A two span beam subjected to shear and flexure only is reinforced as follows: Given: Stirrup diameter, ds = 10 mm Concrete f'c = 21 MPa Steel rebar fy = 415 MPa
1. A two span beam subjected to shear and flexure only is reinforced as follows:
Given:
Stirrup diameter, ds = 10 mm
Concrete f'c = 21 MPa
Steel rebar fy = 415 MPa
Stirrup fy = 275 MPa
Beam size b x h = 270 mm x 450 mm
Assume all bars laid out in single layer.
Calculate the following:
a. Tensile steel ratio in positive bending at midspan = _____?______ (in 5 decimal places)
b. Design Moment strength of section at midspan for positive bending = ____?_____ kN·m (nearest whole number)
c. Nominal Moment strength of section at face of support for negative bending = _____?____ kN·m (nearest whole number)
Step by step
Solved in 3 steps with 3 images
Can you give me the final answers. I can't seem to select which one is being solved for a certain question
a. _________ (in 5 decimal places)
b. __________ kN·m (nearest whole number)
c. __________ kN·m (nearest whole number)
Thank you in advance!
