- For the conditions shown in Figure , use LRFD and a. select a W16 of A992 steel. b. select a steel pipe. c. select a square HSS. d. select a rectangular HSSA W10x30, 3.1 m long, A36 steel is used as a column with fixed ends to support a service dead load of 274 kN. Calculate the maximum service live load the column can sustain using LRFD. Use theoretical value of k. Write your answer rounded to the nearest whole number in kN. A = 5,703 mm2 rx = 111.25 mm ry = 34.80 mmDesign the beam to carry the load as shown in Figure. Use rho max with a strain in the tension bars equal to 0.004 and in the design process use 60% of this rho max. f’c= 21MPa and fy=276MPa What is the Mu max that is to be used in the design? Determine the required base and effective depth of the beam. Round up your answers to the nearest 10mm and use 2b=d Determine the most economical number of 20mm diameter bars required. Using the b and d from letter (b) determine the balanced As for the beam.
