Concrete design to EN [L H Martin; J A Purkiss] -- Comprehensive text for teaching the concrete structural Eurocode. ENV results from a programme of work sponsored by the used in conjunction with this NAD, for the design of concrete.

The formulations proposed by both the codes are very similar but the Eurocode adopts a more refined approach to account for viscous effects by considering the influence of environmental conditions, notional size of the elements, strength class of the concrete and age of the concrete at the time of loading; whereas the American code uses a simplified approach based on the ratio between the sustained load and the total load.

The main problem with the curvature approach is that it assumes that configuration of the column at collapse is always stable whereas, if the axial force exceeds the critical value, this is not true and the equilibrium could not be enforced. Figure 8: second order moment in the model column.

Such analysis must explicitly model material nonlinearity and account for creep and imperfections and thus requires a high computational effort. For this reason its application to the analysis of entire buildings is fairly limited but, on the contrary, this method represents a very powerful tool for the evaluation of local effects in isolated members, whose internal forces have been calculated by an elastic second order analysis of the entire structure.

In this way it is possible to obtain very accurate results by considering the effective distribution of moments along the element. Figure nonlinear stress-strain diagram for concrete.

Figure elastic-perfectly plastic stress-strain distribution for steel Comparison of the analysis methods for the evaluation of local second order effects In order to determine the accuracy of the available methods for the evaluation of local second order effects in concrete members, the results in term of maximum axial capacity obtained for the same model column have been compared. The approaches that have been taken into consideration are: 1.

The case study was represented by an isolated column with a section of 30 by 30 cm and an effective length of 5 m subjected to an eccentric axial load. The capacity corresponding to the nonlinear analysis has instead been estimated based on the curves obtained from a displacement control analysis at fixed eccentricity see Figure Figure maximum axial capacity of the column calculated through the simplified methods.

All the tested configurations are reported in the following table. In order to evaluate the accuracy of the simplified methods, the results corresponding to the nonlinear analysis have been assumed as reference values.

The same comparison has been repeated for another model column with the same properties but a lower effective length, reduced to 3 m. By looking at the detailed graphical results reported in the figures below the nominal stiffness method appears to be more accurate in predicting the behavior of each configuration of both the long and the short column and produced conservative results for almost any range of admissible axial forces.

The nominal curvature approach on the contrary, resulted over-conservative for low values of axial force while it became unconservative for increasing value of N. Both the simplified methods slightly underestimated the response of the short column for high values of axial force. A correct design approach must take into consideration all these aspects in order to prevent possible local failures of slender members.
