Problem 1 Reinforced Concrete T-Flanged Sections (50 pts.) You are required to analyze and design the propped cantilever t-section from HM 4 but for shear only. Draw shear V and moment M diagrams for uniformly distributed load throughout the 30ft span and equally concentrated loads at 10ft and 30ft. Recall that the connection at the left joint N1 is fixed. The connection at 20ft N3 is a roller. The right end node N2 is a free end. Use a concrete...
