Compare these moments to those of part (a). c) Design a rectangular section for the entire beam using the moments from part (b). d) Draw influence lines for shear at critical sections and determine the maximum shear at each section using only full-span loading.
Design a rectangular beam continuous over three spans as shown in the accompanying figure. The live load is 2.4 kips/ft, and the superimposed dead load is 1.6 kips/ft in addition to the beam weight. Supports are 16″ wide. Assume fic = 4,000 psi, and f1= 60,000 psi. a) Is ACI simplified method of analysis for […]
