Add features in GSA allowing for analysis and design of prestress concrete (pre-tensioned and post-tensioned); tendons , losses calculation, ULS and SLS checks for prestress concrete members (flexure, shear, torsion), export analysis data into the drawings format etc.

- analyse sections within GSA with forces of a specific load case or combinations
- plot utilisation factor diagrams or similar on GSA model.

Depends on the completion of 'Generalise Section Objects'

#section #design #system

GSA graphics interface upgrade
1) Improve drawing in 3D
2) improve sculpt capability:
- snapping, trim/extend features
- AutoCAD style drawing ability
- move elements from node to node by picking these
3) overcome mismatch of node display and node hot-spot
4) improve visibility of annotation (e.g. draw in front of lines and fill)

#graphics

1) Overhaul GSA results management so as to
- speed up the opening of large models
- speed up the saving of large models, including the saving of backups
- speed up results access
- store post-processed results
2) Provide results management console, for user control.
3) offer batch calc of post-processed results

#system

Improve the analysis stages so that the software can:
- Lock in stresses and carry these forward to stages (similar to Midas)
- Allow loads to be applied at a construction stage that do not then lock in / affect the time dependent effects (eg wind on a construction stage)
- Allow simple plotting / output of results at each stage
- Take account of time dependent effects in staging (creep, shrinkage, etc)

Calculate RC slab deflection based on stiffness of cracked section.

Depends on 'Generalise section object'.

#rcslab #analysis

* Rationalise Grid Planes, to disassociate span directions
* Introduce grid loading on 2D elements
* Introduce Area loading
* Allow loads to be applied in cylindrical axis directions

#object #tool

1) Design rationalisation:
* Introduce reinforcement strips.
* Provide convenient way of specifying reinforcement directions in a strip.
* Offer strip templates.
* Offer option to automatically rationalise reinforcement within strips.
2) Offer code based deflection checks.
3) Offer punching shear checks.
4) Allow reinforcement direction to be wrt user axis
5) Move to Design Layer
6) Option to average reinforcement across defined width

#rcslab #design

easier building output into report - compiling text and graphical views, page numbers

#report

* Currently too brief
* Add more graphical explanation
* Arrange such that help can be displayed alongside GSA window instead of always on top
* More tutorials

#manual

* Specify by second property per element/member
* Only permit tapering between sections of same shape

Depends on 'Generalise section object'

#object

Calculate RC beam deflection based on stiffness of cracked section.

Depends on 'Generalise section object'.

#rcbeam #analysis

Implement layer in GSA for definition of composite floor offering automatic and manual beam width definition.
Design carried out by API link with Compos.

Depends on 'Generalise section object'.

#compos #design

Implement option to apply releases by stage to allow:
After implementing the Compos engine into GSA for design purposes, allow the user to toggle between using the same model for footfall vibration analysis and for static checks. This would for example allow the beam ends to be fixed for the footfall vibration (though with user-overides) but maintain them as simply-supported for a static composite beam check)

#object #analysis

i.e. checks for global buckling
- Implement… if possible?

#tool

Ability to easily generate 3D pdf of the model geometry / contour plot results directly from GSA

#interop

Allow incremental push-over load with constant other loads.
