h S <br /> W1'07066787 — Bldg.40-31.1 slazak Install —Foundation Calculations <br /> Project Description: <br /> The calculations hereon are for a new foundation to support a Mazak 5-Axis Router <br /> equipment in the first floor of Boeing Bldg. 40-31. Construction of the new footing <br /> requires removal of an existing footing for a different piece of equipment that encroaches <br /> partially on the area required for this new footing. <br /> For lateral loads, the Mazak equipment was considered as a Rigid Nonbuilding Structure <br /> per ASCE 7-10 Section 15.4.2, and the lateral load was computed per formula 15.4-5. <br /> STRUCTURAL NOTES: <br /> I. SEISMIC IMPORTANCE FACTOR le= 1.0 <br /> 2. MAPPED SPECTRAL RESPONSE ACCELERATION PARAMETERS: <br /> Ss =1.446, S 1 =0.558. <br /> 3. DESIGN SPECTRAL RESPONSE ACCELERATION PARAMETERS: <br /> SDs=0.964,SDI =0.558. <br /> 4. SEISMIC DESIGN CATEGORY: D <br /> 5. ANALYSIS PROCEDURE: RIGID NONBUILDING STRUCTURES PER <br /> ASCE7-10 SEC. 15.4.2. <br /> 6. FOUNDATION: ALLOWABLE SOIL BEARING PRESSURE ASSUMED <br /> Fb= 1,500 PSI <br /> • <br />
