Total load 87 psf = B1W16 x 57 G1W24 x 68 Compute Vmax and Mmax for Beam 1 and Girder 1 in the roof framing plan. 28' H I H- B1 6 @ 6' = 36' B1 B1 B1 B1 | G1 I- I-

1. (a) Calculate the tributary area, AT, for column 2A in the 4th floor (i.e. the column supporting the roof) to be used in calculation of total roof live load on column 1A (note that "roof live load" is different than "floor live load"). (b) Calculate the tributary area, AT, for column 1A in the 2nd floor to be used for calculation of floor live load acting on the column. c) Calculate the tributary area, AT, for column 1B in the 1st floor to be used for calculation of floor live load acting on the column. (d) Calculate the influence area, AI, for column 1B in the 1st floor for floor live load. e) For a specified live load of p. = 40 psf, calculate the design floor live load, pz [psf], for column IB in the Ist floor using floor live load reduction from code (if allowed). () Using your answers from (c) through (e), calculate the axial force, P. [kip], acting at the top of column 1B in the Ist floor due to floor live load. (g) If columns are 16 in. x 16 in. in x-sect, typical floor beams…
