Calculate the Load distribution of slabs to beams 3, 4 and C

For each of the building properties listed below, identify which parameter from the base shear equations shall apply. Building occupancy and function Seismic Base Shear In accordance ASCE-7 code, buildings must be designed to withstand lateral forces that are generated during a severe earthquake. The minimum required design force is given in several equations. Design Base Shear, V= C, W Seismic response coefficient, C,, is the smaller value from two equations: In these equations: C₂ = C₂ < Sp! R Spy R Sor & Spare Seismic Acceleration Parameters from USGS maps is Importance Factor Tis Period of Vibration, (depends on building height & must be calculated) Ris Response Modification Factor from ASCE Table Wis the Effective Seismic Weight of the building. SD1 and SDs, seismic acceleration parameters R, response modification factor I, importance factor T, period None of these

Figure 1.2 shows a floor plan consisting of a one-way slab spanning betweenbeams on grid lines A, B, C, and D. The beams are supported on columns at theintersections of numbered and lettered grid lines. Unfactored dead and live loadscarried by the slab are shown. a)Compute the factored dead and live loads based on 1.2D and 1.6 L. b)Determine the tributary width for the beam on Line B and the total factored load (plf) carried by the beam. (Neglect beam weight) c) Determine the tributary area for the column at the intersection of Lines B and 2. Compute the total factored load (lbs) transferred to the column. Assume the column is 12 in. x 12 in. 22-144 200 SHEETS O 3 18' SE Dead: Live: 20' Unfactored Loads W₁ = 100pst W₁ = 70 psf Beam on Line B: Column on Beams Line B/2 Columns One-way slab 4 FLOOR PLAN 20' Trib.width = C 1 Trib. area = - Factored Loads_ 20' Beam Load= Column Load=
