304(d) - Partition Loads <br />• Office floors and retail - 20 psi <br />4. UBC Section 1712(b) - Vehicle Barriers <br />• 6,000 lb. horizontal load at 18" above the parking surface <br />5. Underground Perimeter Wall Loading <br />• Wall loadings shall be in accordance with the soils report. <br />6. Wind Loading: UBC Section 2316 <br />• P=CeC q I <br />• Ce = per bBb Table 23-G, Exposure C <br />• Cq = per UBC Table 23-H <br />• qs = 16.4 psi (based upon 80 mph basic wind speed) <br />• Importance Factor I = 1.00 <br />7. Seismic Loading: UBC Section 2333 and 2334 <br />• V = (ZIC/Rw)W <br />• 2.b - Seismic Zone 3: Z = 0.30 <br />• 2.c - Site Geology: site type = S , site factor (S) = 1.2 <br />• 2.d - Occupancy Category: IV. S2tandard Occupancy <br />Importance Factor I - 1.00 <br />• 2.e - Configuration requirements: "Regular" structure <br />• 2.f - Structural System: Rw=8 <br />The structure is a building frame system with concrete beams, slabs, and columns carrying the <br />gravity loads. Resistance to lateral load is provided by concrete shear walls with columns acting <br />as boundary elements of the shear walls. Therefore Rw = 8. <br />Sincerely, <br />SI, LINGZD MAGNUSSON BARKSHIRE INC. <br />�1��'\�j a-72af�,.Q� <br />Don Davies <br />DWD/gpo <br />The above loadings and lateral design equations are consistent with the City of Everett <br />structural design code requirements, and are approved for use on the Colby Square project. <br />APPROVED BY: <br />CITY OF EVERETT <br />DEPARTMENT OF PUBLIC WORKS/ <br />BUILDING DEPARTMENT <br />02 <br />Date: <br />SWUN(AhRI)1L%cm\s'os R%ResmR€ Ixc <br />Consulting shudulaland Civil Enginceis <br />
