Reinforcement in continuous beams

  1. Nov 30, 2011 #1
    1. The problem statement, all variables and given/known data

    I have been asked to provide a detailed reinforcement plan for a continuous beam.

    This beam has the following dimensions: h=180mm, b=500mm and l=5400mm. The supports are three and located at 200 (roller), 2700 (pinned) and 5200 (roller)mm, creating two equal spans. The loading will occur in the middle of each midspan (1450mm & 3950mm for 0 the beginning of the beams length).

    Concretes maximum gravel size is 16mm.

    2. Relevant equations

    Knowing that the beam will face both tension and compression, reinforcement on the top and the bottom of the beam must be applied.

    My main problems are: 1. what and how many bars should I choose, 2. What concrete cover should I have, 3. what distance between the bars.


    3. The attempt at a solution

    I have been asked to provide several different proposals, either with continuous bars or with bars placed over the middle support and at the bottom of the midspans. I want to have both highly reinforced beams and a lightly reinforced.

    Any ideas?

    Thank you in advance!
