ACI -350-3-06 for seismic design of soil pressure with concrete structure . UBC -97 for earthquake load combinations. ASCE for load combinations. Compressive strength of Concrete “f′c”. For columns and footing f′c = 28 Mpa For slabs and beams f′c =24Mpa For all other elements in structure such as blinding and bracing f′c = 12 MPa Yielding strength of steel fy = 420 MPa. Material Property Soil Property Soil bearing capacity = 124 KN/m2 Soil profile = SE Dead loads (D.L): 5 .05KN/m2 Super Imposed dead load (SI):6.1 KN/m2 Live Load (L.L): 5 KN/m2 (for all floor except stair roof) 10KN/m2 ( for stair roof) Lateral loads consider earthquake load.
