NONLINEAR STRESS ANALYSIS OF REINFORCED CONCRETE STRUCTURES BY ELEMENT METHOD

A nonlinear stress analysis, including the elasto-plastic behavior of concrete and steel in addition to the limiting tension of concrete, is presented. The results of the numerical examples indicate that this type of analysis offers a complete picture of this stress distribution both in concrete and in steel. The effect of bond between steel and concrete and the influence of creep and shrinkage of concrete are not considered but could be incorporated in the analysis when more reliable information is available on the effect of the bond. It is pointed out that the accuracy of the analysis as with all finite element analysis depends on the fineness of mesh size which is particularly critical in this analysis since a whole element is considered to be cracked in the direction normal to the one in which the tensile principal stress exceeds the prescribed limiting tension. If a finer mesh were used, a more realistic crack pattern could be obtained at the expense of more computer time. /TRRL/
