Fixes & Enhancements

The following updates and enhancements have been included in this release:

  • [TSD-6127]1 - The propensity for the deep end of a haunch to become Class 4 has increased with the adoption of EC3 design. To mitigate against this, improvements have been made to the classification of haunched rafters.The Class 4 haunch ‘situation’ has much improved for strength checks, but has not gone away, particularly for member stability checks. For more details, see the following article: Improvements to classification of haunched rafters to EC3
  • [TSD-8907]1 - The facility to carry out a Fire Check to SCI P313 for BS design has been extended to EC3. While there is no guidance in the Eurocodes as these 'Boundary Condition' requirements emanate from the UK Building Regulations, users have indicated that they would find it useful to be able to carry out these checks when the main frame design is to EC3.
