| The RAPT
analysis and design package for reinforced and post-tensioned concrete structural systems has been written and developed by practising structural
engineers as an everyday design tool. It is comprehensive in its treatment
of the analysis and design of structural concrete.
* RAPT allows optimization of a prestressed concrete
solution with the ability to investigate a number of possible
configurations to a high degree of accuracy very
rapidly. |

Official realease of RAPT version 7.1.3.0 available for download from downloads page. See Upgrade Notes for details. Including
- A complete rewrite of the method for calculation of deflections from section curvatures to remove the inconsistencies in the older versions. This should remove previous inconsistencies in results which showed as discontinuities or kinks in the deflected shape near support locations. This has also fixed the previous inconsistency with deflections for cases with significant support settlement. The new method is described in the Theory section of the Help, T 7.7.1.
- Addition of a Linear Shrinkage profile in Design Data - Deflections for the calculation of deflections for members where the concrete shrinkage is different at the top and bottom surfaces, eg with Metal Decking.
- In previous versions, in the long-term section analysis of sections, creep was modelled in the section analysis but the shrinkage effect was added as an extra curvature. To allow for the variable shrinkage in the Linear Shrinkage model mentioned above, the effects of both creep and shrinkage are now modelled in the section analysis to determine the long-term curvature of the section under permanent loads.
