Is anyone aware of a requirement to control crack width in a reinforced concrete corbel to eurocode 2? Could I just take the area of the tension strut and check the minimum rebar controls cracking?
Thanks for your thoughts!
What I'm trying to do (for completeness in my software) is to provide an analysis of a simply supported RC beam at intervals of span/20 - BM, SF, depth of concrete compression zone, lever arm and force in tension steel. For a singly reinforced beam it's a trivial exercise since there can be only one solution at any point.
What I can't seem to see, despite consulting several books, is the assumed distribution of forces in a doubly reinforced beam: obviously some of the moment is carried by opposing compressive and tension bars with the rest being taken by the compression zone concrete and tension steel. At a point where (say) the applied moment is one third of the maximum design moment it's probably the case that it could be resisted by the reinforcement only or by the section without the compression reinforcement, but presumably the correct answer is some of each. Help appreciated.
I have been trying to find solutions to composite column design, that is for example a circular column filled with concrete.
Is there any quick approx. (rule of thumbs) solution like design tolerance of the steel column multiplied by any X number that gives a result within 10% of correct solution.
I know there are two wayÂ´s to calculate this type of columns to EC, that is the official solution and the simplified solution. What i am looking for is an even more simplified solution
If any one could help me with this or give me a hint on where I can find a spreadsheet or some freeware where I can design this type of problem that would be much appreciated !
(My English is probably not 100% sorry for that)
