For concrete the parabolic nature of the stress/strain is applied in a section while for steel the linear stress/strain up to its yield value is considered acting on the steel cross section. The prediction of the capacity of a structural section in concrete or steel construction is based on the known stress/strain properties of these materials. This paper will show examples of capacity curves for reinforced concrete and steel sections solved by the analytical method. Some drawbacks of standard software is that it can be inaccessible or expensive.The analytical method precludes the use of the standard flexure and interaction formula in structural analysis and as such is considered as an out of the box method and contrary to the traditional graphical method of solution. This method is hands down the optimal and most common method to evaluate a structure with high precision and low calculation time. Sk圜iv Structural 3D is one such software which allows users to evaluate the effects of point loads, moments and distributed loads on a structure or design ( Sk圜iv S3D Documentation). There are a great number of Structural Analysis Software that can perform the accurate FEA calculations without the difficulty of having to manually set up the complex process. In saying this - FEA is an extremely powerful and accurate method of structural analysis and is the backbone of most Structural Analysis Software. It is common that an FEA model will comprise of matrices thousands of entries - making it pretty much impossible to be evaluated by human calculations.

This can be an extremely difficult and time consuming process to set up and run. FEA requires that the structure is broken up into smaller parts (or elements) which can be evaluated individually for a more accurate estimate of the solution. It is a far more complicated, yet accurate method to run structural analysis compared to hand calculations. Finite Element Analysis (FEA) is a complex numerical method used to solve complicated problems which contain a number of variable inputs such as boundary conditions, applied loads and support types.
