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 […]
