Need references about RC column design

Need references about RC column design

(OP)
Could you please suggest me references (books, papers, web links etc.) dealing with design and analysis of slender RC column design under bi-axial bending.

thanks

RE: Need references about RC column design

For ordinary slendernesses (typically at much to h/t=30) one may find guide in the codes, say ACI 318 or EHE. The procedures used in the codes should likely be valid beyond that, the codes sometimes quoting that the limit is set mainly on that the tests have been performed typically just for member of such maximum slenderness.

The procedures in the articles of EHE (not very advanced) you may find in worksheets freely downloadable from the Mathsoft's Mathcad Collaboratory site.

Really one may devise in comonality with steel a general procedure in which material and geometrical nonlinearity is introduced. The only thing is that the codes are conservative in not promoting slendernesses beyond what those tested. Particularly, the set of construction procedures and design checks established in the codes are incardinated. Following these and within the realm of more or less ordinary structures, rheological effects like creep or shrinkage, or the even more scarcely remembered lesser strength of concrete under sustained loads can be quite readily forfeited if not forgotten. But if you go very slender and thin, these effects will take its toll (have done, really, in some shell structures failed under buckling happened after creep deflection) as what is relevant is the true nature of the material and structural tipology we use. So if you venture beyond slenderness 30 (better even within typical PC parts, I would think) one should ensure that enough of the time dependent and other rheological effects have been contemplated to forfeit any bad structural behaviour.
