The self-weight (SW) of the structure is calculated automatically in the analytical model <br />with superimposed dead loads (SDL) added to account for the weight of topping slabs , landscape loads, <br />and other nonstructural components. The seismic mass of the SW and SDL are calculated automatically <br />in the seismic analysis. The live loads (LL) are applied per code requirements. P-Delta effects are <br />automatically calculated. See Section 2 of this report for the gravity loading used at each floor type. <br />The weight of the concrete components is assumed to be 150 pounds per cubic foot (pcf). The cladding <br />load is assumed to be 20 psf (curtain wall, metal panel rainscreen, and fabric screen) and 40 psf <br />(Procelain panelized rain screen, brick/tile finish) for both Residential and Hotel of vertical wall area. <br />The total seismic weight to be considered in the lateral analysis for Residential and Hotel are shown in <br />Section 2 of this report. <br /> <br /> <br />
