3 <br /> Project:514 Waverly Ave, Everett, WA 98201 <br /> 1.1 Seismic Design <br /> Criteria Basic Seismic-Force-Resisting System Diaphragms/Shear Walls <br /> Medium Building Height H = 15 ft <br /> Seimic Use Group II <br /> Importance Factor le = 1.0 <br /> Site Class D <br /> Seismic Design Category D <br /> Response Factor R = 6.5(light frame wood building) <br /> Mapped Acceleration Ss = 1.35 <br /> Si = 0.46 <br /> Design Acceleration SDs = 1.01 <br /> SDi = NA <br /> Seismic Response Coefficient Cs = SDs/(WI) <br /> 1.01 /(6.5/1.0) = 0.16 <br /> Building Weight(Addition only) <br /> The weight of the walls is applied by adding 5 psf to the roof DL(upper half of walls)and 10 psf to the floor DL <br /> (full story height) <br /> W = (15+5)x 550 sgft = 11,000 lbs <br /> Base Shear VBase = Cs x W =0.16 x 11,000 1,760 lbs <br /> Design Shear: To convert from strength level to ASD, Base Shear is multiplied by 0.7 <br /> VDesign = 0.7 x 1,760 = 1,230 lbs <br /> Per Grid: 0.5 x 1,230 = 615 lbs <br /> tecinstruct LLC <br />
