Name: _SOLUTION_ _ _ _ _ _ _ CE 441 Reinforced Concrete Design – Workshop 4: Design of Shear Reinforcement Thursday Oct. 15, 2009 Due at the end of class 1. Design the necessary shear reinforcement using double leg stirrups for a rectangular section as follows: f c ’=3 ksi, f y =f yt =60 ksi, V u =100 k at the critical section to be designed for shear. The cross-section has the following dimensions: width b = 18 in., effective depth d =25 in., total depth h =28 in., A s =4 in 2 . Determine the maximum spacing of #4 double leg stirrups at the critical section. 2. For the beam shown draw the shear envelope due to factored loads, compute the design shear V

Unformatted text preview: u at the critical section under factored loads and determine the maximum spacing of #4 double leg stirrups that are needed for the critical section in shear. Section geometry is defined as b =18, d =20.5 in. d=2.5 in., h =24 in., A s =6#10, A s =2#9, the uniformly distributed dead load, including the self-weight of the beam is w DL =6 k/ft, and the uniformly distributed live load is w LL = 2 k/ft as shown. The yield strength of the shear reinforcement is f yt =60,000 psi. The yield strength of longitudinal reinforcements A s and A s ' is also 60,000 psi. 2)...
